yz 125 gearbox

Recommended Posts

The bottom ends are the same from '05+ the only change being the shift stopper lever in 07 so your good if you get an older one.

The only real differences besides that I know of and it's minor is supposively in 2006 cylinder got slightly different porting shapes to go with the CDI's new couple hundred higher RPM rev limiter setting but otherwise everything else has stayed the same.

I believe it read something like this on brochure info, new CDI rev limiter setting now is 200 RPM higher to increase top end power.

I have still have my OEM center clutch hub and pressure plate in very good condition if needed of course I'll trade it for RGV 250 or KR1S parts 👍
