Compared with cylinders made of cast iron, the aluminum cylinder has significantly better heat dissipation meaning the cylinders are less susceptible to wear and piston seizure due to temperature problems.
The Airsal Sport continues its power very early on and has a good increased torque curve.
Carburettor needs to be up-jetted or a larger carburettor should be used.
