Changing the oil in the gearbox
Every 15,000 km, check the oil level in the gearbox, which should reach the lower edge of the filler hole.
Change the gearbox oil every 30,000 km. Do this immediately after a ride while the oil is warm.
Drain the used oil through the drain hole, to speed up the drain, unscrew the plug and the filler hole.
Replace the drain plug and fill the gearbox with fresh oil up to the level of the lower edge of the filler hole.
The drain and filler plugs of the gearbox have a tapered thread that ensures their tightness. Pay attention to their correct wrapping.
