The TT250 (and its XT 250 brother) have several hidden secrets. They are light at about 107.04 Kg (236 pounds) with the 2.8 Kg (6.2 pound) silencer removed (CRF 230 is 105 Kg (233 lbs). 105 kg is pretty light for a four-stroke. They have a low seat height of 83.82 cm (33 in) which makes touching the ground twixt trees easier.
