Works for my1020
Good fit for those my1020 motors. Had an issue with the prior sprocket going bad and this fits the bill so far. Does take a bit of force to get it off and on but ultimately running good so far.

A good bargain.
The sprocket is heavy duty and rugged, and the 4 supplied master link replacements are high quality.

Works but not direct fit
The one that came off my son’s bike is a half moon shaped hole this one is oval so fits loose. And hard to center .. it’s works if you use washers that don’t interfere with the chain and lock the bolt down on it hard .. the lock washer makes the sprocket fit on side ways so I didn’t use my lock washer. My son’s mx250 went about 15mph with an upgraded 350 motor (not controller) now it goes about 20mph. He’s happy with the upgrade .

Perfection
This was used to get more speed out of a 2000w mx350 conversion. It worked well and gave maybe 4 more mph.
