Very high-end Vilebrequin Mazzuchelli (like the MHR BIG Bore), embossing ITALKIT special race 44,90mm and wire 90mm. This model is unique and perfectly designed. Full masses, it is dynamically balanced and cut into the best steels on the market, planned to be assembled without balancer. Its dynamic balancing results from the inorganic compound with tungsten carbide. The bearings, bristles of bearings are increased to Ø20mm, one does not better for a low mecaboite motor!
Tungsten carbide in summary is a combination of carbon and tungsten. It is a known very dense, very resistant and very hard material. A new rod is also installed on this embossing, ultra-strengthened model 90mm forged and machined in the mass. Ultra lightweight, it is really reserved for competition! This embalming will withstand without any problems the engine speeds of 16,000 rpm.
It's this kind of rod that equips the real competition crankshafts BIDALOT or MALOSSI MHR BIG BORE and other rarissimes vilo! Feather weight and maximum stiffness are at the appointment.
