MOTORCYCLE HAVING A SYSTEM FOR INCREASING A REARING AND A TILTING LIMIT OF THE VEHICLE AND FOR INCREASING A LONGITUDINAL THRUST OF THE VEHICLE

摘要

Motorcycle (1) comprising a frame (2) to which an internal combustion engine (3) is associated, from which internal combustion engine at least one exhaust pipe (6) of combusted gases departs, the exhaust pipe having an open terminal portion, said frame (2) being mounted on a front wheel (4) and a rear wheel (5), a control board or control unit (10) being included, for controlling the torque produced by the engine (3) and other parameters such as the velocity of the vehicle and the spatial position thereof with respect to the road surface, the motorcycle (1) comprising a system able to verify when the front wheel (4) of the motorcycle detaches from the road surface during an acceleration. The system comprises choke means (36) for partialising the section of the exhaust gases outlet area from said exhaust pipe (6), during said partialisation, the partialisation being obtained as a function of the torque produced by the engine (3) and of the position of said front wheel (4) with respect to said road surface.
