Yes there are! one is gear box oil(transmission oil) it stays in the gear box and lubricats the gears untill its liftime is up and you are to drain and change it. The other is engine 2 T oil which is burned with the gas to lubricate the pistons.
The gear oil deppends if you are a $$ person then as regular as possible(use synthetic).
The 2T oil make sure its good stuff and top it up after every ride if possible(like Andy). Or straight away if the red light comes on. someone said earlier on if you run out of 2T your engine will blow up!
