Cylinder Airsal Racing Xtreme 78.5cc Derbi Euro 2

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 crankshafts (40mm).
These kits, like the rest of the Extrem range, are equipped with single-ring pistons and a one-piece cylinder head.
The distinguishing difference is that they have two additional boosters apart from the central partition, which makes them a real time bomb.
It is recommended to install a PWK type 28mm carburettor and an exhaust such as Voca Racing Carbono 80cc, Metrakit Pro Race, etc.
