Pinasco Cylinder Kit (177.7cc); VNX, Stella 2t

The ONLY aluminum cylinder available for 125/150 engines. Slightly less power than the Polini, but better heat dissipation and more reliable. We highly recommend this kit for daily drivers and touring bikes. 

A Prima pipe is perfect for bringing out the power this kit can generate. Another popular upgrade is a 24/24 or 26/26 carb.

Replacement pistons can be purchased here.

Replacement rings can be purchased here.

Replacement gasket can be purchased here.

***PLEASE NOTE***
Performance upgrades are considered racing parts and are not covered by warranty. There are too many variables involved with user-installed parts, and pushing the limits of your engine tends to wear parts faster. Use at your own risk!

This performance cylinder kit was designed to allow the best cooling characteristics possible. In order to do so, the manufacturer has created a specific layout of the cooling fins. On some applications, the cooling fins at the base of the cylinder come in contact with the flywheel. When this occurs, the fins must be ground off to allow clearance. Removing these fins will not hinder the cooling abilities of the cylinder nor will they subject the cylinder to premature failure. A simple grinding bit will work well for removal.

Caution! When removing excess material, be very cautious. Any damage or modification to the cylinder is the sole responsibility of you, the owner.
