RENTHAL - 309--525-15P - Front Sprocket - 15 Tooth - Yamaha
The RENTHAL 309--525-15P 15-tooth countershaft (front) sprocket is built to be the strong link in your drivetrain, with precise tooth form, quality material, and correct dimensional spec. Front sprockets made from case-hardened, core-refined nickel-chrome-molybdenum alloy steel for the ultimate combination of strength and hardness, which is what keeps a chain running quietly and without accelerated wear. CNC-machined (not stamped) and feature a computer-aided ultra-light design to reduce unsprung weight and increase power transfer. Pairing a fresh chain with fresh sprockets is always the right call: a new chain on worn sprockets adapts to worn tooth geometry immediately, shortening both. The 309--525-15P gives you a sprocket worth pairing with a quality chain. Sold individually.
