Sur-Ron Ultra Bee Chain Drive Kit | Dampened 520
Sur-Ron Ultra Bee Chain Drive Kit | Dampened 520
STOP BREAKING BELTS. START PUTTING THE POWER DOWN.
Belt failures end rides. This chain conversion swaps your Ultra Bee's primary belt for dampened black steel sprockets and a KMC 520 O-ring chain, with the same final drive ratio as stock.
The Ultra Drive from Warp 9 bonds rubber dampener rings to both the motor and jackshaft sprockets. The chain's inner plates meet the rubber before the rollers seat in the sprocket, which cuts the ringing you get from bare steel sprockets.
Installation note: never use an impact on the sprocket bolts. Hand-tighten, then torque to 8 ft-lbs.

Frequently asked questions
Will it change my gearing?
No. The final drive ratio is the same as the OEM belt drive.
Is a chain louder than the stock belt?
Yes. Any chain drive is louder than a belt. The rubber dampener rings are there to take the edge off the steel-on-steel ring.
Can I use an impact on the sprocket bolts?
No. Hand-tighten them, then torque to 8 ft-lbs.
