The Honda CT-90 was a small step through motorcycle manufactured by Honda from 1966 to 1979. It was offered in two models - "Trail" or "X" with the main variations being gear ratios and tyre style. Perhaps one of Honda's hidden success stories, this bike sold well worldwide and has a faithful following to this day and has become collectible.

Basic Information
The CT90 in its classic form was an 89cc 4-stroke air-cooled single with a four-speed transmission and an automatic clutch, coupled with a 1.867:1 ratio reduction box switched into operation using a small lever under the transmission case. The cylinder was nearly horizontal in the step-through tube/stamping frame. The fork was originally a leading link suspension, replaced in 1969 with conventional telescoping-tube suspension.

The CT90 ended production in 1979, replaced the following year by the Honda CT110, which was essentially the same machine bored out to 105cc and weighing slightly more. The 1980 CT110 lacked the sub-transmission, however it returned in following years.

Honda targeted hunters, fishermen, commuters and outdoorsmen with the Trail 90. Early ads often featured these bikes in wilderness settings, and they were very well suited for narrow trails, being small, lightweight (around 188 pounds) and with a forgiving suspension. It was ideal for climbing and carrying packs. The four-stroke engine was quiet and almost all models were equipped with spark-arrestor exhausts.

While targeted at off-road uses, this was not a "dirt bike" in the conventional sense. What's more, they could and often were registered for road use and had a top speed in hi-ratio road gear of around 55mph or 80kmh. Fuel economy was excellent, often around and above 100mpg. In local commuter traffic, they were extremely maneuverable, though they were poorly-suited for highway travel due to limited power, off-road-biased tires, and top speed.
