428 Chain 15 Tooth Front Sprocket with 20mm Bore

This 428 pitch 15 tooth front sprocket is designed for pit bikes, dirt bikes, and youth ATVs using small engine powersports setups. Built from durable steel, it delivers long wear, smooth power transfer, and reliable performance in both recreational and performance riding.

The 20mm bore fits many popular Honda, Lifan, and Chinese engine platforms including 110cc, 125cc, and 140cc models. Bolt hole spacing measures 34mm center to center for secure mounting and proper alignment with standard 428 chain systems.
