Front sprocket 420 to 520

Recommended Posts

Hi , is there a manufacturer out there that makes a 520 pitch front sprocket for 17mm shaft. I’ve got a custom build going on and I’m trying to figure this out. it’s a Piranha 140 engine that’s why I thought I would post it in the pit bike section.

good job, should work good for you as long as the welds didn't warp anything

I cut the center out of the 420 and welded it to the center of the 520, it’s holding up just fine with 30hrs of ride time on my custom build.
