Here is the 80cc luxury AIRSAL high engine kit for DERBI euro 1 & 2 engine.
Well known in the industry, this kit is part of the best quality / price / performance ratio on the market!
This Ø50mm diameter model has very good performance for a fair price.
Indeed, it is equipped with a two-segment piston to allow more torque and two thin segments for high speeds (reduction of friction), 5 largely improved transfers and a large bar exhaust which make this kit a concentrate of performance.
Its finish is excellent, it is obviously in high quality nikasil treated aluminum. Its diagrams are just as excellent in a good torque / high speed / power ratio. You can accompany it with a medium or large configuration, it will be perfect for everyday riding, racing, stunts ...
We must not neglect and forget that we are far from the quality and performance of a BIDALOT or MHR kit ...
Its cylinder head is a high compression inlet chamber model with a polished finish. A small alignment would be welcome (cylinder / crankcases) but it is in no way compulsory 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 fine segments Ø50mmX1mm including a chrome for the top of the piston
X1 twin piston rings
X1 complete seal pack
X1 piston pin
X2 piston clips
X1 high compression cylinder head incoming stud
X1 cylinder
X1 notice
X1 exhaust screws
As an option we offer you a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
