Supermoto chain rub

Recommended Posts

Looking to install a 4.25" rear excel/talon supermoto wheel to my 2014 CRF 450X. I have been reading a lot about the chain rubbing on the tyre. How can I stop this, looking for easy fixes.

 

What tyre would be best as have read that different brands of tyre will come up different widths?

 

Will running a did vt2 narrow chain help?

 

Any spacers available that can offset the front and rear sprockets?

 

I dont want to start messin with the spokes and off setting the rim as some do or shaving the tyre.

 

Help would be much appreciated..

I bought a chain block off him & they work great

VT2 chain = yes

I am also running a 4.25" rear wheel, No offset on the sprockets or wheel / spokes, My chain sits a few mm off the tyre & there is no sign of it hitting the tyre at all with the chain block doing its job nicely

Some reading for ya>

Thanks for your reply. Have mailed the guy about the chain block.

 

Was wondering what tyre you use on the back. Have read that tyres come in different widths and some cause the rub. Read that even a 150 rear for example will still be slightly different due to whatever brand of tyre chosen?

I am running Pirelli Diablo Rosso II 120/70-17 front & 150/60-17 rear, Nice sticky tyres that offer plenty of milage too

The 150 is the typical size to run on the 4.25" wheel & the 160 is more suited to the 5" wheel, I dont know why people go to all the trouble of squeezing in a tire that is 10mm wider (varies depending on brand), Its not worth the hassle unless you are racing maybe?

I'm running conti sport attacks. I'll look to see what size when I get home from work. 25 psi has been a good number for me. At 30 psi I found the limit on traction more than I'd like.

I think guys want the 5" rim so they have more choices for slicks.

I run a 160 and it rubs. run a 150 and youll be fine. Even with the 160 it just rubbed its own groove in the tire, no worries there.
