High Quality Content by WIKIPEDIA articles! The Honda TRX250R was a sport ATV manufactured by Honda between 1986 and 1989. It combined a lightweight frame and good handling, with a liquid cooled two-stroke engine and six speed close ratio transmission. Although only manufactured four years, the "250R", as it was known, was long a primary choice for ATV racers until the resurgence of factory involvement and usage of four-stroke engines in sport ATV`s beginning in 2003.
