JT Sprockets RaceLite Rear Sprocket (50T / Black) JTA895.50BLK - KTM / Husqvarna 2004-2023

Product Description

The JT Sprockets RaceLite rear sprocket delivers exceptional power transfer and rotating weight reduction for competitive riders on KTM and Husqvarna mini machines. Precision-engineered from aviation-grade Ergal 7075-T6 aluminum, this 50-tooth rear sprocket is built specifically to meet the grueling demands of closed-course motocross racing.

Each sprocket is manufactured using CNC machining and advanced laser cutting to maintain exact tooth profiles for size 428 drive chains. The aluminum is fully heat-treated and bead-blasted to reduce surface tension before receiving an anodized black finish, yielding maximum strength and wear resistance with minimal un-sprung weight at the rear hub.

A: It is constructed from aviation-grade Ergal 7075-T6 aluminum and finished in black anodizing.

Expert Pro-Tip: Never reuse old sprocket bolts when installing an aluminum rear sprocket. Always install new thread-locked bolts and flanged Fuji locknuts, tightening them in a cross-pattern to the exact manufacturer torque specification. Inspect your chain tension and ensure your 428 chain is not stretched or worn, as a worn chain will quickly cup and destroy new aluminum sprocket teeth.
