Here is the 75cc AIRSAL high engine kit for DERBI euro 1 & 2 engines. Very well known to date in the industry, this kit is one of the best value for money on the market! This Ø48mm diameter model has very good performance. Indeed, it is equipped with a mono-segment piston to allow high revs (reduction of friction), 5 significantly improved transfers and a large bar exhaust which make this kit a big performance asset.
Its finish is excellent, it is obviously made of 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 small or large configuration, it will be perfect for riding every day ... We must not neglect and forget that we are far from the quality and performance of a BIDALOT, MHR kit, ...
Its cylinder head is a model with high compression entering chamber, polished finish. A small alignment may be welcome (cylinder / casings) but it is in no way mandatory for the proper functioning of this high engine. You will understand, this kit with its attractive price will offer you good performance!
We recommend this kit with at least : reinforced crankshaft and bearings, minimum 21mm carburetor, racing exhaust, cold racing spark plug, reinforced clutch ...

X1 segments Ø48mmX1mm fine chrome
X1 single-segment piston
X1 complete seal pack

Optionally we offer a stage 1 preparation, this preparation is a modification of the exhaust light by increasing the diagrams and improving the duct, it increases the performance of the cylinder.
