Amp your ride.

High performance racing sprockets made specifically for use with Motenergy Golden and QS motors. Our sprockets are designed for electric motorcycles and karts that require strong torque, high RPM and fit perfectly with 420, 428 and 520 chain sizes. Every sprocket we make is high quality hardened steel with galvanized coating to resist corrosion. All sprockets come complete with either perfect fit key bars and stainless steel set screws or galvanized C clips. This is what we wanted for our own bikes and now we want to share the love with fellow builders. Please see below for a list of our current sizes.
