Only for competition, cylinder displacement exceeding the limit.
Here kit 80cc up first prize in the Spanish house AIRSAL engine, this model we call Sport, also available in Luxury with two-piston segment of the TECH 149.89 euros from us! This kit has certainly a cheap yet a good quality and present performance.
Its diameter of 50mm still offers real 78,53cc combination of normal race 40mm DERBI so. Its architecture is excellent, its channels 5 numbers are very well finished and has a large exhaust with bar. It will offer high speeds, torque and longevity!
Indeed, the diagrams have a good ratio torque / high rpm, coupled to this large diameter 50mm we recommend this cylinder with a good configuration anyway! A good racing exhaust, a 24mm minimum carburetion to operate well, a crankshaft and reinforced bearings ...
The finish is really good for such a price. The piston is bi-model segments for hard chrome domed, it has side oilers. The cylinder head is a high-compression chamber is incoming to have good alignment chamber / cylinder and a good performance head gaskets. The room is a polished hemispheric model. This cylinder head allows you to reconnect if desired antifreeze on your carburetor.
Clearly this cylinder is really a superb quality / price / performance ratio! It will certainly be less effective than MALOSSI MHR, BIDALOT, or POLINI because its distribution, its canals, the study, the venturi exhaust ... are relatively limited, it is a al'identique nykasil scanimet, has the incomparable nykasil hard ceramic or plasma! But there will already very efficient, especially for those who do not want a kit complex and difficult to talk. A good trainer will also draw quite astounding performance.
