Comparing CILOYU Models in This Category
Our selection includes two standout CILOYU sprockets, each optimized for different setups:
- The High Speed 420 Rear Sprocket (40 Tooth, 37mm Bore) is ideal for Coleman CT100U, Baja Doodle Bug DB30, and Motovox MBX10/11. Its wider 420 chain compatibility suits heavier-duty mini bikes tackling rough terrain, providing robust torque without sacrificing speed.
- The #35 Chain Sprocket (40 Tooth) fits Coleman CT100U, Baja DB30, TaoTao GK80, and Predator 79cc-100cc engines. Narrower and lighter, it's perfect for go-karts and lighter mini bikes where agility trumps raw power, offering quick acceleration on flat tracks.
Choose the 420 model if your ride involves more weight or varied surfaces; opt for #35 if prioritizing nimble handling. Both install easily with basic tools, typically in under 30 minutes.
