Cylinder Airsal Racing Xtreme 78.5cc Derbi Euro 3 / 4

Until now, the Airsal Extrem range for geared mopeds was only available in 45mm stroke.

Unlike the previous kits, these can be installed with original stroke (40mm) crankshafts.

These kits, like the rest of the Extrem range, are equipped with single-ring pistons and one-piece cylinder heads. The distinguishing feature is that they have two additional boosters apart from the central partition, which makes them a true time bomb.

It is recommended to install a 28mm PWK-type carburettor and an exhaust such as Voca Racing Carbono 80cc, Metrakit Pro Race, etc.

ATTENTION! Racing Extrem version for 40 stroke (standard) crankshaft.
