Triumph Street Triple 765 RX Top Speed, Specs & Review
TL;DR
- The Street Triple 765 RX makes a claimed 128.2 hp at 12,000 rpm and 59 lb-ft at 9,500 rpm from the same 765cc triple as the RS.
- US pricing starts at $14,495, a $950 bump over the RS for Öhlins NIX30 front suspension, clip-on bars, and premium trim.
- No independent instrumented top speed or 0-60 test exists yet for the RX; the closely related RS ran 0-60 mph in 3.10 seconds and a 150.4 mph top speed in third-party testing.
- Wet weight is 414.5 lb and seat height is 33.0 inches, both unchanged from the RS spec sheet.
- It’s a 2026-model-year-only special edition; US units start arriving in December 2026 ahead of a revamped Street Triple platform for 2027.
How Fast Is the Triumph Street Triple 765 RX?
Nobody’s strapped a RaceLogic box to a production RX yet, so there’s no independently verified 0-60 or top speed figure for this specific bike as of this writing. What we do have is the RS, which shares the RX’s frame, engine tune, and gearing.
MotoStatz clocked the Street Triple 765 RS at 0-60 mph in 3.10 seconds, 0-100 km/h in 3.38 seconds, and a top speed of 150.4 mph, with the quarter mile going by in 10.79 seconds at 132 mph (MotoStatz, 2024). This is RS data, not an RX-specific test; treat it as a close proxy, not a confirmed RX figure.
Since the RX runs the identical 128.2 hp engine and final drive as the RS, expect numbers in that same neighborhood, maybe a couple tenths quicker to 60 thanks to marginally lighter unsprung mass from the Öhlins fork. Take that as an educated guess, not a claimed figure. This article will get flagged for an update once a real test publishes.
What’s Actually Different Between the RX and the Standard RS?
The RX isn’t a new engine or frame. It’s the RS chassis with the suspension and cockpit sharpened for track days, according to Triumph’s own spec comparison (Motorcycle.com, 2025).
Triumph swaps the RS’s Showa Big Piston Fork for a fully adjustable Öhlins NIX30 upside-down fork with 4.5 inches of travel, while the Öhlins STX40 piggyback shock carries over unchanged from the RS.
Clip-on handlebars replace the RS’s tubular bar, mounted to a machined top yoke with the RX logo laser-etched into it. Brakes, wheels, and the frame itself are identical to the RS. You’re paying the $950 premium almost entirely for that fork and the riding position change, plus the Matte Aluminum Silver and Diablo Red paint that nods to the 2015 Street Triple 675 RX.

That 128.2 hp figure puts it ahead of most middleweight nakeds in the showroom right now, and the powerband pulls cleanly from well under 6,000 rpm all the way to the 12,500 rpm limiter. It’s not a peaky engine that only wakes up near redline. You get real midrange shove for highway passes, then a hard top-end rush if you keep the throttle pinned.
Suspension and Brakes: What You’re Paying For
The RX’s suspension upgrade is the single biggest functional difference from the RS, and it’s where the extra money actually goes.
Up front sits a fully adjustable Öhlins NIX30 fork with compression, rebound, and preload adjustment across 4.5 inches of travel. The rear keeps the RS’s Öhlins STX40 piggyback shock, also fully adjustable, with 5.16 inches of travel.
Braking is unchanged from the RS: twin 310mm floating discs with Brembo Stylema four-piston radial monobloc calipers and a Brembo MCS radial master cylinder up front, plus a 220mm single disc with a single-piston Brembo caliper out back.
Cornering ABS comes standard, with a dedicated track calibration that pulls back intervention for riders pushing hard on a closed course.
If you’ve ridden an RS on a Showa BPF and then thrown a leg over the RX, the difference shows up mid-corner: less dive under trail braking, more precise feedback when you’re loading the front tire hard on the way into an apex.
Who Should Buy the Street Triple 765 RX?
This bike is built for riders who already know how to use a middleweight naked’s power and want sharper hardware underneath them.
The 33-inch seat height and clip-on riding position put more weight on your wrists than the RS, which matters on a 45-minute commute but disappears once you’re leaned over on a back road or lapping a track day.
Triumph is building this as a one-year-only send-off before the Street Triple platform gets revamped for 2027, so anyone chasing the current-generation triple in its most track-focused street trim needs to order before December 2026 production winds down.
It’s not the right pick for a new rider’s first bike or for someone who wants an upright commuter; the RS or the base Street Triple 765 covers that job better and cheaper.
