I have bought a CRF230 2004 for my 14 year old daughter, The bike was geared down but I have change the sprockets back to (Rear 50 teeth) (Front 13teeth). I rode it the other day and got my mate to clock me in at 110kph. I weigh 90kg so with a lighter person on it it may do between 110kph - 120kph. hope this helps regards Alistair
