i want a upgrade from my old dirt bike. im 15 and am 5 foot 6 inches. the 250s are the same size as teh 125s and 450s after reaseraching a bit(its not exactly the same size but in the same range so lets just say same size) amd i tall enough for a 2stroke 250cc dirt bike. if its about my being able to pick up the bike i lift and do other stuff so height is the only issue. am i tall enough??
