Airsal Xtrem Tech 78.5ccm cylinder kit

The Airsal Xtrem kit is designed to meet the cubic capacity restrictions of various racing cups abroad by making the kit fit the standard stroke of 40mm. This means you have a wide range of cranks to choose from, while at the same time getting a kit with plenty of power and performance. However, the 50mm bore means you have to mill the crankcase to make room for the kit and piston.

It is recommended that you use at least a 21mm carburetor with the cylinder kit. All necessary gaskets, cylinder head, piston and piston ring, locking rings, exhaust bolts, etc. are included as shown in the picture, as well as assembly instructions.
