Harley-Davidson could significantly expand its performance-focused ST motorcycle lineup in 2027. The expected additions include the Road King ST, Road Glide ST and Street Glide ST, which may feature the Milwaukee-Eight 117 engine along with upgraded suspension and braking components.
The American motorcycle manufacturer currently lists two ST models on its US website: the Low Rider ST and the Pan America 1250 ST. The possible arrival of three new touring motorcycles would broaden the range and bring more performance-oriented options to Harley-Davidson’s Grand American Touring category.
Although the Road Glide and Street Glide are already available in premium CVO versions, their proposed non-CVO ST variants could offer buyers alternatives without some of the more exclusive equipment found on the top-end models.
Harley-Davidson Road King ST: What We Know So Far
Speculation about the upcoming Road King ST gained momentum after an accessories page for the motorcycle briefly appeared on Harley-Davidson’s website before being removed. Similar listings for the Road Glide ST and Street Glide ST have also reportedly surfaced, suggesting that the company may be preparing these models for a possible 2027 introduction.
The Road King has appeared in different configurations over the years. In 2025, it was offered in Special form with the Milwaukee-Eight 114 engine, side cases and no windshield. The standard Road King was last available in 2022, when it featured the Milwaukee-Eight 107 engine, side cases and a windshield.
Harley-Davidson has not yet disclosed the design or technical specifications of the proposed Road King ST. The brief appearance of its accessories listing, however, has added to expectations that a new version could be in development.
Expected Engine, Suspension and Braking Upgrades
Harley-Davidson uses the ST badge for motorcycles designed with a stronger focus on performance. These versions generally receive more powerful engines or upgraded suspension components compared with their standard counterparts.
The Road King ST, Road Glide ST and Street Glide ST are expected to follow the same approach. All three could use the Milwaukee-Eight 117 engine, which is already available in several Harley-Davidson touring motorcycles. Sportier suspension and upgraded braking components are also anticipated, although the company has not confirmed these details.
The existing CVO versions of the Road Glide and Street Glide use the larger Milwaukee-Eight 121 engine. If the non-CVO ST models receive the 117 engine, their output would be lower than that of their CVO counterparts.
The proposed ST variants may also feature less premium equipment than the CVO models, potentially including the omission of certain carbon-fibre components.
How CVO Models Differ From Standard ST Motorcycles
CVO stands for Custom Vehicle Operations, Harley-Davidson’s premium customisation programme. These motorcycles are known for limited production runs, exclusive paint finishes, distinctive colour combinations and upgraded components.
Launched in 1999, the CVO programme has also allowed Harley-Davidson to explore new styling treatments and accessories that could eventually influence other models in its range.
The anticipated non-CVO ST motorcycles would sit below the corresponding CVO versions, potentially offering a performance-oriented touring experience without all the premium features associated with the more exclusive models.
Deadwood and Super Glide Could Also Be in Development
The three expected ST motorcycles may not be the only additions under consideration for Harley-Davidson’s future lineup. Accessories pages for the Deadwood and Super Glide have also reportedly appeared online, raising the possibility that the manufacturer is preparing additional models.
However, Harley-Davidson has not officially confirmed the Road King ST, Road Glide ST, Street Glide ST, Deadwood or Super Glide for 2027. Their final specifications, colour options and launch dates remain unknown.
