'01 426 and 120 tires....

6 posts in this topic

I've run 120s a lot, I love the width, the handling and the fat float you get....and I have noticed side cleat loss before...but currently I noticed its all on the chain side. My chain (O-ring and new) is adjusted to right in the middle of the factory spec and when I push it towards the tire it actually does hit the side cleats! Is this true? Am I really ruining my tire? Has anyone else seen this before? I guess I got to go back to 110s? :thumbsup:

Adjust your chain, use the tire sidewall as your "gauge" point. Your chain should just clear the side lugs.

Other than the tire it came with all I ever ran on my 426 was 120mm dunlops out back. I never had a clearance problem w/ the chain. It probably rubbed the can and fender a little bit more than a 110...

...I'm not sure if I could have pushed my chain in far enough to contact the tire or not, but I am sure that it never made enough contact w/ knobs on its own to do any visible damage.

Double check your axle/chain alignment as well as tension.

Hope this helps.

Tire pressure is fine, alignment is fine....I'll check the bearings for wheel slop. Maybe keep it on the tight side of the chain tension spec....

By the way, the tire is a Maxxis HT 120/100....the Dunlops I used to have were 120/90. Maybe It's just a little too big?

Thanks for the tips guys!

Could be, I don't know how that brand sizes their tires. One reason I stick w/ Dunlops for rear tires is frustration w/ different sizing of other brands like Michelin & Pirelli. I've been tempted but never have tried a Maxxis.
