A gear change mechanism for motorbikes and motorcycles with two or more gears that can be inserted by the driver, because the small gear contains a freewheel coupling, while the large gear or the larger gears can be interspersed with choice through a clutch coupling and disengageable at will, for example a dilatable coupling which in a known manner saves the freewheel coupling.
