PBR Twin Color Ultra-Light Mud-Resistant Hard Anodized Aluminum Sprocket 899 51 TC6 — 520 sprocket designed for demanding riders in motocross, MX, SX, and roadster applications seeking lightweight and reliability in muddy terrains.
Designed for both competition and road use, this PBR sprocket combines precise machining and surface treatments tailored to the demands of motorcycle transmissions. Its design promotes better chain feed in muddy conditions and reduces weight at the rear wheel, which is felt at the handlebars during throttle changes and acceleration. Compatible with machines such as KTM 690 SMC R, STARK FUTURE VARG EX, or HUSQVARNA FE 501 (check for fitment on your model), it integrates seamlessly on both aggressive roadsters and off-road machines.
