Honda TRX250 Fourtrax 1985-1987 Service Manual

Powersports Owner HQ's own history frames this bike's real significance: "the Honda FourTrax 250, also known as the TRX250, was a popular and influential ATV produced by Honda for a relatively short period during the mid-1980s... its combination of performance, reliability, and versatility set a new standard for four-wheeled ATVs and paved the way for future generations of Honda four-wheelers." One owner reviewer's own assessment captures the appeal directly: "a pioneering sport/utility ATV that helped define the four-wheel ATV segment... its legendary reliability, excellent shaft drive, and balanced performance made it incredibly popular."

Power comes from a 249cc air-cooled SOHC single-cylinder four-stroke engine — genuinely simple, durable architecture that owner testimonials consistently praise for its "simplicity, ease of maintenance, and longevity." Power runs through a shaft final drive, a genuinely low-maintenance choice over chain drive that Honda applied consistently across its FourTrax utility lineup during this era, delivering power to either two or all four wheels depending on trim.

Powersports Owner HQ's own account confirms genuine model flexibility across this run: the TRX250 was offered in both 2WD and 4WD configurations, letting buyers choose based on budget and terrain needs — the 2WD version served as the more affordable entry point, sending power exclusively to the rear wheels, while the 4WD variant added genuine all-terrain traction capability for more demanding conditions. Dennis Kirk's own factory specification sheet for the 1987 model confirms shaft drive throughout, front tires sized 21x7-10 and rear tires at 25x12-9, with 10x5 front and 9x9 rear wheels on a matching 4/110 bolt pattern — genuinely straightforward, easy-to-source componentry that's helped keep these machines running decades after production ended. New retail pricing for the mid-1980s TRX250 landed around $2,300, positioning it as a genuinely accessible utility and recreational quad rather than a premium sport machine.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 1985-1987 TRX250 FourTrax running the way it was built to.
