xUpgrade Your Mini Bike Drivetrain with Confidence
The RZEOZU 50-Tooth Rear Sprocket is designed for riders who push their mini bikes beyond stock performance. Built for 420 chain setups, it complements bikes with a 6-inch rim and a 6-bolt pattern, including popular models like the Coleman CT100U, CC100X, RB100, Baja Doodle Bug DB30, Mega Moto MMB80 and MMB105, as well as Motovox MBX10 and MBX11. This sprocket invites you to explore smoother acceleration and refined torque delivery, especially on modified engines that are 212cc or larger. While results vary by setup, the design emphasizes reliability and efficiency as you ride your daily routes or weekend laps.
Solid Construction and Precision
Crafted from steel for strength and resilience, the sprocket remains sturdier under high-torque riding. The 50-tooth configuration is engineered to create a smoother gear curve, potentially reducing friction during transmission and contributing to longer chain life. While not a guarantee, these design choices can help support consistent performance over time and through varied riding conditions.
