THE FRAME

The frame is made of a high resistance chrome-molybdenum steel tube with a diameter of 35 mm and a thickness of 2 mm. Specific studies and tests determined the points which are more subject to the stresses, where special reinforcements made of sheet steel will be installed. The computerized project was developed by making use of the most modern design systems, as in the case of racing karts. The frame geometry is symmetrical to obtain an optimal weight distribution taking into account the application of hard tyres. These characteristics guarantee a high structural sturdiness and much reduced weights, in favour of a better practicality and easy driving even for those drivers who are still very beginners. The original design of the forecarriage includes a flatbed divided into three distinct parts and also wide room for the driver¹s legs who can enjoy a real comfort. On the contrary in the rear axle there are 4 supports for the axle bearings in order to guarantee a better structural resistance and functionality.
