hopefully. i am just thankful that two stroke streetbikes are both legal and plentiful here in japan. also, bikes below 250cc are exempt from inspection, so swapping a 500cc motor into a 250cc frame is illegal, but undetectable because the chassis number. if you have ever wondered why two strokes are "249cc" and "124cc" its not borexstroke voodoo, its japanese inspection requirements being met. an actual 250c bike would be bumped into the "under 400cc" category. same with the cars, there is a reason all the 4 cylinders are 1998cc (and called 2.0 liters)
but thats the plan, i always wanted what almost equated to a 500cc "motogp" bike.
