Description
If you’re running a 520 chain on your Yamaha, sprocket wear directly impacts acceleration response and chain longevity. The Renthal 45T rear sprocket delivers a measurable reduction in unsprung weight while its self-cleaning mud grooves eliminate the debris buildup that accelerates premature wear. Built from 7075-T6 aluminum, this sprocket offers the durability you’d expect from steel at a significant weight advantage.
This is a bolt-on replacement that requires no special tools or fabrication—simply swap it in place of your worn sprocket and immediately feel the difference in throttle response and chain engagement.
