Description
A lightweight rear sprocket is fundamental to unlocking better acceleration and throttle response on your Yamaha. The Renthal 51T trades unnecessary weight for CNC-machined precision, delivering measurable gains in both performance and durability without compromise. If you’re serious about maximizing your bike’s potential—whether on track or trail—this 7075-T6 aluminum upgrade belongs on your build list.
Renthal’s self-cleaning mud grooves are engineered to shed debris and reduce wear, keeping your drivetrain running cleaner for longer intervals between maintenance. At 66% lighter than steel, this sprocket improves rotational inertia, giving you quicker power delivery and more responsive handling in demanding conditions. The corrosion-resistant blue finish ensures your investment holds up through harsh environments while maintaining that factory-quality look.
