Valcon Games tried with this and almost got there.
Difficulty : Hard
Super-bikes racing opponents are too fast and you could become last in a small amount of time (it is hard to win a race.)
A good idea this game had is to (while in career mode) have a fuel gauge which when the gas got more empty the bike would be lighter and faster but the challenging part is that the big sidecars could not be refueled.
Valcon Games tried with this and almost got there next time they should add some music and make the opponents catch able and not having you lose all of the time.
