Renthal Front Sprocket 13-Tooth 520 Chain Kawasaki Yamaha 289--520-13GP

A lightweight front sprocket is one of the quickest ways to sharpen your motorcycle's throttle response and reduce unsprung weight—both critical factors in acceleration and handling. The Renthal 13-tooth sprocket delivers measurable performance gains through precision engineering and material science, without requiring any modifications to your existing drivetrain. If you're running a Kawasaki or Yamaha and want noticeable improvements in low-end responsiveness, this is a straightforward bolt-on upgrade that pays dividends on the track or trail.

Built from case-hardened 655M13 nickel-chromium steel, this sprocket resists wear and maintains tooth integrity through extended use—essential when you're pushing your bike hard. The self-cleaning mud grooves prevent buildup that can compromise chain engagement, while the ultralight construction shaves 10-15% off the weight of standard OEM sprockets. Every gram matters when you're optimizing performance.
