Murphy’s Law: “Anything that can go wrong, will go wrong.”


When trying to enjoy our favorite pastime, Murphy’s Law comes into play …and there are many problems that can rear their ugly head, and none are more unwelcome than the dreaded flat tire. Not only can tire problems end your day of riding quickly, but changing tires and tubes is among the most frustrating (and time-consuming) tasks we can think of.


In the ISDE racing, riders must observe strict rules and time allowances for changing tires and do them with no outside assistance. Watching the ISDE racers change tires proves that practice makes perfect and there’s both a correct and efficient way to do it.


In this article, we’ll look at ways to avoid flat tires via good preparation and a few products that you can use to save your day when the dreaded flat tire demon strikes.




One of the biggest causes of flat tires is under and over-inflation. When tires are under-inflated, the tire, rim and especially the tube become much more vulnerable and the resulting tube movement can cause valve stem damage, causing a flat.


Over-inflated tires can lead to an increased load on sidewalls, more exposed surface area as well as contributing to shorter tire and tube life in general. Neither situation is optimal and not only lead to flat tires, but also unsafe handling characteristics.


Checking tire pressures should be performed prior to every ride without fail...this is easy to forget but important. Always use a low pressure gauge as outlined later in this article. Tires that show problems in your garage certainly aren’t going to get any better after you load them in the truck.


What tire pressures should you run? No single answer to this question, but you can find tons of discussion this HERE.

Many times when the dreaded flat demon strikes when you are within distance of your truck or trailer, the opportunity to fix it presents itself.


Relax…Breathe. I’ve seen many riders and racers rush through the tire changing procedure only to find out they’ve punctured the tube during the process and ruin the only spare they’ve brought.


A few tips: make sure the surfaces are clean and free of dirt, inflate the tube slightly before insertion, check for debris around valve stem, make sure surfaces have baby powder applied, be extra careful around the rim lock/stem and most of all, take your time. We’ve also found that the factory supplied rim strap is fairly ineffective so we also use a thin strip of duct tape on the rim surface cut precisely to fit in the rim groove against the spokes.


The most important thing is to treat the tube with care and be patient when installing it, because once you’re even slightly nicked the tube, you’ll have to start all over again.



Treat these with care!




Rim locks and bead locks are strange little items that only off-road motorcyclists know about…because street bikes and scooters don’t have them. Even though they’re a pain in the butt, rim locks serve a very important purpose…to keep the tire from spinning on the rim under acceleration and preventing the tire from coming off if the tube is flat.


When rim locks fail to stay in place, they allow both the tire and tube to spin. This places the valve stem in great jeopardy and a few inches of movement will actually shear the valve stem right off the tube, resulting in a catastrophic failure and a non-repairable tube.


There are better alternatives to the cheap factory supplied rim lock setup such as the LiteLock from Motion Pro - a lightweight plastic rim lock that features a one piece molded design made from special high-strength nylon composite and a beveled washer that are 10 to 20 percent stronger than cast aluminum rim locks and only half the weight.





Motion Pro LiteLoc Rim Locks




As our sport isn’t cheap, sometimes a bit of penny pinching can occur in the wrong place…like buying tubes.


If you walk into your local motorcycle dealer and ask for a common 110/90x19 tube, you may have a myriad of products presented…everything from the standard $18.99 BikeMaster unit to the $44 ultra heavy duty MSR alternative. We’ve used both types and found the MSR heavy duty tubes to be very resistant to punctures and are worth every penny.


Standard tubes are also made with street bikes and overall cost in mind and are very thin, while most of the heavy duty options such as MSR, Bridgestone, Dunlop, etc. are usually 2.5mm or thicker so look for this measurement as your benchmark when buying heavy duty tubes. Look for a box marked similar to this one:



Look for the words "Heavy Duty" and "Puncture Resistant" on the box.




Changing off-road tires is difficult and you can use all the help I can get. There are many products that address this problem and can make this job a lot easier. Here are some of my favorites:


Motorsport Products Tire Changer with Bead Breaker: Forget the old 5 gallon bucket…this portable tire changing stand provides a compact answer to both holding the tire and has an integral bead breaker to help with the hardest part of the job.


Motion Pro T-6 Combo Lever Set: This tire iron set has everything you need, like compact size, a 32mm hex on the lever end, and on the other a combination 10/12mm for rim lock nuts and a 27/22mm adapter included in the kit to tighten and loosen 22 and 27mm axle nuts, in addition to the 32mm size.


Motion Pro Professional Tire Pressure Gauge: When filling tires it’s easy to be off by a few pounds and this is crucial to get correct. I used to use a cheap low pressure gauge but now I use this low pressure gauge. With low accurate low pressure reading and a handy bleeder valve, I feel there is no better tool for this job.





Motorsport Products Tire Changer with Bead Breaker




Our crew always brings tons of fuel, food, brap mix, spark plugs and assorted sundries, but no one seems to have the right sized tube when we need it. It’s up to you to be like a Boy Scout and “Be Prepared” when it comes to tire repairs.


Changing tires while at the track or favorite riding area certainly isn’t as easy as it is in the garage and may take even more time and patience, but once it’s done the fun can resume.


So don’t forget to pack all the tools listed above and also a manual tire pump, duct tape, baby powder, soapy water in a spray bottle, gloves to avoid the scraped knuckles and a good friend to help you.



Bring all your tire gear and even your manual...It may prove invaluable.




One of the ways to avoid repairing flat tires is to prevent them from occurring in the first place and in terms of technology, the standard tire/tube/rim lock setup is growing old quickly…alternatives are available.


One such alternative to the heavy-duty tube is to replace it with a tire mousse designed for Michelin off-road tires, as Michelin is the inventor of the “Bib-Mousse” product. A bib mousse is a foam insert that fills the tire cavity with a semi-solid object (molded foam) that is not susceptible to punctures in any way.


Bib-mousse inserts are a sure way to avoid flat tires, but they come with a hefty price tag (around $125) and are notoriously difficult to install, but offer the ultimate in off-road protection against the dreaded flat tire demon.


Another very innovative tire technology that has gained popularity is the TUbliss tire system. TUbliss states “TUbliss replaces conventional inner tubes with a small red 100 psi insert that creates two different pressure zones inside the tire itself. This enables an incredible 100 PSI of rim protection, increased tire stability and eliminates pinch flats. In turn, this allows you to run very low tire pressure for massive gains in traction and a much plusher ride.” Although a bit complicated to understand and install at first, many riders we spoke to highly recommend it.

In conclusion, getting flat tires is a part of off-road riding, are hard to prevent and can ruin a whole day of riding or racing before it even begins. Being prepared in advance can dramatically reduce the risk of flat tires, but no amount of prep can avoid them completely…so be ready for them!


If you utilize the tools and techniques outlined above, you’ll be able to cut down on the frequency of flat tires as well as being able to get back up and riding in the shortest possible timeframe.

Been running nuetech tubliss for about 6 years now. Absolutely love them. They are one of the first things I put on my bike when it comes home from the dealer. They eliminate pinch flats, which in my 450s was the vast majority of my flats off road. If you do get a hole in the tire, carrying a streetbike plug and co2 kit will get you riding in no time. I also run a tube of slime in each tire to protect against the small pin holes that you get riding in the desert. Another huge benefit is tire changed are insanely fast and easy once you get used to them. No more struggling with trying to force a ultra heavy duty moose tube into a front tire. I have only ever had one tubliss explode on me and it was do to a fault in the first gen design something that Nuetech has fixed.

Remember also, that a 21" front tube will fit in a 18" or 19" rear tire in a pinch. This way, you don't have to carry two different sizes of tubes on the trail. You can at least get back home where you can put the right size tube in.

second the TuBliss post above - I've been running them for a similar length of time and absolutely love them.

I once found two nails in my rear tyre which wouldn't hold pressure, but with the TuBliss inflated, and no air at all in the tyre,  the bike still ran fine - great traction and no wobble. I eventually did a tubeless repair on the tyre, ran the tyre for a few months more then changed it once it had worn out.

One of the best mods I've made on my bikes.

Ran the Nutech's for about 4 years, less flats but still sliced open (beyond plugging) many tires. I ride in nothing but rocks. Last summer,bit the bullet and installed Bib Mousse in both ends.Flat problem solved! Not fun to install or take out, but it's a lot less fun to pay $120 to ride a 2-day dual sport and get a flat within 35 miles on day 1, and within 15 miles on day 2.

Bibs for me for good!

Nothing ruins a day of trail riding like a flat -- with the possible exception of a flat followed by another flat after pinching the new or repaired tube.


I do carry a 21-inch tube (sometimes an 18, too), a couple of irons (the longer, the better, I find), and a CO2 inflator. Just remember, you can be 50 miles from your truck or a source of replacement parts when you lose a tube. 


I originally balked at the Tubliss solution because of its cost, but when you consider that paying a dealer/shop to R&R the tire, replace the tube and possibly balance the assembly is gonna cost 40 bucks or more, I'm thinking it might be cheap insurance.

Check out the tube saddle.  www.tubesaddle.com  It is a cheater setup that is basically a small insert between the tube and the rim that makes it impossible to pinch flat.  Allows to use 8-10 PSI out west in rocks where most require 15-18 PSI.  I have used Mousses, ultra HD tubes, and other "flat preventers" and the tube saddle is far and away the most sano.  No lubes, balls, greases, etc.  Just install and air it up.  Works great.

Great article! The past few years I've messed around with tubes, TUbliss and mousses, eventually settled on the TUbliss and made the video below as I got a lot of questions. I still think the mousses may better suit the serious racer, very aggressive rider, or someone who always rides in very rocky terrain but in most other cases I think the TUbliss is the winner hands down.

For what it's worth, I bought into the 21" spare theory until I actually tried it.  I put a 21 in the 17" rear on my KLR in hopes of getting home after a flat.  Took care to spread the excess length evenly around the tire and to work out any overlaps.  It lasted 50 miles, then split far too badly to patch.  So my experience is it will "get you back home" if you live within a 50 mile radius.  If anyone can tell me what I did wrong, I'd appreciate it.   Meanwhile I'm back to carrying two tubes.

I carry a patch kit. it is much lighter and easier to carry. I have ridden with the patched tires until the tire wears out and never had a patch go bad. I use heavy duty tubes and rarely get flats with 11lbs in the rear and 12lbs in front.

I pump in a couple of shots of slime and run 14 psi. Id say 250lbs with gear. Cant say how effective cause yet to have a flat with this method. Impact hard enough to ding front wheel and when I removed tire there was a small amount of slim between tube and tire but no flat.

I went the other extreme. Was caught with only a 18" tube and needed to repair the front. Stretched it onto the rim and rode for the rest of the day (hard and long)... it was quite OK.


A couple of my regular riding buddies use the Tubeliss system, with limited success. They have experienced a similar amount of failures to the regular tubes guys (but don't consider these flats... just failures - strange).

only words to my knowledge with small wheeled bikes. but i had a 1990 kx80 small wheel that had a flat front tire when i got it. after realizing how sketchy it is to ride with a flat i quickly got to thinking. i was waiting on my buddy to take me to the parts store for a tube when a buddy suggested something that will never go flat. so i had my dad bring me home a full sized pool noodle that you float on home from work. cut it down the middle. stuffed it in. squeezed that tire on. NEVER went flat again. only negatives to it would be cant change psi for on road or off road use. but it worked well. road it hard for 3-4 months before i got rid of the bike. still same noodle . only used it on the front tho.

      Rockstar Energy Husqvarna Factory Racing Rally Star Earns Third Overalll at the 2018 Edition of the Event in Morocco
      April 20, 2018 – (Motor Sports Newswire) – Determined to wrap up his week-long adventure in Morocco on a high, Rockstar Energy Husqvarna Factory Racing’s Pablo Quintanilla has topped the fifth and final stage of the Merzouga Rally to secure a solid third overall in the event’s final overall standings. Continuing to make progress Andrew Short has claimed a spot inside the top 10 in the overall.
      Featuring a mass, motocross-styled start in the dunes of the Merzouga Desert, the fifth and final stage of the event saw Pablo Quintanilla put in a dominant performance. Posting the fastest time for the day, the Chilean rally star solidified his strong third position in the overall standings.
      Putting in his best individual stage performance Rockstar Energy Husqvarna Factory Racing’s Andrew Short crossed the line in eighth position. Wrapping up the Merzouga Rally 10th in the overall, the American is content with the progress he made during the week in Morocco.
      The Rockstar Energy Husqvarna Factory Racing Team will return to action at the third round of the 2018 FIM Cross-Country Rallies World Championship, the Atacama Rally in Chile on August 11/19.
      Pablo Quintanilla: “Today was a really fun stage. We had the motocross start and it was good to battle with the guys from start to finish. I got off to a good start but five or six kilometres into the stage I had a small crash that dropped me back a few positions. Then I had to push until the end and 10km before the finish I got the lead back and was the first to cross the finish line. It felt really nice to win a stage that way. Overall, I’m satisfied with my third position in the overall. This was a tough race with tricky navigation and to be on the podium is always good. We continue to gather experience and look ahead in the races to come.”

      Andrew Short: “I really enjoyed this week in Morocco. Especially this last day was really fun, bringing back memories from my days racing motocross. Before the flag dropped the nerves were there and I was maybe a bit late off the start. It was a good experience racing alongside the fastest guys in the dunes and being able to see their pace. The adrenaline kicked in and I had some really good fun. Overall, the week has been great for me. I enjoy the atmosphere in rally racing and I feel I am improving, getting closer to the top guys. I might still have a long way to go but I understand it needs to be done step-by-step. This week was a positive step in the right direction.”

      Enduro Announcement

      Red Bull KTM Factory Racing are excited to officially unveil their four-rider line-up for this year’s inaugural World Enduro Super Series. Hard enduro specialists Taddy Blazusiak, and Jonny Walker will be joined by classic enduro experts Josep Garcia and Nathan Watson. FMF KTM Factory Racing’s Cody Webb also joins the team.
      The World Enduro Super Series combines a mix of hard enduro, classic enduro as well as cross-country and beach racing events in a seven-round series run over the course of 2018. WESS offers a new challenge to the Red Bull KTM Factory Racing Team and will provide a true test of skill, stamina and adaptability. 

      Opening with the Extreme XL Lagares hard enduro in Portugal on May 11-13, each of KTM’s five official riders will bring their own unique skills set to the new series. All hoping to excel in their specialist events, in the races in which they have less experience the focus is very much on rising to new challenges. Only at the climax of the season will the ‘Ultimate Enduro Champion’ be crowned. 

      Multiple world champion Taddy Blazusiak cites the WESS as the main reason for his return to competition. The Erzbergrodeo winner sees the WESS as a stand-out title he’d like to add to his already glowing CV. Taddy narrowly missed out on claiming a seventh world title at the final round of the 2018 SuperEnduro World Championship and is more fired up than ever to win the World Enduro Super Series. 

      Taddy Blazusiak: “I believe the WESS is what enduro needs at the minute to progress as a sport. I am really excited about the championship and I am really looking forward to the start of it. To be honest, I like every single event on the calendar. They are all unique and very special and from the first to the last race I think it is going to be really good fun. Part of the biggest challenge is going from the SuperEnduro series straight into the outdoor races and then having to adapt to all the different styles of events. My ultimate goal is definitely to do all I can to win the World Enduro Super Series, that’s why I am back racing. I really believe I have a shot at it – I am going to do everything I can to make it happen.”

      Experienced hard enduro rider Jonny Walker is another with his eye on the WESS title. The former Erzberg winner is as at home racing on a beach as he is in extreme conditions. An excellent all-rounder, Jonny is highly-motivated ahead of the new championship start.

      Jonny Walker: “I’m really looking forward to the start of the World Enduro Super Series. It’s a new challenge for everybody and should make for some really good racing. To be honest, I’m not looking forward to just one race either, I’m looking forward to the full series. We have Erzberg and Romaniacs, which I have done before, but there’s also a few races like Le Trefle and the Red Bull Knock Out beach race which pose new challenges. I think to win the series, consistency will be key. I have a lot of learning to do, but my goal is to try and win as many races as possible and hopefully be in a good place come the final rounds of the series.”

      2017 Enduro2 World Champion Josep Garcia has spent the off-season focusing on the WESS and the different styles of riding required to excel in the series. Previously Garcia’s training would consist solely of special test enduro and motocross practice, with hard enduro now added to the Spaniard’s calendar Josep has been spending a lot of time on his KTM 300 EXC TPI, to familiarize himself with terrain synonymous with some of the world’s toughest offroad races. 

      Josep Garcia: “The World Enduro Super Series will be a massive new challenge for me. There are a lot of different races, sand races, extreme and classic enduro. It’s going to be a very interesting year. It will be difficult, but my goal is of course to win. I believe that with the right training and if I can gain some knowledge from my more experienced team-mates, I will be in with a chance. I really enjoy the technical riding and I have been putting a lot of work in. It will be interesting to see if it has all paid off come the first race in Portugal.”

      Nathan Watson’s background in motocross and beach racing sees him as one of the favorites to take the win at the final round of the WESS, the Red Bull Knock Out in the Netherlands. Similar to team-mate Garcia, it will be the hard enduros that pose the biggest challenge to the young Brit. Following two years of riding classic enduro Watson knows where his strengths lie and where he needs to concentrate his training. 

      Nathan Watson: “I’m really excited to be a part of the World Enduro Super Series. It’s going to be a big challenge for all of us as it’s made up of so many different types of enduro. I know the extreme races will be tough for me, I have never done one before but I know what to expect. I have been doing a lot of specialist training, so hopefully it will pay off. Of course, the event I’m looking forward to the most is the final round – the Red Bull Knock Out. I love beach races, I have ridden beach races all my life so I am really confident in the sand and it has to be one of my favorite types of terrain. I think the winner of the whole series will be the rider who makes the most of his strengths, while minimizing his losses – hopefully that can be me.” 

      FMF KTM Factory Racing’s Cody Webb recently added the 2018 SuperEnduro World Championship to his 2017 Endurocross title. On form and ready to take on the WESS challenge, the former trials rider is looking forward to contesting the different styles of events but is aware of the size of the task ahead of him. 

      Cody Webb: “The World Enduro Super Series is a whole new thing and I’m really excited to be a part of it. It’s going to be really crazy doing all these different events, you’ve got classic enduro, extreme, beach races – it’s going to really help me branch out and widen my abilities. With the WESS, there are so many different types of riding, but fortunately riding for KTM, I have got a great choice of machinery for all the different disciplines we will ride during the series. For the extreme stuff I think I will be riding the new KTM 300 EXC TPI 2-stroke, but for the classic enduros I will probably stay on the KTM 350 EXC-F. On the beach I think I will be riding the KTM 450 EXC-F – I’m a decent sized guy so I need all the power I can get. I can’t wait to get started and hopefully by the end of the year I’ll have a chance at taking the title.”

      The first round of the World Enduro Super Series is Extreme XL Lagares, Portugal on May 11-13.

      Hey guys,
      So I picked up a set of DRZ400E rims. I have been looking for ages for a set of these!

      I have an '08 SM model. So luckily these will bolt right on with all the standard DRZ spacers that my SM already has. However, I hear this might require me to interchange my rotor in the front, to a rear SM rotor (front one is way too big for off road according to a few DRZ forums I am part of). The 400SM models front rotor is bolted on though which might make that tricky every time!
      Is anyone riding an SM, who also interchanges to E rims when needed? And what is your setup currently to make the interchange as fast and painless as possible? Including sprocket / chain sizes. I want to be able to change between E and SM standard rims without wanting to Sparta kick my bike over each time!
      PS: On the more social / networking side of things... Subscribe to my new-ish Youtube Channel, JenSM, to watch Cape Town Supermoto adventures (new video is there!). I will also be working on a few other videos that include my Yamaha TDR180 Scrambler rebuild.
      Any other Supermoto Street Legal crews / Supermoto riders / DRZ riders to subscribe to on Youtube, lurking around? Link me to your channels so that I can check your videos out!
