Kit 80cc Ø50mm AIRSAL XTREM RED aluminum scooter PIAGGIO liquid (NRG, RUNNER ...)

Large diameter 50mm AIRSAL RED XTREM kit for PIAGGIO / GILERA liquid cooled engines. Aluminum kit, large diagrams and transfers, large diameter 50mm to offer almost 80cc of displacement (requires machining to pass it into the housings). Single segment piston, mono-block cylinder head giving a very good compression ratio ... A real racing piece with a huge bar exhaust and 7 intake transfers! To pose with a crankshaft very reinforced in race and standard connecting rod (MALOSSI MHR for example).

As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
