Also are the drive trains similar to the buggy

I'm pretty sure the M2 type J uses 33T diff pulleys which are compatible with the '94 YZ10 and Pavidis editions. The main commonality between the YR4 and YZ10 is in the drivetrain (layshaft, diff pulleys, bulkheads), although I do not know with certainty which YR4 model began the switch from 35T pulleys to 33T pulleys.

where to begin? some early yr4's had ridiculously thin chassis's. then there's the bulkheads, outdrives, belts, center bulkheads, shock towers, top plates, belt tensioners, shocks, carriers, spindles, etc... it was an interesting evolution for the yr4. try out this site. it's not complete, but it gives you an idea what the parts went through and the changes.

Have a question,so the bulkhead of a yr4 m2 would fit a yrm4 right?

Am i correct to assume this?

i'm not sure what you're asking, but check out page 7 in the PRO manual. that should give you an idea what it looks like...

thanks for the link, seems they are the same, maybe just the kickup degree.

Hi Guys,

need your help again, need to confirm if the swing shaft (universal) for the YR4 front and rear are the same length? meaning I can use either front to rear and VV?

will the ZR 010H fit the YR4 Front?or rear?



ZR-010
