Chain Drive Conversion Kit For Sur-Ron Ultra Bee "Ultra Drive"

Avoid braking your rubber belt drive with the "Ultra Drive" chain drive conversion kit for Sur-Ron Ultra Bee electric dirt bike. Warp 9 Ultra Drive replaces the belt drive system with a much stronger 520 O-Ring chain drive.

Warp 9 Ultra Drive Features

• Final drive ratio is the same as OEM belt drive
• Includes 2 dampened sprockets in EDM coated black steel
• Includes a KMC 520 O-Ring Chain
• 10-12 decibels quieter than other aftermarket 520 O-Ring chain drive kits

The motor and jackshaft sprockets both have rubber dampener rings vulcanized to the sprockets. Before the chain rollers hit the bottom of the sprocket, the inner plates of the chain contact the rubber outer rings. These rubber rings also serve as an additional layer of sound dampening from the steel sprockets. While louder than a belt drive, the Ultra Drive is 10-12 decibels quieter than other aftermarket 520 O-Ring chain drive kits on the market.

*Do not use an impact wrench on sprocket bolts. Hand-tighten sprocket bolts to 8ft lbs.
