Chuck - MORE Power and durability

Our "CHUCK" set is a empowerment of the Rotax engine in your Ski-Doo. The nickel plating increases the corrosion resistance of the cylinder.

Unlike the OEM parts, BBB uses a nickel plating - Nikasil (Mahle trademark) and Gilnisil (Gilardoni trademark). This plating is used in most high performance two-stroke engines for many years. Tripple BBB is combining the best of two worlds:
Nickel plated bore as state of the art technology with the robust crank train from Rotax.

Increase to a nice 84 mm bore!
The extra kick of power you need to upgrade your 850 to a 900 class.
