Triumph Street Triple 798 RS: Moto2-Derived 138 HP Naked Previewed

Part of Throttle Times’ live coverage of EICMA 2026.

For seven years, Triumph’s 765cc triple has sat unchallenged as the benchmark of middleweight roadster precision. By supplying every single machine on the FIM Moto2 World Championship grid since 2019, Hinckley accumulated millions of telemetry kilometres under sustained 14,000 rpm race stress. But with Euro 5+ emissions strangling cylinder filling and Japanese rivals pushing displacement past 890cc, the venerable 765 platform was approaching the physical ceiling of its road-going torque curve.

At EICMA 2026, Triumph showed its hand. Positioned prominently under the Milan lights, the British marque previewed the next-generation 2027 Street Triple 798 RS. This is not a cosmetic facelift: it represents a decisive displacement jump to 798cc, drawing directly from Hinckley’s latest Moto2 development program to deliver more mid-range punch, sharp new electronics, and an even tighter chassis package.

Moto2 Displacement Bump: 798cc Triple Delivering 138 HP

The 2027 Street Triple 798 RS increases engine displacement to 798cc through a longer stroke and re-profiled combustion chambers, targeting approximately 138 metric horsepower (101.5 kW) at 12,250 rpm and 85 Nm of torque at 9,500 rpm.

Crucially, the torque curve fills out significantly between 5,000 and 8,000 rpm, addressing the only criticism seasoned road riders ever leveled at the high-revving 765 RS. The engine breathes through redesigned throttle bodies and exhausts via a compact, mass-centralised underslung silencer that replaces the previous low-side can, cleaning up the lines around the revised gullwing swingarm.

“Our Moto2 engine development taught us that cylinder scavenging at mid-stroke velocities determines lap consistency far more than chasing the final three horsepower at redline,” noted a Triumph engineering lead on the EICMA stand. “The 798cc architecture delivers immediate punch off the apex without forcing the rider to constantly dance on the gear lever.”

Chassis Geometry, Stylema Calipers, and Showa/Öhlins Suspension

The 798 RS retains Hinckley’s razor-sharp handling DNA with a revised twin-spar aluminum frame offering 6% increased torsional stiffness, paired with top-shelf Brembo Stylema radial calipers clamping 310mm floating discs.

Suspension components mirror pure track-day pedigree: fully adjustable 41mm Showa Big Piston Forks (BPF) handle the front end, while a bespoke gold Öhlins STX40 piggyback monoshock governs the rear. Wet weight is targeted at 180 kg with a full 15-litre tank. A restyled front flyscreen incorporates sharper, more menacing dual LED projector headlights with integrated eyebrow daytime running lights, framing an updated 5-inch full-colour TFT dash with dedicated Track and Lap-timer displays.

The Rider’s Trade-Off: Screaming Redline vs. Everyday Usability

The core mechanical sacrifice of moving from the 765 to the 798 architecture is a slightly lower absolute rev ceiling in exchange for fatter low-to-mid-range torque.

Purists who relished wringing the 765 RS past 13,000 rpm will notice the 798 shifts its powerband slightly lower in the rev range. In practical European riding—tackling hairpins on Alpine passes or overtakes on B-roads—the extra 5 Nm and broader torque plateau make the 798 vastly faster and less fatiguing. However, for hardcore track riders who live exclusively above 11,000 rpm, the engine delivers a slightly more linear, less frantic top-end sensation.

Market Context and European Arrival

Full technical homologation and European dealership delivery schedules are slated to be revealed on November 17, 2026, with market launch expected in March 2027 at an estimated starting price of €13,995. Following hot on the heels of the Triumph Thruxton 400 prototype and recent updates to the long-range Triumph Tiger 1200, Hinckley is deliberately defending its middleweight territory against the Yamaha MT-09 SP and Ducati’s newly revamped Streetfighter families.

What We Know

• All-new 798cc Moto2-derived triple platform targeting ~138 hp and ~85 Nm of torque.
