Malossi Cylinder Kit - Vespa P125 / 150 / Stella (166.6cc)

Has slightly less displacement than the other kits in its class, but don't hold that against it. This cast iron kit gives loads of high RPMs, with out sacrificing much mid and low-range power.

Comes with a cylinder head and the following carb jets:
115 main jet
BE4 atomizer
52/140 idle jet

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. Check our our entire line of Performance Carburetors .

***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!

Replacement pistons can be ordered here:

Looking for more performance upgrades? We also carry a Stella/P125/P150 high performance kit that includes this cylinder!

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.
