A motorcycle transmission (4) comprising a swingarm (8) which extends from one hinging end (12) to a motorcycle chassis, defining an oscillation axis (X-X), at one connection end (16) to a wheel (20), a homokinetic joint (36) arranged on the side of the hinging end (12), and a a geared coupling (40) positioned on the side of the connection end (16), wherein the homokinetic joint (36) kinematically reciprocally connects a first end (44) of an input shaft (48), connected to a power take-off, and a second end (52) of an output shaft (56) mechanically connected to the geared coupling (40), and wherein the geared coupling (40) transmits the motion to the wheel (20). The homokinetic joint (36) performs an instantaneously constant transmission ratio between the first and the second end (44, 52), the homokinetic joint (36) is offset to the hinging end (12) of the swingarm (8), in a vertical direction (Y-Y) perpendicular to the support surface (P) of the wheel (20) and permits an oscillation of the output shaft (56) between a stroke start and a stroke end, parallel to the oscillation axis (X-X).
