Biggest f'n knobs ever...

Recommended Posts

I just bought an IRC M5B for the back of the CRF. I couldnt get a Maxxis in a resonable amount of time, they're back ordered till 11-1.

Anyway, this IRC has the biggest knobs Ive ever seen on a motorcycle tire. If there is such a thing as an envior-friendly tire, this thing is its evil twin :cry:

I just measured the knob hieght. 3/4" In print it doesnt sound like much. Go throw a scale on the rear tire of your bike and think about it...The thing is crazy looking...

I used to run those all the time years ago. They do have some huge knobs don't they?

When I was racing hare scrambles I would take the edge off them before a race because the bike hooked up so good it would just wheelie everywhere.

They were a little scary in the rocks though.

You have discovered the tire. The 140-80-18 of the M5B + my old CR meant the people behind me are in serious danger during a throttle opening on a rocky trail. As has been said, it may be the most effective weapon us PNWers have against all the mud. Spread one out on a wide rim and they last forever too. I hear they may be a little squirly at high speeds but I wouldn't know since I always gear everything way down for the mountainous terrain around here.

I read somewhere the AMA limit on knob height is 3/4".

Check out a Tera-Flex tire if you want to see huge knobs. It's probably the heaviest off road motorcycle tire made in its class. If too much rotational mass is a concern, stay away from this tire. You don't want to ride behind a powerful bike sporting this tire unless you're wearing your armor.

Where did you order it from, every IRC tire I have ever seen is super expensive. My buddies all run Cheng Shin c755's and swear by them. They have some nasty knobs on them too.

This thing dwarfs my Maxxis. It also dwarfs the C755 (530-18) Cheng shin on the spare wheel for my CR500 too.

At first I wasnt too thrilled with it. I had 14 psi in it and it was squirrelly like you cant believe. I dropped the pressure to 8 and it was a lot better. I can see it working in super sandy or loose conditions, but I guess it works ok on more normal stuff too.

I got it off the shelf of the shop around the corner from my house. It'd been on the shelf for at least 3 years :cry:

Ive got two wheels. I guess I'll use it for a practice and general use tire. When I get some more cashola, Im going to pick up a 756RR for races only...

      I just bought a Magura hydraulic clutch for my 2014 CRF450R.  Bought it thinking install would be easy, and I'm not sure that's the case now that I have the product in my hands.  I have searched the forums, YouTube, etc for install help specifically for my model year (2013 and 2014 are same really), and haven't found anything specific for the 2013-2014 model install at all.  Instructions from Magura are TERRIBLE, and are not specific at all to the Honda - generic instructions - so I'm debating if I want to return the product, cuz I don't want trouble or a big install job.  Question: for the 2013-2014 CRF450R install ONLY of a Magura Hymec hydraulic clutch - other model years are different and thus it won't be helpful for other model years - do you have any tips or feedback?  My concerns are below...
      1.  The 2014 model has a sleeve behind the clutch actuation arm that the Magura clutch slave cylinder fits into.  Stock, the sleeve holds one end of the cable, with a nut on the other end to keep the cable end tight in the sleeve.  The Magura slave cylinder, however, slides into the mounting sleeve  - but does NOT have a nut: the tension from the clutch actuation arm pulling on the metal Magura slave cyl tip end is apparently supposed to keep the Magura slave cylinder tight in the mounting sleeve.  Q: Will the Magura slave fit in to the mounting sleeve easily, stay tight, and is there any adjustment needed in order to keep the 4-6mm of freeplay that Magura recommends?  How easy is it to get the Magura slave fitted into the sleeve and the metal tip in place?  Is there enough freeplay between slave and tip end to mount in actuating arm AND the holding sleeve, so that the holding sleeve doesn't need to be unbolted?  
      2. The stock clutch cable and OEM setup runs out of the mounting sleeve (see pics marked "metal starts", and then runs through a metal sleeve that routes the cable through the engine compartment - keeping the cable away from the hot parts of the engine case, so as not to melt the cable insulation (I believe).  That metal sleeve is about 6-8 inches in length.  The Magura clutch cable, on the other hand, exits the Magura slave cylinder at an angle - yet has no such metal routing.  I don't think the OEM metal routing sleeve will accept the Magura cable either, so a) the OEM metal routing sleeve would have to be removed first before installing the Magura - and then b) you have to hope that the Magura cable can be routed in such a way with zip ties holding the hydraulic line that line will not touch or be close to the hot metal engine casing as you route it through the engine.  Q: how easy was it to get the OEM clutch cable and metal routing sleeve out?  Easy as unscrewing the nut on the other end of the OEM cable, on the other side of the black rubber cable flange in my pics?   
      3.  My stock clutch pull isn't bad.  I just like the feel of a hydro clutch.  Any feedback on how much better feeling and easier pull will be with the Magura?  What's your feedback on the difference?  FYI, I'm leaving my clutch plates and springs stock.

      We have a 2016 CRF450R with about 11 hours out. never ridden hard always check the oil and change when needed along with the air filter. Took care of the recall that was required as well. Well when riding the bike was stalled out. Went to try and kick start the bike again. the kick start lever just back up jamming my knee into the handle bars and some how ended up cracking the case right by where the kick start goes through the case. Has any one had this happen or heard of this happening? What is the cause?

      Any advice on what should be replaced while I have the top end off for a valve replacement. Will do headgasket and springs of course, anything other parts you would recommend while I'm going at it?
       
      Thanks!

      The dirtbike is on it's forth year right now on the same motor job. I have to jump start it. Is it worth me trading for a 2009 650 brute force with7000 miles? Need some expert advice. Thanks

      Just wondering what you guys do to remove black marks on your seat. My 08 crf450r has the red/black seat, and after each ride there are some black marks on the red from my riding pants. Not scuff marks, more like patches of black residue from my pants rubbing on the seat. I’ve tried the magic eraser which seemed to do the trick, but lately they seem like they aren’t coming off. Also tried scrubbing bubbles with a brush and no luck. Not too worried cuz I have an spare OEM seat, but I’d like to keep this one nice. Any ideas? Maybe I shouldn’t wear black pants?
