ProTaper Sprockets

ProTaper Race-Spec Sprockets for Motocross & Off-Road

ProTaper has been a cornerstone of the powersports world since 1991, and that same engineering DNA that revolutionized off-road handlebars runs straight through their sprocket lineup. Whether you're lining up on a supercross track or tackling a brutal enduro course, ProTaper sprockets are engineered to handle the punishment that separates race-worthy hardware from the rest of the shelf.

Front Sprockets Built for Punishment

ProTaper's MX front (countershaft) sprockets are manufactured from case-hardened chromoly steel — a material choice that maximizes toughness at the contact points that take the most abuse. Each sprocket is precision broached and machined to strict tolerances, and strategically placed lightening holes keep rotating mass low without sacrificing structural integrity. Self-cleaning mud grooves prevent dirt and debris from packing between the teeth, a feature that pays dividends in lap times when conditions get sloppy. A special coating rounds out the package by aiding wear resistance over the long haul. Teeth counts are laser-etched directly onto the sprocket for quick, at-a-glance identification during race prep or maintenance.

Race Spec (RS) Rear Sprockets — The Engineering Difference

The crown jewel of ProTaper's sprocket range is the Race Spec (RS) rear sprocket. Machined from 7075-T6 heat-treated aluminum, these sprockets strike the ideal balance between weight savings and load-bearing capacity. What truly sets the RS design apart is ProTaper's proprietary angled mud groove technology: the grooves are CNC machined in the opposite direction of the load-bearing teeth, which maximizes the tooth surface area that the chain actually contacts. The result is a design that delivers 44% more tooth surface area compared to traditional sprocket designs, translating directly into measurably longer sprocket life. The angled grooves also allow the sprocket to self-clean during operation, preventing the dirt buildup that leads to horsepower loss and accelerated wear. A deep-penetrating anodized finish protects the aluminum substrate, and laser-etched tooth counts make gearing swaps fast and foolproof.

Broad Fitment Coverage

ProTaper sprockets are available for the vast majority of dirt bike makes and models, covering popular platforms from Honda, Yamaha, Kawasaki, Suzuki, KTM, and more. With over 200 sprocket SKUs available, finding the right front or rear sprocket — or pairing both into a complete drive overhaul — is straightforward for bikes across a wide range of displacements and model years.

Why ProTaper Sprockets Stand Out

• Proprietary mud groove geometry delivers 44% more tooth-to-chain contact surface area vs. conventional designs
• 7075-T6 aluminum rear sprockets balance light weight with high tensile strength
• Case-hardened chromoly steel front sprockets for maximum durability under hard acceleration
• Self-cleaning design prevents performance-robbing dirt and mud buildup
• Race-proven by championship-winning riders and factory-supported teams across motocross and supercross
• Deep-penetrating anodized finish for corrosion resistance and long-term aesthetics
• Laser-etched tooth counts for quick identification in the pits
