just to clear things up, the xt 550 yamaha 1982 and 1983 actually has 55 hp at 5300 rmp stock standard and are very compeditive infact faster on the quarter mile than the new xtz660 with standard gear ratios, i know this because im sponcered by yamaha and have been doing xt550´s up for 3 years and know them inside out. and with a top speed of 190 clicks k´s that is they are a great touring bike for all experienced riders no matter their height
