In stock form the motor is held back by the baffle and air box lid, but when you spend $40.00 on the cherry bomb remove the air box lid and baffle the bike wakes up big time. I rode mine at the track totaly stock last weekend and thought the same thing, this weekend I rode it with the cherry bomb and what a difference, the bike pulled very hard and was just as fast if not faster than my friends 450r with pipe, filter, and cam.
As for the suspension with a little tuning it can be soften up quite a bit. It does come very stiff from factory.
RIDE IT LIKE YOU STOLE IT!!!!
