Specifications for the Honda ATC125

• Honda introduced the all-terrain vehicle to the world in 1970 in the form of a three-wheel motorcycle-based vehicle that could traverse many different off-road obstacles. The ATC125 was one of the last Honda three-wheelers because all manufacturers in the USA were required to stop selling them due to a high accident rate. This paved the way for four-wheel ATV development at Honda, which are still being manufactured as of 2010.

Standard Equipment

• The Honda ATC125 had an electric starter as standard equipment. The standard four-speed transmission had a dual-range capability and an automatic clutch. Low range provided more pulling power, while high range allowed a higher top speed. To change gears, you merely released the throttle first because there was no clutch lever. The ignition system was electronic, making a conventional tune-up unnecessary. The chain final drive had an automatic adjuster as standard. Brakes were included on front and rear wheels. A 12-volt electrical system was standard. The plastic fenders had built-in mud guards.

Engine and Mechanical

• The 124cc, single-cylinder four-stroke engine had an overhead cam. The cylinder bore was 55 mm, while the crankshaft stroke was 52.2 mm. A 20-mm piston-valve carburetor delivered fuel. Final drive was by a sealed "O" ring chain. Cable-controlled levers on the handlebars and a foot pedal on the right-hand side activated the front and rear drum brakes. A shift lever near the left-hand foot pedal operated the four-speed transmission.

Exterior Dimensions

• The overall length of the ATC125 was 65.9 inches, width was 38.6 inches and height was 37.4 inches. The ground clearance was 4.5 inches. The wheelbase was 42.3 inches. Seat height was 25.4 inches from the ground. The dry weight, or the weight without tool kit, gas or oil was 277.8 pounds. The fuel tank could hold 2 gallons, including a 2/10-gallon reserve.

Optional Equipment

• An optional cooler rack could be mounted to the rear of the ATV to haul a food and drink cooler. A water-resistant fabric cover was available as an option to keep the elements from damaging the ATV. Because tire pressure was critical for correct performance, a tire pressure gauge was also available.
