The '''Honda ST-series''' minibikes are known as the '''Dax''' in Japan and Europe, and the '''Trail 70''' in Canada and the US.

The ST70 was exported to Canada and the US as the CT70. This is an exception to Honda's usual practice of prefix letters indicating the bike family, followed by engine size. The CT70 is mechanically unrelated to other CT-series bikes such as the CT50 Motra, and the CT50, CT90 & CT110 Trail Cubs. The ST90 was sold in the US as the '''Trailsport''', and was not given a CT designation.

The ST50, ST70, and CT70 were introduced in August 1969 and produced through 1981. The larger ST90 was produced from 1973 through 1975. The ST50 was reissued in 1995, and produced through 2000.<ref>{{cite web|url=http://www.honda.co.jp/pressroom/library/motor/sports/reisure/t_index.html|title=Production 1|publisher=Honda|access-date=2008-02-26}}</ref><ref>{{cite web|url=http://www.honda.co.jp/pressroom/library/motor/sports/reisure/t_index2.html|title=Production 2|publisher=Honda|access-date=2008-02-26}}</ref>

The CT70 was also sold in the US from 1981 through 1994 with a new serial number format: JH2Dxxxxxxxxxxxxx, rather than the CT70-xxxxxxx format used since 1969. These 'JH2D' bikes are not listed in Honda Japan's production figures above and are perhaps licensed production.<ref>{{cite web|url=http://www.ct70honda.com/CT70ModelIdentificationGuide.html|title=CT70 Model List|publisher=www.ct70honda.com|access-date=2008-02-26}}</ref>

A key feature of the ST-series is the pressed-steel "T-bone" frame that distinguishes it from Honda's other minibikes: the Z50 Monkey & Gorilla, the Ape, the CF50 & CF70, and the CY50 & CY80 Nautydax.<ref>{{cite web|url=http://www.honda.co.jp/pressroom/library/motor/sports/reisure/t_index.html|title=Model Guide 1|publisher=Honda|access-date=2008-02-26}}</ref><ref>{{cite web|url=http://www.honda.co.jp/pressroom/library/motor/sports/reisure/t_index2.html|title=Model Guide 2|publisher=Honda|access-date=2008-02-26}}</ref><ref>{{cite web|url=http://www.honda.co.jp/pressroom/library/motor/scooter/syaly/t_index.html|title=Model Guide 3|publisher=Honda|access-date=2008-02-26}}</ref>

As a general description, the ST-series bikes have a bench-style saddle, small fat tires, and folding handle bars. They have an air-cooled 4-stroke engine with either a 3-speed semi-automatic transmission, with an automatic centrifugal clutch, or a 4-speed manual gearbox. The ST90 uses larger 3.00-14 tires, compared to the 3.50-10 and 4.00-10 of the smaller bikes. For more detail about individual models, see the accompanying Infoboxes and the External Links section below.<ref>{{cite web|url=http://www.honda.co.jp/news/1969/2690814.html|title=General Description 1969|publisher=Honda|access-date=2008-02-26}}</ref><ref>{{cite web|url=http://www.honda.co.jp/news/1995/2950118.html|title=General Description 1995|publisher=Honda|access-date=2008-02-26}}</ref><ref>{{cite web|url=http://www.honda.co.jp/news/1972/2721107.html|title=ST 90 Tire Size|publisher=Honda|access-date=2008-02-26}}</ref>

Due to the diminutive wheel-size and limited speed, the ST-series bikes do not always qualify as road-legal vehicles and were sold in some markets for off-road recreation only. Their licensing status varies with locale and time period during their nearly 40 years of existence.

Honda's patents for the original ST-series expired in 1998, and replica bikes have become a popular export product for many Chinese manufacturers such as Jincheng, Lifan, Panda, and Redcat.

The Dax name resurfaced at the 2001 Tokyo Motor Show with the e-DAX concept vehicle, a 25&nbsp;kg folding electric wheel motor scooter meant to accompany the Bulldog concept car as a trunk bike. This car-scooter combination was previously introduced by Honda in 1981 with the City car and Motocompo folding scooter.<ref>{{cite web|url=http://world.honda.com/Tokyo2001/motor/lineup/e-dax.html|title=e-DAX 1|publisher=Honda|access-date=2008-02-28|url-status=dead|archive-url=https://web.archive.org/web/20071228090332/http://world.honda.com/Tokyo2001/motor/lineup/e-dax.html|archive-date=2007-12-28}}</ref><ref>{{cite web|url=http://world.honda.com/factbook/motor/motorshow/200110/06.html|title=e-DAX 2|publisher=Honda|access-date=2008-02-28}}</ref>
