Gearbox assembly (two shafts with gears) for Viper 125-200 cc motorcycles and similar (China, Minsk). The gearbox consists of an input shaft and an output shaft with gears that are shifted to change the gear ratio between the engine and the wheel.
Signs of wear: gears jump out of engagement, engage with a crunch or do not engage at all, and noise and whine are heard from the gearbox. It is better to replace the assembly as a set so that the gears wear evenly.
