Description
Rear sprocket wear directly impacts acceleration, chain longevity, and overall drivetrain efficiency—making a quality replacement essential for serious riders. The Renthal 45-tooth aluminum sprocket delivers the lightweight performance and self-cleaning design that off-road and dual-sport riders demand, without sacrificing durability. Whether you’re pushing through mud, navigating technical terrain, or logging miles on adventure routes, this sprocket keeps power flowing consistently while reducing unsprung weight.
Built from CNC-machined 7075-T6 aluminum, this sprocket is engineered to handle the demands of Kawasaki’s most capable machines. The self-cleaning mud grooves at each tooth prevent debris accumulation that causes chain slip and accelerated wear, while the hard-anodized finish resists corrosion in harsh riding conditions. At 66% lighter than steel alternatives, you’ll notice immediate improvements in throttle response and bike agility.
