High-end crankshaft with 90mm forged connecting rod and Ø20mm bearings, for engine without balancer shaft, increased cage, 14mm increased piston pin, very high quality steel, top dynamic balancing, excellent diagrams, high compression stud cylinder head, excellent ratio compression, cooling studied with a semi-closed type cylinder, large diameter exhaust with boosters passing on the lateral transfers, 6 large intake transfers with studied shapes and specific architecture, 44.90 stroke with Ø52mm piston diameter, graphite piston , .



As usual, the brand ITALKIT do not deviate from the rule by composing this pack of the best current parts on the market. The aluminum alloy cylinder has a specific heat treatment and an internal niquel/silica coating and an external chrome coating, giving it all its solidity and reliability, foolproof! Equipped with no less than 9 lights including 6 intake transfers including 3 side and 2 at the rear, 2 boosters with elaborate shapes passing on the sides and finally the exhaust outlet, impressive in its shape and size to such an extent that the outlet diameter has been increased and measures no less than Ø30mm, between fixing axis for the exhaust 46 mm.



The competition had better watch out and is far behind on most maxi-kits. The only negative point of this pack is the absence of a set of clutch springs, celeron bearings and several base gaskets like the packs for AM6! A novelty from the big Spanish brand ITALKIT and finally available from us, this ultra complete 96cc engine pack mounts on mécaboite engine DERBI Euro 1 & 2. This set will give you all the power you need to stand out in competition and win first place.



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 obtain a significant performance gain, in fact the less an engine runs out of steam and heats up. and the more performance remains present. To accompany this cylinder, a competition stud cylinder head! Top-of-the-range model, specially designed to offer maximum compression. The cylinder head stud has a hemispherical shaped combustion chamber and has a very successful, smooth and clean polished finish. Room volume revised upwards at the same time.



The 50mm piston is not chosen at random, it is a single segment model with graphite treatment. In other words, very high quality equipment whose reputation/quality is well established. This piston is therefore equipped with a thin chrome-plated segment, 1 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 matching perfectly with this cylinder to support sharp recovery, sudden change of diets and prolonged endurance on the circuit.



Finally, the special 44.90mm stroke crankshaft and 90mm connecting rod without balancer. This model is unique and once again, really successful. It is perfectly balanced and cut from the best steel 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 known to be very dense, very resistant and very hard. A new connecting rod is also installed on this linkage, an ultra-reinforced model machined from the mass. Ultra light, it is really reserved for competition!



It is this type of connecting rod that equips real competition crankshafts BIDALOT or MALOSSI MHR BIG BORE and other extremely rare vilo! Featherweight and maximum rigidity are there. Its lubrication is improved, the connecting rod small cage is increased for better holding, silver treated and mounted on anti-friction shims. A connecting rod assembly, as you will have understood, perfectly designed and adapted to accompany this high engine, able to withstand without any problem the wildest engine speeds of up to 16,000 rpm and in combination with this cylinder and the stroke 44.90mm, the actual displacement is 95.35cc.



In short, this 96cc Ø52mm racing pack / kit for your engine DERBI euro 1 & 2 will be an essential asset to offer you assured victories and guaranteed sensations! Delivered complete as presented, you can trust the photographs, they are contractual as usual.
