Vehicle Information
Honda FourTrax 250R ATV (1986-1989)
The Honda FourTrax 250R, produced from 1986 to 1989, was a high-performance sport ATV renowned for its liquid-cooled, two-stroke engine and six-speed transmission. It quickly established itself as a benchmark in its category, offering a combination of power and handling. While the FourTrax 250R was offered as a single model without distinct trim levels, Honda introduced significant yearly updates. The most notable change occurred in 1988, with the introduction of an all-new frame and a shorter aluminum swingarm, significantly improving handling. Engine refinements also took place, such as a longer connecting rod in 1987 and an increased compression ratio in 1988, as well as a needle bearing in the clutch pressure plate in 1989. These evolutions allowed the 250R to remain competitive throughout its production run. FAQ:
