You have to change the rim. A TRX850/FZR600R/FZR400R will fit. I have one ready that I'll put soon.
But you can install a 170/60 rear, I haven't tried it yet but actually it is the proper size for the 5" wide rims.

not worth it you will deform the tyre

Most things done in a hurry need to be done again - patiently.

OMG, thanks for that guys, have been using ones for 20 000 miles now without issues and now I find I need to fit a new rim :eek . The 120 means that you do not run off the edge of the front tyre when you get right over and is safer if anything. Maybe I should go back to a 110 for safety :eek oh you guys make me smile. :evil

Fair enough but still your using a 3.5" tyre on a 3" rim so at best its not got the profile that Bridgestone Michelin etc intended.

And would make any potential insurance claim interesting....
I live in my own little world. But it's ok, they know me here.

Fits quite happily on there and means that you still have tread when the rear runs out, I ride on the front so it's good for me. I expect fitting the occasional 190 on the rear of my other bike instead of the 180 is dodgy too :rollin The profile is slightly pulled but so what, not excessive, not dangerous, helps handling, more rubber on road too. Get a grip for pitys sake. I suppose my Renthalls, bar end mirrors, fazer 1000 rear caliper, disc of a thundercat, screen bolts, perch bolts and so on aren't good as Yamaha didn't fit them, goodness knows about the blue flame and stainless downpipes, and oh god the main stand isn't fitted and the rear is jacked up too. It's a hanging for sure :evil

I did not find anyone which allow what you are doing. 110 on 3.5" are allowed but not the opposite. Anyway I'd stick with the recommended fitting. That is why I will try a 170 rear by the way.

The 190 on the Bird feels much the same as the 180 too. Give it a go, that's how we find what works and doesn't. The 120 works for me. I still prefer the Roadsmarts to the currently fitted 023 especially in the wet.

Also the 160 on the 5" is flattened theoretically, so maybe the bike will have a faster turn in. We'll see...

Not as tenuous as this:

The edge of the rear tyre weared a lot. And there was still more than 1 mm of front tyre unused...

[/quote] that last one 1mm was impossible to reach, the bike was scratching already with the peg a bit folded. I do not see the point of having 10mm, also the lean angle you need to reach them will be crazy, no way the bike can lean so much, you will be scratching the frame first... better put the proper rim. I did not say that almost no free sag is good, I just did it to improve ground clearance. |
