hi everyone i am at the moment 15 years of age and me and my farther are both into motorbikes and i have been riding bikes since the ages of 12. my dad owns an yamaha r1 2004 triumph tt600 and a honda dominator 1994. i myself own a peugeot speedfight 2 50cc and a malaguti xsm50 supermoto but at the age of 17 my dad is giving me his dominator but i would need to restrict it from 44bhp to 33bhp.....how much would this cost in total???
