The Arcobaleno Formula was designed with the precise purpose to put a powerful, safe and reliable race car on the market. It is the ideal car for the racing enthusiasts looking for fun, excitement and, above all, for the young people coming from karting willing to approach the racing world.

The Arcobaleno offers high performance and maximum safety, with very simple and extremely reliable mechanics. In order to get reliability, to optimize the power/weight ratio and to keep the maintenance costs low, it is powered by a standard motorcycle engine with a power output of 140 HP. The total weight of the car Is 816 lb. (370 kg). Particular care was taken in the frame design. Its strength capability was designed to exceed the expected engine power. Rigid frame, simple and efficient technical solutions, adjustable suspensions, possible aerodynamic adjustments coupled with the specific tires which quickly dissipate the kinetic energy in case of spinning: AII these features make the Arcobaleno Formula a very professional single-seat car, which involves the driver to constantly search for his own limits without omitting the pleasure of a fast and exciting track experience.
