Much loved by British 17-year olds back in the seventies (where you ride on on ‘L’ plates before you’d passed your bike test), the RD250 continued a long line of sporty quarter litre 2-stroke twins from Yamaha. Proud of their racing heritage (RD – ‘Race Developed’), the RD250 owed much to the success of bikes such as the TD2 racer but was the immediate successor to the YDS7 road bike. Despite being sold in substantial numbers in the 1970’s, the RD250 in both and watercooled (RD250LC) versions is an increasingly sought after Japanese classic bike now.
