This machine was in production for the 1985 1992 model years. During its run, it underwent three major engineering makeovers. However, the major core features were retained. These were: a sophisticated long travel suspension, a liquid cooled two stroke motor and a fully manual 5 speed transmission for 85 86 models and a 6 speed transmission for the 87 92 models. It was a machine exclusively designed for racing by highly skilled riders. Honda responded a year later with the FourTrax TRX250R a machine that has not been replicated.
