Ysr50 rear sprocket paradox

G-day just a quick question ? I'm doing an engine swap on a ysr50 . The doner motor uses a 520 front sprocket . What 520 rear spockets will match up and have the same bolt pattern as the ysr50 ? Also the doner motor is from an 80 IT125 any info on the motor swap would be beneficial . Thx

Welcome to the forum...

Id would simply use a #420 front sprocket...Its the easiest way......


As far as motor swap..fabricating the lower cradle to work with the engine is the biggest obstacle...

Theres a place called "Team Callimari" who specializes in them...

Good Luck
