03 kx125 roller

is the bottom roller on an 03 kx125 40mm?

Uhh... what do you mean by bottom roller?

Chain roller. :p

Oohhh... lol

Well in that case... 40mm is huge lol, almost fork tube size..

Pretty sure they are 32/34 mm --

I just replaced them on my 03 KX250 -- the rollers are the same part number on 125 vs 250.

Moose Racing part number M795-00 - $14.95 here at Thumpertalk.
