Designed to provide a quieter riding experience without compromising performance, the BBR Tuning 2-Stroke T Belt Drive Transmission Kit is perfect for those looking to take their engine to the next level.

Most 2-stroke engines on the market today use a chain drive to get you where you need to go. Although effective, the end result is a drivetrain that is noisy, difficult to maintain, and a riding experience that is simply not comfortable. The BBR Tuning 2-Stroke T Belt Drive Transmission Kit however uses two machined aluminum gears and a belt in lieu of a chain. This enhancement allows for a near silent drivetrain, simple and straight forward maintenance, and a ride that will feel smooth.

Engineered with versatility in mind, this kit is compatible with a wide variety of 2-stroke engines and bike builds. Featuring a 6-hole and 9-hole rear gear configuration, you can utilize this kit with either a sprocket clamp assembly or mag wheel setup. It is even compatible with both 48cc and 66cc/80cc 2-stroke engines alike. Not to mention installation is a breeze, all you need to do is:

  1. Remove your 10-tooth sprocket using a sprocket removal tool and replace it with the small drive gear included in the kit.
  2. Install the larger drive gear to either your sprocket clamp assembly or mag wheel.
  3. Replace your existing nylon pulley wheel with the upgraded aluminum wheel provided.
  4. Install and align the T-Belt provided in the kit.

So, ditch your clunky chain drive and get the BBR Tuning 2-Stroke T Belt Drive Transmission Kit for the smooth and quiet ride you want and engine efficiency you deserve.
