1986 Honda TRX 250 Specificationsby Rob Callahan
The TRX 250 Fourtrax was an off-road four wheeled ATV produced by Honda from 1986 to 1989. It was designed to appeal to both entry-level ATV enthusiasts as well as more seasoned hobbyists, and it showcased some of Honda’s most advanced technology in ATV design at the time. Although it sold well, it was eventually replaced by the Fourtrax 350 model.
Engine and Fuel Delivery
The TRX 250 was powered by a 246 cc two-stroke engine with a Keihin 34 mm PJ oval-slide carburetor. It had a CDI ignition and a forward kick start mechanism. The engine had a compression ratio of 7.5 to 1.
Body and Transmission
The TRX 250 had a six-speed manual transmission. The vehicle had 4.3 inches of ground clearance and weighed 328 lbs. Its squat design gave it a body length of 71.9 inches and a width of 44.5 inches, and its wheelbase was 51 inches. This short, wide makeup allowed it to hug the ground during turns or under slippery conditions.
Tires, Brakes and Suspension
The front suspension consisted of double A-arms with Pro-Link progressive rate linkage. The suspension also featured a remote damper reservoir and 12-way compression and 21-way rebound adjustments. Dual hydraulic disk brakes with twin-piston calipers were on the front wheels. The rear brake was a single hydraulic disks with a twin-piston caliper. The front wheels had 10-inch tires and the rear had 9-inch tires, with aluminum rims on the front and rear.
