ProTaper Front Sprocket Yamaha Sprockets

ProTaper Race Spec (RS) front sprockets for Yamaha are replacement countershaft sprockets for motocross, off-road and powersports drivetrains that see hard use. Each one is CNC machined and internally broached to precise tolerances. They are made from case-hardened, core-refined chromoly steel for strength and long service life.

Key Features:

• Chromoly steel construction: Case-hardened, core-refined alloy steel gives a strong tooth root and good durability.
• Precision machining: CNC machining and internal broaching hold tight tolerances for an accurate fit on the countershaft.
• Computer-engineered design: The tooth profile and balance are designed to reduce chain drag and carry power to the rear wheel.
• Weight savings: Lightening holes reduce rotating weight.
• Self-cleaning mud grooves: The grooves help prevent dirt buildup.
• Protective coating: A specially formulated coating helps resist wear and corrosion.

Whether you want sharper acceleration or a more durable replacement for a worn stock front sprocket, ProTaper sprockets are built to hold up to hard riding. Choose the tooth count that suits your gearing needs from the available options in this product line.
