ok ive heard rumors u can mount up a 180 55 on the rear of a f2 with no modification?? who can verify this. before i buy a new tire for no reason! thanks

 

I run it on mine with no issues

 

Even if it fit without rubbing the chain (I don't know if it would or not), I would NOT recommend it on the stock rim. Its far too narrow for that wide of a tire. The tread profile will be pinched and the tire won't handle (lean in) as it was designed.

 

i wouldnt try it with an f2 rim... it would fit but the tire would be out of shape... i would upgrade the rim to an f3 rim so it spreads out wider especially with the chain

 

The F3 rim still isn't as wide as a rim should be for a 180 tire. But it will be closer.

For anyone that's done it: Does the F3 rim retain the same sprocket location? i.e. are their any alignment issues between the front and rear sprockets?

 

yea it still retains the same sprocket location... same distance across with the bearings

 

Okay, cool. good to know

 

I have no wear issues, bead issues, rubbing issues or performance issues. I can lean the bike over more then my buddies with stock size tires on their sv650 (160) and triumph tripple (180). The only issues I have is the tire likes to slide because its a hard compound tire. But its the only tire I had to put on at tthe time. no regrets
