Description

A worn or undersized rear sprocket limits your R1's acceleration and top-end performance. The Sunstar 41T combines aerospace-grade aluminum with precision engineering to deliver stronger chain engagement, reduced unsprung weight, and extended component life—all critical for both street and track applications.

Sunstar's exclusive tooth-valley design increases chain contact area by 50%, meaning more efficient power transfer from engine to wheel with less slippage and wear. The computer-designed weight reduction holes shave unnecessary mass without sacrificing rigidity, improving throttle response and handling dynamics. Hard anodized coating resists corrosion and abrasion, while integrated cleaning grooves keep maintenance straightforward between rides.
