Take control of your Mini-Moto’s power delivery with the Driven Racing EVO TECH Front Sprocket. Engineered using proprietary EST Technology, this is one of the lightest 428-pitch steel sprockets on the market. Whether you're looking for wheelie-popping torque or smoother highway cruising, these sprockets are the gold standard for Honda 125cc builds.
CRITICAL NOTE: This is a 428-pitch sprocket. It will NOT work with your stock 420 chain. This is intended for 428 chain conversion kits.
Gearing Cheat Sheet: • 13T (Best Acceleration): Maximum torque for wheelies and short tracks. Top speed limited to ~65mph. • 14T (Improved Snap): The "sweet spot" for most riders. Better acceleration with minimal top-speed loss. • 15T (Stock Ratio): Best for big-bore kits or riders looking for lower cruising RPMs.
Note: 1 tooth down on the front is roughly equivalent to adding 3 teeth to the rear sprocket. Orientation matters—install with the laser-etched logo facing outward.
