Description
You want to boost engine performance a bit? There's no replacement for displacement, so why not get this Airsal Cylinder 165cc Alu SYM Euro MX 125cc 4-stroke.
It is an aluminium cylinder with bigger bore, meant to be used with the original cylinder head. The kit makes for slightly more power and definitely more torque. To be more specific, the difference will be mostly noticed in better acceleration, better take-offs and slightly higher top speed..
Aluminium cylinders show significantly higher thermal conductivity than cast iron cylinders this means they can withstand much higher performances, plus it makes them less susceptible to piston seizure.

The products listed under Sport yield better performance than Original parts. They may have technical differences, such as the use of higher quality materials, a larger displacement or a performance-enhancing design. They are suitable for everyday use and have a long service life.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
