Key Features

  • Maximum Speed Optimization: The 17-tooth design is the ultimate "high-speed" configuration for 420-chain systems, significantly increasing top speed while allowing the engine to run at lower, more comfortable RPMs.
  • Precision Polished Teeth: Gears are precision-machined and polished to ensure a perfect, seamless connection with the chain, effectively eliminating slippage and reducing mechanical drag.
  • High-Strength Alloy Steel: Forged from premium alloy steel, this sprocket is built to withstand extreme torque and abrasive off-road conditions without compromising its structural integrity.
  • Whisper-Quiet Operation: The precise internal tooth geometry ensures tighter meshing between the gear and chain, which drastically reduces drivetrain noise and vibration for a better handling feel.
  • Exceptional Wear Resistance: Engineered with advanced corrosion and wear resistance, this sprocket is designed to work stably under extreme loads, extending the life of your entire drive system.
