motorcycle(s), cost handling

hey. so I’m just thinking about whether to start with a motorcycle license. am 18 years old, but I don’t have enough money. have about 2000€, but that’s for a ticket and a motorcycle. a little bit, well, but that aside. how much would it cost me to entertain a motorcycle every year, so control, insurance and everything. until I’m 21, I must have throttled it to 34 ps, no? if I do the ticket now but only at 21, then I still have this deadline for 2/3 years or so?
