Ah, scooters... I used to have a lot of mopeds from my 16th birthday (in Holland you have to be 18 to be allowed doing a driving test for a >25kW motorbike or 21 to be allowed doing a driving test for >25kW).
Only the first was street legal (<50cc, <0,5kW)
Fastest things I owned was an 80cc Aprilia RS50 Chesterfield, a 128cc Honda MT-5 and a 70cc Yamaha Aerox... first two topped out over 75mph
I must say... I'm glad to have a car and my >25kW motorbike driving license.
BTW... Ruckus suckus.
