Triumph Street Triple RS 2025 — Specifications

Can a road bike truly possess the soul of a race machine? Triumph seems to answer yes, a little more each year with its Street Triple RS. This roadster, which has fueled the rivalry with the KTM 890 Duke R for years, doesn’t just evolve; it becomes more radical. Proof of this is the 2025 version, which now delivers 130 horsepower at 12,000 rpm, a figure that definitively shifts the category into a hyper-sportive register. It’s no coincidence that this 765 cm3 three-cylinder engine is the same one that screams in Moto2, even if, of course, the civilian version retains a relative degree of sanity for road use.

Under the 15-liter fuel tank, the engineering is anything but cosmetic. The compression ratio rises to 13.25:1, and the pistons, connecting rods, and camshafts are new. The result is a more impactful engine, with 80.4 Nm of torque that arrives forcefully and a desire to rev that never falters. Coupled with the six-speed gearbox and the bi-directional quickshifter, the English trio becomes a true acceleration weapon. This is far from a simple aesthetic update; it’s a mechanical recalibration for demanding riders.

The chassis naturally follows this increase in power. The perimeter aluminum frame now accommodates high-end running gear. At the front, the 41 mm Showa inverted fork is fully adjustable, while at the rear, the Öhlins STX40 works with a gullwing swingarm for exemplary traction. Braking, entrusted to Brembo Stylema calipers on 310 mm discs, inspires absolute confidence. With a declared weight of 188 kg fully fueled and a 836 mm seat height, the RS remains surprisingly agile, ready to pivot on a thought.

The electronics are not to be outdone, with a 5-inch TFT dashboard controlling customizable riding aids, including traction control and wheelie control. The five riding modes, including a Track mode, allow you to tame this power. This is the entire philosophy of this Triumph Street Triple RS: to offer track precision without sacrificing daily usability. Faced with a more raw and nervous KTM 890 Duke R, Triumph plays the card of sophistication and finish, at a price that flirts with 12,800 euros.

So, who is this machine for? Clearly for the track enthusiast who wants an explosive track-day base, or for the sporty touring rider seeking the most technically advanced roadster. This is not a bike for beginners; its lively character and power demand maturity. The Street Triple RS 2025 is not a revolution; it is a logical and relentless evolution. It proves that at Triumph, Moto2 lineage is not a marketing argument, but a mechanical reality that you feel with every throttle opening. A superb machine, simply.
