Hi all,

I picked up some rims off of ****, but I noticed the rear is a 18" rather than my stock 19".

I have a 1998 YZ400F. What difference would it make?

Seems that it would change the gearing, I am OK with that, any other reason why to run a smaller rear rim?

Can I lower the forks a bit to 'level' out the bike? will it change the handling?

thanks

Mike

Mike,

The overall tire diameter will be the same, there will just be more sidewall. You won't have to worry about gearing or leveling the bike out.
An 18" rear tire is preferred in most if not all off-road situations.

The main purpose of having an 18 inch rim over the 19 is for trail riding. All full size trail bikes come with them (i.e WR450). This is because with the 18" rim, you use a 110/100/-18 tire. The 100 vs. the 90 is a taller side wall. The outside diameter of the tire is actually aclose to a 19 inch tire. But the reason for the taller sidewall is for more flex when trail riding.

:cool:
