Good in theory but unless your under 24 you will still be restricted to 33 hp for 2 years, basically a heavily restricted 600cc. Better off sticking with a decent 125 under those conditions.
Used to be 21, my son when reaching 21 enquired about taking a direct access course but told the rules...
Cheap Chinese scooters. Will give you 3-4 years motoring at best. If that's reflecting in what they cost.
Then a good buy, but they will show signs of rust from a very early age.
