Fits tightly on the moter, works great.

As described. Gained a 5 mile per hour boost on my 60v 2500w Razor MX650’s MY1020 Motor from swapping the old 11 tooth to this 13 tooth, but sacrificed a small bit of torque. Definitely worth it. Installation was super simple and easy and took me like two minutes. Fits stock chain and tensioner without modifying.
