The Corsario has a steel, double cradle frame with the engine suspended to facilitate the assembly and disassembly of it. The engine is secured to the chassis by its front part by two screwed on aluminium plates.
Increasing the rigidity has been sought after and this has been performed by means of a pyramid structure which takes the shock-absorber and a reinforcement of four crossed tubes which reach the steering head. At the union area with the axle of the rear swinging arm, small plates have been welded for the same purpose.
The rear swinging arm, also made from steel is fairly long (taking into account the 1400mm distance between the axles) thanks to the fact that the engine can be mounted well forward due to the fact that it does not require a radiator.
