It's made to match common mini-bike models (including several Doodlebug-style and Motovox machines) and to deliver smoother power transfer while resisting premature wear when installed and maintained correctly.\u003c\/p\u003e\n\n\u003ch3\u003eWill this sprocket fit my Coleman CT100U or similar mini bike?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the sprocket is engineered to the same mounting measurements used on many small-frame mini bikes.
