2027 Triumph Street Triple 798 Gets New Engine and Chassis

Triumph Reveals Major Updates for 2027 Motorcycles

Triumph has revealed initial details of its 2027 motorcycle lineup, led by the 2027 Triumph Street Triple 798 alongside updated Tiger 900 and Tiger 1200 models and the Bonneville T40. The company plans to release complete information for the three motorcycles in stages over the coming months. The Street Triple receives the most substantial changes, centered on a new 798cc three-cylinder engine, revised chassis and updated styling. The Tiger 900 and Tiger 1200 will instead focus on performance and technology enhancements. Triumph has not yet disclosed complete specifications for the updated motorcycles, leaving additional technical and equipment details for their scheduled individual reveals.

Street Triple 798 Gets New 798cc Engine

The most significant mechanical change for the Street Triple is the adoption of a new 798cc inline three-cylinder engine. Triumph developed the engine alongside its involvement in the Moto2 championship, linking the production motorcycle's new powerplant to technology development from its racing program. The Moto2 engine uses a new cylinder head, redesigned valvetrain, revised combustion chamber and higher-flow ports. Triumph has previously stated that its Moto2 unit delivers a 6 percent increase in peak power while reducing weight by 2kg. The production engine is expected to use a similar architecture, but Triumph has not yet released its complete specifications.

Revised Frame and Styling Transform Street Triple

The 2027 Street Triple also receives substantial chassis and design revisions beyond its new engine. The motorcycle adopts a new frame and a more substantial double-sided swingarm, while its exhaust system moves to an underbelly configuration. Styling changes are also prominent, with the familiar bug-eye headlamps replaced by perimeter LED units incorporating a central main beam. These changes give the motorcycle a revised visual identity while accompanying the underlying chassis updates. Despite the extent of the revisions, Triumph has not yet announced the complete technical specifications or performance figures for the new Street Triple 798, so its final output and dynamic characteristics remain undisclosed.

Tiger 900 and Tiger 1200 Add Radar Technology

The Tiger 900 and Tiger 1200 will receive performance increases and technology updates for the 2027 model year. Studio images show front-mounted radar systems on both adventure motorcycles, indicating that Triumph may be preparing rider-assistance functions associated with radar sensing. Possible applications include adaptive cruise control and potentially blind-spot detection, although the company has not confirmed the exact functionality of the systems. The Tiger 1200 was also previously spotted during Sam Sunderland's round-the-world record attempt. Both motorcycles receive updated bodywork while maintaining the familiar Tiger design and overall silhouette, preserving the established visual identity of the adventure-bike range.

2027 Triumph Reveal Schedule

Triumph will disclose the three motorcycles through a staged reveal schedule extending from October through December 2026. The Tiger 1200 is scheduled for its reveal on October 27, followed by the Street Triple 798 on November 17 and the Tiger 900 on December 15. Each event is expected to provide the full specifications, performance figures, equipment details and other information that have not yet been disclosed. The staged approach means technical information about the updated motorcycles will become available progressively rather than being released as one complete lineup announcement.

Industry Impact & Outlook

Triumph's 2027 updates show a two-track development strategy for its motorcycle portfolio, combining a substantial powertrain and chassis redesign for the Street Triple with technology-focused upgrades for its adventure models. The introduction of radar hardware on the Tiger 900 and Tiger 1200 could expand the use of rider-assistance technology in Triumph's motorcycles if the company confirms functions such as adaptive cruise control or blind-spot detection. Meanwhile, the new 798cc engine gives the Street Triple a revised technical foundation influenced by Triumph's Moto2 development. The upcoming staged reveals will clarify how these changes translate into final performance, equipment and production specifications.
