High engine not approved for public roads, only reserved for competition on circuit, closed road.
Here is the high complete engine diameter Ø47.6 mm 70cc in normal stroke 40 mm (as the origin) of the great brand ITALKIT for mécaboite driving DERBI euro 3 and 4. The brand as usual, proves us by these parts of quality, its desire to offer exceptional equipment for all pilots and enthusiasts.
This Ø47.6 mm aluminum cylinder has a specific heat treatment with internal coating composed of niquel & silica. It offers an actual displacement of 71.14cc. A high-end compound guaranteeing increased strength and reliability. Equipped with 6 intake transfers and an ovalized exhaust port with optimized and very well designed boosters, the whole unit therefore has a very successful architecture and finish allowing maximum performance. A set of 4 reinforced studs is supplied, length 120 mm X Ø 7 mm.
In addition, this cylinder is accompanied by a single segment piston with graphite treatment from VERTEX. In other words, very high quality material whose reputation / quality is well established. This piston is therefore equipped with a thin chrome segment 1mm 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, a stud bolt is delivered with the cylinder. It is also of excellent manufacture and nicely laser engraved with the brand name on the cover. Aluminum alloy model for better heat dissipation, better cooling and therefore more performance. The combustion chamber mounted on O-ring with a polished finish is also improved and optimized with a revised compression ratio on the rise. A set very well suited to accompany the cylinder.
Of course delivered complete as presented, you will be very surprised by this kit which guarantees extreme reliability, performance (provided a perfect assembly), a perfect quality / price ratio.
We advise you to accompany this high engine with at least : a carburation of 21 see 24 in flexible assembly, an intake kit, crankshaft and reinforced bearing, internal rotor ignition without lights, cold racing spark plug, racing engine oil, exhaust of relaxation racing ....

As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
