Description
A worn or stock front sprocket directly impacts your Yamaha’s acceleration, chain life, and overall drivetrain efficiency. The Renthal 13T 520 sprocket combines precision engineering with lightweight construction to deliver measurable gains in throttle response and reduced unsprung weight. If you’re running hard on the track or trail, upgrading to a Renthal sprocket means fewer maintenance intervals and more consistent power delivery through every gear.
Built from case-hardened 655M13 nickel-chromium steel, this sprocket resists wear far longer than OEM alternatives while the self-cleaning mud grooves actively shed debris during operation. The CNC-machined tolerances ensure perfect chain engagement, and the 10–15% weight reduction improves both handling and acceleration without sacrificing durability.
