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.
