USED BIKES: The best answer for riding fever



Looking to buy a used dirt bike? If so, read on because we’re going to give you some solid advice on how not to get burned in the process. Years of experience coupled with some expert advice from our industry sources provide a step-by-step guide to buying that pre-owned bike of your dreams.

Buying used recreational toys like dirt bikes are among the best values in motorcycling today. Historically, off-road motorcycles endure huge monetary depreciation and other factors such as rider attrition and economic hardship helping expanding that vast pool of used machines available… when people need to pay the bills, motorcycles are among the first items to go.

With that in mind, not all the deals out there are good ones. Many unscrupulous sellers are just waiting to steal your hard earned cash in trade for a good looking piece of junk. Let’s look at how to avoid many of those pitfalls that await you as a prospective buyer.


Cash is king and going to see bikes that you expect to low-ball the sellers by vast margins is unrealistic and a waste of time for everyone involved. Know what you have to spend, have it ready in cash when you leave the house.


Determine what kind of bike you want. This choice should be based solely on the kind of riding you actually do, not what you see Ryan Villopoto and Kailub Russell do because you aren’t that good (yet). So if you ride motocross, get a moto specific ride, if you ride enduro/woods, look for a good woods mount. They’re worlds apart and you’ll need the right tool for the job.

Next is the 2-stroke versus 4-stroke question, one of the most hotly debated subjects in our sport today. Let’s try to objectively examine a few pros and cons of each when buying a used machine. It’s my personal opinion that to be competitive in the two larger MX and SX classes, a 4-stroke is required to be part of the mix, so with that said;

2-Stroke Pros

  • Low cost of entry
  • Easy and inexpensive to rebuild

2-Stroke Cons

  • Less manufacturers support
  • Rebuild more often

4-Stroke Pros

  • Easier to ride fast
  • More usable torque at all RPM’s

4-Stroke Cons

  • Heavier
  • More expensive to rebuild


Bring a friend who rides regularly, knows off road bikes backwards and forwards and bring them with you. Discuss what you’re looking for and have them look at the prospective purchases, whether on eBay, CraigsList, ThumperTalk Classifieds, or whatever. Always demand recent photos of the bike and don’t accept dark, cloudy photos as a reason to drive 40 miles to see an old junker - gas is expensive these days last time we looked.


Just because the bike looks good (new plastic is cheap) or is amazingly cheap, don’t believe a bit of what you read. Talk (and words) are cheap so make sure you go into every deal as a skeptic and remember that emotion plays a huge role in impulse buying. Don’t be a sucker and jump at the first thing you see. In our experience, this is a rookie mistake and can have big consequences.


When making a time to see your prospective purchase, make sure you stick to what you say and if you’re going to be late or not show, call the seller and tell them! Being late, being rude and making disparaging remarks about the bike to the seller almost always results in a less than friendly dialogue and usually results in you paying a higher price…being polite costs you nothing and could result in a better result at the end of the deal.


We like to meet buyers at their home garage or workshop to see the general state of their mechanical abilities. Does the seller have other machines and are they in good working order? Is the garage/work area clean and free of old broken parts and such? Are there maintenance items like oils, lubes, and sparkplugs in sight? Just remember, this is where your prospective purchase was maintained…is it up to your standards?


It doesn’t cost anything to ask the hard questions that can help determine the true condition of the bike and things you may need to pay attention to right away. Here are some sample questions to ask:

  • Any problems at all?
  • How often is it ridden?
  • Has it been raced?
  • How often do you change the oil and air filter?
  • Has it sustained any major damage or repairs?
  • Are there any aftermarket parts and are the stock parts still with the bike?
  • Does the seller have the title and bill of sale ready for transfer?

Regarding race bikes versus all others, our friends at Cycle Trader said “The old myth that buying a race bike is just a myth…would you prefer the practice bike that never had the oil changed, or the farmers kids bike that was left out in the rain, your choice!” “If you find a true race bike, it will have been maintained better than any other, as it is important that it finished the race. But still the question needs to be asked, why are they getting rid of it?”



Make sure you and your moto-buddy test as many things on the bike as possible such as engine, suspension, bearings, fork seals, etc. Many of these tests can be performed in a stationary situation, but being able to start and actually test ride the bike makes a world of difference.

On motorcycles, cylinder compression is king. If the bike won’t start due to low compression then you’ll most likely need to rebuild the engine before actually having fun with it. If it doesn’t pass either one of these standards, you’ll probably want to walk away as running bikes in decent shape aren’t that hard to find, so why settle for junk?

On 2-strokes this is easy to test and experienced riders can tell with a few kicks whether the bike will reliably start and has decent compression.

On 4-strokes it’s a whole different ball game as many factors effect the compression cycle, not just the rings. Factor in valves, cam, cam chain, etc. and it can be a lot of expense and labor…so how can you avoid this?

Bring a compression leakdown tester, that’s a good start, and you can buy one from MotionPro for around $150. All engines have different cylinder pressure figures, but most engines fall in the 110 to 190 PSI range. Components that wear over time like rings, valve seals, and cylinders can cause huge problems and engines that exhibit low compression should be left for some other unlucky buyer.

Here are some key items to inspect when looking at a used bike:

Suspension: Inspect fork seals for leaks, check rear shock for same. Inspect steering bearings and swingarm bearings by putting the bike up on a stand to test that the suspension moves thorough its travel with almost no clunking or squeaking noises noise(s).

Frame: Visually inspect the frame for any cracks, welds, or bent areas. Look carefully at frame cradle area for deformation.

Brakes: Inspect discs for gouging and cracking and check for correct fluid level at master and slave cylinders on bikes equipped as such. Check for proper pressure at lever and let off, then check if the brakes drag or make any bad noises due to warped disc, worn pads, etc.

Clutch: Pulling the clutch cover and inspecting the basket for chopped sides, and the plates for their thickness, is another common thing to check as a clutch setup can easily cost you $400.

Spokes: Most people over tighten spokes, and this causes them to stretch and become weak. Unscrew a spoke and see how far the threads go through the rim, at some point they will start poking through the rim strap, and you will see a lot of flat tires. It’s also a safety concern. Replacing spokes is not difficult, you can do it yourself one at a time once the tire is off.

General Maintenance: Check for a clean air filter, fresh gear oil and decent tires. Check both sprockets and the chain for excessive wear, pull the spark plug and see what it looks like. Refer to our previous spark plug chart to see what’s been going on in the cylinder while the bike was running. Is the bike straight? Are the bars/levers bent? Inspect the heads of the screws and bolts…are they in good shape?

Our experience has been that lazy riders don’t maintain their bikes and if it looks bad on the outside, just imagine the work the seller may have messed up on the inside?

Some other tools to bring include a small, bright flashlight, spark plug wrench, some rubber gloves and a bike stand so you can inspect items like fork seals and bearing play. And don’t forget a truck/van/trailer in case you actually do buy the bike right then and there.


Every seller expects you to negotiate the price, unless it says “firm”, but don’t go into any deal thinking you’ll get something for half of what someone is asking. Normally, sellers who discount at this level are selling junk and it’s worthless to begin with. It’s normal to try to get up to 30% off the asking price when it comes to recreational toys like motorcycles.


Now is the right time to sit with the owner and ask for the title and bill of sale. In our experience, buying bikes without titles is a sure way to get some stolen product. Make sure to ask for the driver’s license of the seller and take down that information, checking that it matches the title and VIN number on the frame.

If you purchase a stolen bike without doing due diligence, you will have to give it back to the rightful owner and you will lose your money…and you may be charged with receiving stolen goods too!


After the deal is done, don’t forget to ask for and collect any parts or accessories/riding gear you may have purchased with the bike.

Find a CR500 and you will learn the true meaning of torque and power at all rpms.

Along with the true meaning of 'OH SH*T IM GONNA DIE!!!!!!!' hahaha

The same can be said of my KDX200. I think a lot of two-stroke trail riders are going to call BS on "More usable torque at all RPM’s" being exclusive to four-strokes.

Yeah and that CR500 will cost you pennies compared to a new fangled showroom queen!


Not saying I could ride one but someone would love to...

"In our experience, buying bikes without titles is a sure way to get some stolen product."

Of all the "not in my experience" statements made in this article, this one is the least informed.  Many states do not require a title on off-road vehicles.  Please do some research before telling people in all 50 states about YOUR experience in YOUR state.


"Clutch: Pulling the clutch cover and inspecting the basket for chopped sides, and the plates for their thickness, is another common thing to check as a clutch setup can easily cost you $400."

How many times have YOU actually taken the clutch cover off someone else's bike to look at clutch parts and took a chance on that ~ $10 gasket breaking?  Would YOU let someone take the clutch cover off YOUR used bike for sale??  I would say it is not common, as you stated.

      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.

      Awesome hard enduro machine, but also fast enough to push your eyeballs back

      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!
