Honda CT series
The Honda CT series was a group of Honda trail bike motorcycles made since 1964 and still produced as of 2026. The CT designation is a slight exception in Honda nomenclature in that "CT" does not indicate a series of mechanically related bikes, but rather a group of different bikes that are all for casual off-road use, as well as being licensable in most models for street use.
A description of the CT-series is necessarily convoluted because it spans several decades during which Honda altered its naming system, re-used previously issued CT designations, assigned different model names for different markets, and sometimes used multiple names for the same model within single markets. The most commonly used nomenclature is the name "Trail" being followed by the engine displacement class; thus, several different models bore the "Trail 90" designation, over a 20-year period (making this, collectively, the most popular series). Not surprisingly, the assumption is often made that any of the full-sized CT series is a "Trail 90" when first observed.
The CT designation has been used for the Trail Cub series of bikes since 1964. Alongside, a ST-series bike was renamed CT70 for the Canadian and US market from 1969 to 1994 (to further confuse the issue, both the CT70 and Z50 series were dubbed "Mini Trail," again followed by the displacement class). Honda also uses the CT designation to cover an Australia-only series of "farm bikes" for agricultural work. In 1981 Honda released a CT250S Silk Road "trekking bike", and in 1983 a Japan-only CT50 Motra minibike. These last two vehicles are mechanically unrelated to other CT-series bikes, and each other.
The Trail Cub series is an offshoot of the popular Super Cub line, and the bikes are known by several names. In Japan they were introduced as the Hunter Cub, while in the Canada/US market they were called the Trail Cub or just "Trail" followed by a number indicating engine size, such as "Trail 90". Individual models may also be known by model number, such as CT90 and CT110. In Australia the CT110 has acquired the popular moniker "Postie Bike" due to its long association with the Australia Post.
These small 17" wheel bikes are intended for relatively slow off-road travel. They have 4-stroke engines ranging from 49 cc to 105 cc, and automatic clutches. All bikes have either 3- or 4-speed transmissions, plus a second choice of HIGH or LOW bands to apply the same gears to road travel or slower off-road travel. The early bikes achieved this by having two drive sprockets at the rear wheel, which required the rider to dismount and thread the chain onto the desired sprocket. Later bikes placed the two-stage choice within the gearbox, and required the rider to only move a lever.
The initial model numbers are Super Cub numbers with the suffix H for Hunter, or T for Trail. These bikes are technically not CT-series bikes, but C- and CA- series variants. However, Honda would give the new Trail Cub line its own CT designation by 1964, so any overview of the CT-series should include these first models for clarity.
There is no CA100H because CA100 designated an America-only export Super Cub, hence H for Hunter version would not apply.
These first bikes exhibit the chief characteristics of the Trail Cub line. The Super Cub's plastic engine cover and leg shield were removed, exposing the long single tube joining the rear pressed-steel frame with the forks. The bikes have knobby tires, and the Super Cub's large front fender was replaced with a smaller unit to better clear mud. The Trail Cub has a single saddle followed by a large chrome equipment rack, on which a second saddle can be installed. There is also a skid plate to prevent damage to the low-slung engine. As with all Cubs, the fuel tank is within the seat pedestal.
