A fairly powerful kit in mono-segment, to accompany the AIRSAL cylinder head!
Ideal for repairing your high AIRSAL SPORT engine at a lower cost, here is the cylinder - piston kit without the cylinder head for a 50cc 2-stroke motorcycle engine with DERBI EURO 3 and 4 gearbox which equips the X-TREM, X-RACE, DRD, GPR, APRILIA after 2007 and many other machines. You can only accompany this kit with the AIRSAL 40mm cylinder head! 
Just like the cylinder / piston delivered with the cylinder head, this model has a nicasil treatment, a bar exhaust, 5 intake transfers, a fine 1mm single-segment piston with side grease nipples. It is also delivered with its clips in G, its joints ... As in the photo. 
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!
