Renthal 13-Tooth Front Sprocket for Kawasaki and Yamaha 252--520-13GP

Chain wear starts at the sprocket, and a worn front sprocket tanks your acceleration and handling before you notice it. The Renthal 13-Tooth Front Sprocket combines case-hardened steel durability with a self-cleaning design that keeps mud and debris from accelerating wear—meaning you get consistent power delivery lap after lap. At 10-15% lighter than OEM, this sprocket also sharpens your bike's throttle response and reduces rotational mass for measurable gains in corner speed.

Built from precision CNC-machined 655M13 nickel chromium steel, this sprocket is engineered to handle the demands of competitive riding and trail abuse. The self-cleaning mud grooves machined into each tooth prevent buildup that would otherwise compromise engagement and accelerate tooth wear. Drop this in place of your stock sprocket and feel the difference in snap and reliability.
