The gearbox is an important component of a Moto Guzzi engine, which enables power to be transmitted from the crankshaft to the rear wheel. A complete gearbox includes all the necessary components such as gears, bearings, shafts and seals to assemble and operate the gearbox. It may be necessary to replace the complete gearbox if the existing gearbox no longer functions or can be repaired due to wear or damage.
