1981Yamaha SR500. First released in 1978, the SR500 was destined to become a legend as one of the most reliable and easy to maintain motorcycles ever built. It sold more units in Germany than any other Yamaha, and in Japan the SR holds cult status. Produced for over 30 years the SR500 applied the same power plant as its Brothers', the remarkable XT500 and TT500. Its featherbed inspired frame also proved successful and what was even better was the fact you could bolt on a further 20 HP without having to rework the bottom end, which made the SR a wildly popular candidate for anyone looking for a solid cafe racer. Unfortunately new noise and emission regulations signalled the end for this big air cooled single in 1999. The SR500 subsequently transformed into the smaller, more environmentally compliant SR400
