As Dan says i wouldn't worry! Even if it was made law how could they know what hp ur bikes puttin out? look at the amount of sd riders (me included) who have fitted pipes, pc111's remaps etc, no-one would be able to stop people derestricting them. My son bought a brand new scooter and the first thing we done was change everything on it so it will do 50mph now, when he first went out on it i followed him just to make sure he was ok and at 30mph it's fookin dangerous
