Cyl.Airsal 70cc Sport
With the Airsal 70cc, you get an aluminium cylinder for the same price as a common cast-iron cylinder. It has a hardened chrome-nikasil bore and due to the fact that it is made of aluminium, it can shift heat much more efficiently than the cast-iron version and piston seizures are a lot less common. Unfortunately, high top speeds and huge hp's are not the strong points of the Airsal cylinder. However, it has an even torque development and high power at low revs, which can be interesting for some drivers. Works fine with original and touring exhaust systems.
Comes without cylinder head, you will have to go on using the original one!
