you cant insure a 125 for road use at 16. no arguments the MOT is purely a road worthiness test, they dont care if its got a hayabusa engine in. i would advise against this but its up to you.
with a 70 kit and a few bits and bobs you could keep up with a 125 anyway!! with a real good 70 kit and a lot of bits and bobs you could beat one
