Cylinder kit Airsal Xtrem 88cc. This is a worst cylinder with the whole 88.30cc from Airsal.
The cylinder is one of the most powerful on the market and well worked out and qualitative.
The piston included is made by Vertex and has a piston ring.
The exhaust port is oval and two-piece.
The cylinder is also nicely painted in red.
Just like Malossi Big Bore cylinders, Airsal Xtrem must also be used with a crank that has a 45mm stroke, which is of course available in Airsal's range.
In order for the cylinder to be mounted given its large bore, the engine block must be drilled up.
The cylinder should be run with at least 21mm carburetor and with exhaust systems such as Stage6 R1400 or something from the Yasuni C series.
Bore = 50mm
Stroke = 45mm
Crank rod = 80mm
Piston bolt = 12mm
