Honda CT90 Trail Motorcycle - Street (1966-1979)

The Honda CT90 Trail, produced from 1966 to 1979, was a renowned lightweight dual-sport motorcycle celebrated for its versatility and reliability. It consistently featured an 89cc (or 89.5cc) air-cooled, single-cylinder, four-stroke, SOHC engine. Horsepower typically ranged from 6.5 hp to 8 hp, with peak torque around 8.2 Nm at 6,000 rpm. Throughout its production, the CT90 received several key updates rather than distinct trim levels. Early 1966 models used a manual dual rear sprocket system. This was replaced in late 1967/1968 by a more convenient two-range sub-transmission, effectively creating an 8-speed gearbox. In 1969, the front suspension was upgraded to telescopic forks, improving handling. Later updates included foldable handlebars (1970), a standard auxiliary fuel tank (1972) for extended range, and the addition of turn signals (1974) for enhanced safety. The "K" designations primarily indicated model year updates. FAQ:
