Equipped with no less than 9 lights including 6 intake transfers, 2 shaped boosters and finally the impressive exhaust outlet by its shape and size to such an extent that the outlet diameter has been revised upwards and measures no less than Ø30mm, between axis of mounting for the exhaust 46 mm.
That's not all, the cooling has also been completely revised and corrected in order to offer the best possible heat exchange and at the same time to obtain a significant performance gain, indeed less an engine runs out of steam and overheats. and the more the performances remain present.To accompany this cylinder, a cylinder head with competition stud! Top-of-the-range model, specially designed to offer maximum compression. The cylinder head stud is unfortunately not entering and mounted on an O-ring, the combustion chamber is hemispherical in shape and has a very successful polished finish, smooth and clean.
The Ø47.6mm piston is not chosen at random, it is a single segment model from ITALKIT with graphite treatment. In other words, very high quality material whose reputation / quality is well established. This piston is therefore equipped with a fine chrome segment 0.80 mm thick thus promoting the increase in speed. Thanks to the graphite treatment, its shapes and its composition, this piston has been very well designed and studied in order to offer better thermal expansion, at the same time fitting perfectly with this cylinder to withstand frank revisions, sudden changes of regimes and prolonged endurance on the track.
Finally, the special 42mm stroke crankshaft and 90mm connecting rod. This model is unique and once again very successful. It is perfectly well balanced and cut from the best steels on the market. Its dynamic balancing results from the inorganic tungsten carbide compound. This material in summary is a combination of carbon and tungsten. It is a material reputed to be very dense, very resistant and very hard.A new connecting rod is also installed on this linkage, an ultra-reinforced model machined in the mass. Ultra light, it is really reserved for competition!
Featherweight and maximum rigidity are there. Its lubrication is improved, the small end cage is increased for better holding, treated with silver and mounted on anti-friction wedges. A crankshaft as you will have understood, perfectly designed and adapted to accompany this high engine, which can support without no problem with the craziest engine speeds of up to 16,000 rpm and in combination with this cylinder and the 42 stroke, the actual displacement is 74.73cc with no less than 20cv announced by the brand on condition of a perfect assembly and adjustments in the rules of the art!
