Introduced at the end of the 1980, the Yamaha SR 125 had the same technical specs as the 125 XT, but with 12 HP at 8500 rpm instead of 13 HP. The Yamaha SR125 is one of the oldest 125 cruiser type motorcycles on the roads today. It first appeared in the UK way back in 1982, was withdrawn in 1986, then returned in 1991.
