Upgrading to a reduction drive makes your rig much handier when you push past stock limits.
- Lower sprocket ratios multiply crankshaft output for faster wheel spin
- Internal oil bath cooling extends service life across weekend track runs
- Universal flange designs adapt to most aftermarket clutch setups
- Tight manufacturing tolerances eliminate play and vibration at high rpms
