Vehicle Information
Honda CT125 Trail Motorcycle - Street (1977)
The 1977 Honda CT125 Trail was a unique, single-year import to the U.S., designed as a versatile utilitarian and adventure motorcycle. It featured a robust 124.0 ccm single-cylinder, four-stroke engine, producing 9 horsepower at 8000 rpm. This air-cooled engine had a bore of 56.5 mm and a stroke of 49.5 mm, with an 8.0:1 compression ratio, fed by a Keihin carburetor. The CT125 Trail was offered exclusively in a Shiny Orange color with distinct "TRAIL 125" decals, equipped with a solo seat, chrome rear carrier, and brush guards. While the 1977 U.S. model itself saw no mid-cycle changes, its underlying platform received significant updates in 1976, prior to its American release. The original 122cc engine was upgraded to 124cc with a two-piece head, and the frame geometry was revised to enhance rideability. These pre-release modifications ensured the 1977 CT125 Trail was a refined and capable machine for its target market. FAQ:
