Hi All
I was going to replace my rear rim on my 1984 KX250 from the original size 2.15 x 18 and use a 1.85 x 18.
Is there any reason you can't do this?
Thanks Dave

No reason why you can't, but how good an idea it is, mostly depends on the width of the tyre you run.
A 100mm wide tyre really needs to be on a 1.85" rim, or it tends to end up with a square profile and is horrible as you lean it into a corner.
A 120mm wide tyre really needs to be on a 2.15" rim, or it tends to look like a balloon. They often feel squirrelly/wallowy when you're hooking in.
A 110 works pretty well on either width rim, but I prefer them on a 2.15" rim.
