Here is a kit known by all those in the field! Both taken as an example for the preparers and used by the less connoisseurs who drive every day… This AIRSAL is certainly the best quality / price ratio on the market! This luxury model has a two-segment VERTEX piston modified by AIRSAL. It is more torquey and solid than the single-segment model that we also offer at a lower price.
It is taken as a basis by many preparers because its channels, its distribution, its bar exhaust are really big assets! Its finish is excellent, its diagrams have a good torque / power ratio. In relation to the AIRSAL for DERBI euro ½, this AIRSAL for DERBI euro 3 and 4 has large intake diagrams and a special form of transfers, you will need to align the crankcases at best to this cylinder.
You can accompany it with a small or large configuration, you can use it for stunt, race, ride every day…. Clearly this kit is really suitable for any type of activity. It is clear that we are far from the quality and performance of BIDALOT, MHR, BIDALOT… the cylinder head is a high compression inlet chamber model with a polished finish. A small alignment could be welcome (cylinder / crankcases) but it is in no way obligatory for the proper functioning of this high engine.
We recommend this kit with at least : reinforced crankshaft and bearings, minimum 21mm carburetion, racing exhaust, cold racing spark plug, reinforced clutch ...
The pack contains :
X2 segments d.50mmX1mm including a domed chrome for the top of the piston
X1 VERTEX / AIRSAL bi-segment piston
X1 complete seal pack
X1 piston pin
X2 piston clips
X1 high compression cylinder head incoming stud
X1 notice
X1 exhaust / cylinder head bolts kit
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!
