Here is the brand new 50cc cylinder from AIRSAL. For the first time AIRSAL is launching into cast iron kits. You should know that a cast iron kit is more solid on long journeys, so it allows additional reliability but it gives a little less power than an aluminum kit.

This model in diameter Ø39.9mm does not hide it, good performance compared to the original. It will certainly be more efficient because it has a very correct finish, work in the channels reviewed and corrected but is above all, a good element to get off to a good start.

It is of course equipped with a piston accompanied by 2 thin segments 1.5mm thick chrome for better torque and sweeping. Attention sold without cylinder head. Clearly it is a very good cylinder, better than the original which will give you reliability and torque without spending too much.
