Triumph has revealed the first look at its all-new 2027 Triumph Street Triple 798, and the new generation looks set to be a much bigger transformation than a routine model-year update. The iconic middleweight streetfighter is moving away from its familiar 765cc platform and adopting a new 798cc three-cylinder engine derived from Triumph’s latest Moto2 development programme, while the chassis and styling have also undergone major changes.
The engine is only one part of the story. Triumph has introduced a new frame, a chunkier double-sided swingarm, revised rear suspension packaging and a new underbelly exhaust. At the front, the familiar Street Triple bug-eye design has also been replaced by a sharper new LED setup. However, Triumph is keeping the most important production figures under wraps for now, with the full Street Triple 798 reveal scheduled for November 17, 2026.
New 798cc Moto2-Derived Engine Is the BIG Upgrade
The biggest mechanical change is the move from the existing 765cc triple to a new 798cc inline three-cylinder engine. Triumph has developed this new-generation powerplant alongside its Moto2 programme, bringing its latest three-cylinder engineering experience into the road-bike range.
Earlier details from Triumph’s Moto2 development programme have highlighted a new cylinder head, redesigned valve train, revised combustion chamber and higher-flow ports, with the new engine architecture focused on improving performance while reducing weight. The production Street Triple 798 is expected to draw from this development, although Triumph has not yet confirmed that every Moto2-engine component will be identical on the road motorcycle.
| Specification | New Street Triple 798 | Current Street Triple | Status |
|---|---|---|---|
| Engine | 798cc Inline Triple | 765cc Inline Triple | Confirmed |
| Engine Development | Moto2-derived | Existing platform | Confirmed |
| Power | Not revealed | Variant dependent | Pending |
| Torque | Not revealed | Variant dependent | Pending |
| Kerb Weight | Not revealed | Variant dependent | Pending |
| Full Specification | November 17, 2026 | Already available | Confirmed |
This distinction is important because the Street Triple 798 should not be described as receiving the actual Moto2 race engine. It is a road-going production motorcycle using technology and development experience derived from Triumph’s Moto2 programme. The final power and torque figures are still unknown, and those numbers will be among the biggest highlights of the November reveal.

Aggressive New Design Gives the Street Triple a Fresh Identity
The larger engine comes with a dramatic visual transformation. Triumph has moved away from the Street Triple’s familiar twin bug-eye appearance, introducing a new front-end design with perimeter LED lighting and a central main beam. The result is a sharper and more aggressive face that gives the motorcycle a noticeably different personality.
The bodywork has also been redesigned around the new generation. The fuel tank and surrounding panels look more muscular, while the new 798 graphics make it immediately clear that this is not simply another version of the existing 765. Despite the changes, Triumph has retained the compact proportions and exposed mechanical character that have always been central to the Street Triple identity.
Another major change is the underbelly exhaust, which replaces the previous exhaust arrangement. The lower positioning gives the rear section a cleaner appearance and complements the redesigned chassis, making the motorcycle look more compact and performance-focused from the side.
Completely Revised Chassis Could Make It Even More Agile
Triumph has not simply installed the larger engine into the existing platform. The Street Triple 798 gets a new frame and a substantially revised double-sided swingarm, while the rear suspension arrangement has also been reworked. These changes suggest that Triumph has developed the chassis specifically around the new engine rather than treating the 798 as a simple displacement upgrade.
That could be particularly important for Street Triple enthusiasts. The outgoing motorcycle is known for its sharp handling and playful character, so increasing engine capacity without revising the chassis could have affected the balance of the bike. Triumph is instead targeting an even more agile riding experience with the new generation.
The first images appear to show Showa front suspension, Brembo braking hardware and alloy wheels, although the complete specifications of these components have not yet been confirmed. Exact suspension settings, brake dimensions, geometry and other chassis figures should therefore be treated as pending until the official November reveal.
| Chassis Area | New Street Triple 798 | What It Means |
|---|---|---|
| Main Frame | New design | Major structural revision |
| Swingarm | New, chunkier unit | Revised handling package |
| Rear Suspension | Revised layout | New chassis balance |
| Front Suspension | Showa hardware visible | Premium performance hardware |
| Brakes | Brembo hardware visible | Performance-focused setup |
| Exhaust | Underbelly layout | Cleaner rear profile |
Street Triple 798 vs 765: This Is More Than a Bigger Engine
The move from 765cc to 798cc may look relatively small on paper, but the scale of the overall redesign tells a very different story. Triumph is changing the engine generation, frame, swingarm, rear suspension arrangement, exhaust and front-end design at the same time.
The additional displacement should give Triumph more room to improve performance and torque delivery, while the revised chassis is intended to maintain the agile character associated with the Street Triple family. That combination could make the new motorcycle feel considerably different from the current 765 even if its three-cylinder character remains familiar.
For existing Street Triple owners, the biggest question will be whether Triumph can extract significantly more performance from the larger engine without losing the responsive and playful character that has made the motorcycle such a popular choice in the middleweight naked-bike segment.
| Area | Street Triple 798 | Current Street Triple 765 | Direction |
|---|---|---|---|
| Engine | 798cc Triple | 765cc Triple | More performance potential |
| Chassis | New | Existing platform | Greater agility |
| Front Design | New LED setup | Bug-eye design | More aggressive |
| Exhaust | Underbelly | Existing layout | New packaging |
| Swingarm | New design | Existing unit | Revised dynamics |
| Electronics | Not revealed | Existing package | Awaiting confirmation |

Premium Hardware Looks Serious, But the Full Package Is Still Hidden
The first Street Triple 798 images already suggest that Triumph is maintaining a premium performance focus. The visible Showa suspension and Brembo braking hardware fit the motorcycle’s positioning, while the redesigned frame and swingarm indicate that handling remains a major priority.
However, this is also where buyers need to wait for the official specification sheet. Triumph has not yet confirmed the complete braking specification, suspension settings, kerb weight, chassis geometry or final electronics package for the production motorcycle.
The current Street Triple range already offers advanced features, but it would be premature to assume that every existing feature will automatically carry over to the 798. Details such as riding modes, traction control, cornering ABS and quickshifter availability should therefore be considered unconfirmed until Triumph publishes the complete specification.
Full Triumph Street Triple 798 Reveal Is Coming on November 17
Triumph has confirmed that the full Street Triple 798 specification will be revealed on November 17, 2026. This is when enthusiasts should finally get the production motorcycle’s official power, torque, weight, electronics and complete chassis specifications.
The motorcycle will also be displayed at major motorcycle events including EICMA and Motorcycle Live. For Indian buyers, however, there is still one major unanswered question: Triumph has not yet confirmed the India launch date or official India pricing for the Street Triple 798.
That means any price or launch estimates currently circulating should not be presented as confirmed information. The international reveal will provide the foundation for understanding where the new 798 sits in Triumph’s global performance-bike line-up, while India-specific information should follow separately.
Why the Street Triple 798 Could Be a HUGE Upgrade
The 2027 Triumph Street Triple 798 looks like a serious evolution of Triumph’s middleweight streetfighter formula. The new 798cc Moto2-derived engine brings a fresh performance foundation, while the new frame, chunkier swingarm and revised rear suspension show that Triumph has worked on the motorcycle’s dynamics rather than simply increasing displacement.
The styling transformation is equally significant. The new perimeter LED lighting, central main beam, sharper bodywork, 798 graphics and underbelly exhaust give the motorcycle a considerably more aggressive identity while preserving the compact streetfighter character that made the Street Triple famous.
The biggest question is still performance. Triumph has confirmed that the new Street Triple 798 is being developed as a more performance-focused machine, but the actual production power and torque figures remain hidden until November 17.
For now, three things are already clear: the engine is bigger, the chassis is substantially revised and the design has taken a major step forward. If Triumph manages to combine the stronger 798cc triple with the Street Triple’s trademark agility, the new motorcycle could become one of the most exciting middleweight naked bikes of the 2027 model year.
