Triple-Cylinder Handling Precision
The Street Triple 765 RS is the sharp end of Triumph's middleweight naked family, and the whole bike is built around that 765 cc inline-three. It makes 121 hp and 57 lb-ft, but the number that matters is the shape of the delivery: a rising, urgent torque curve that pulls hard from low in the rev range instead of an ironed-out flat line. Wrap that engine in a 412 lb chassis with a Showa Big Piston Fork (BPF), an Öhlins STX40 shock, Brembo M50 calipers, and Pirelli Diablo Supercorsa SP rubber, and you get real trackday hardware straight off the showroom floor.
It rides lighter than the spec sheet suggests. The RS ships with ABS, traction control, ride modes, and wheelie control, so the electronics have your back without smothering the fun, and the chassis rewards a rider who works the corners rather than just chasing straights. The mechanicals are generally well-sorted and hold up to hard use. The honest caveat is the electrical side: the TFT cluster has a real failure history, and because the immobilizer lives inside it, a dead screen can strand the bike. Buy with eyes open and check the history.

The named systems that set this bike apart — and what each one does for you.
Braking
Swing a leg over and the 32.5 in seat feels tall but narrow, so most riders still get a confident foot down, and the reach to the bars puts you slightly forward and ready to attack. Fire it up and the triple is the star of the show: a hard mechanical howl on the pipe that turns into a genuine soundtrack when you open it up, one of the best noises in the class. Down low the motor is smooth and civilized with barely any buzz through the pegs and bars, then it wakes up and gets vocal higher in the range. At real road pace the naked stance puts wind straight into your chest, and that pressure does its job. It makes 60 mph feel eventful and keeps your license intact without dulling the ride. The whole machine feels tight, honest, and eager under you.
This section isn't my own test ride. It's what I've picked up from riders over years of paddock talk, owner conversations, long back-and-forth email threads, and the messages that land in my inbox once someone has actually lived with the bike. For the Street Triple 765 RS the pattern is consistent: deep affection for how it rides, set against a short, specific list of gripes about comfort and daily manners.
Riders consistently rate the brakes among this bike's high points. The front setup pulls the RS down hard and stays progressive, and owners report no fade even on long, sustained mountain descents. The finish earns steady praise too: machined footpegs, metal-housed LED indicators, adjustable levers, and paint that still looks right after three years and more, with no corrosion turning up. Many treat the RS as a genuine all-rounder, happy doing a weekday commute, a canyon run, and the occasional track day, with better than 185 miles (300 km) from a tank and roughly 50 mpg in mixed use. And despite the odd reported fault, most owners find the engine tough, plenty of them logging 12,000 to 22,000 miles without trouble.
The complaints cluster around comfort and daily use. The suspension is tuned for the track, and riders find it firm to the point of punishing on broken or rough surfaces. Sitting in traffic brings another common gripe: the exhaust routing pushes real heat onto the rider's legs during stop-and-go crawling. The stock bar-end mirrors draw near-universal criticism, buzzing enough at most engine speeds that rearward vision suffers, so swapping them is usually the first thing an owner does. Several also find the butterfly-style tach hard to read at a glance, with the clock and temperature readouts too small to catch on the move and the bar clamp throwing reflections into the screen.
Ownership carries a handful of running costs riders flag. Service intervals sit at an oil change every 6,000 miles (10,000 km) and a valve check every 12,000, and owners note that main-dealer visits aren't cheap, partly because resetting the service light needs a special electronic tool. The rear tire is another expense, with the stock Supercorsa worn out in roughly 3,000 miles (5,000 km) of spirited riding. And there's a recurring practical grumble: nowhere to strap luggage to the tail, no hook, bar, or bracket to secure a bag for a longer trip.
TFT display total failure or partial failure
The TFT instrument cluster can fail completely (dead screen) or develop partial failures (white patches, dead pixels, flickering). Critical: the immobilizer is integrated into the cluster — a total failure prevents the bike from starting. The cluster housing is bonded shut, making component-level repair impossible. Replacement cost: approx. £1,000–1,800+. The 2017–2019 models are more prone to total failure; 2020+ models more often show partial white-patch failures. Triggers include battery replacement, moisture ingress, and age. Triumph has issued goodwill replacements in some cases but has not acknowledged a systemic defect. A dedicated poll on triumphrat.net documents a significant number of affected owners across multiple model years.
Catastrophic inlet valve head detachment
TWO separate test bikes suffered identical catastrophic engine failures. In both cases, an inlet valve head detached from its stem, fell into the combustion chamber, and destroyed the piston and cylinder bore. First failure at 19,680 km (right inlet valve, middle cylinder). Second failure at 29,035 km on a replacement bike (different cylinder). Triumph investigated four engines from different production batches with metallurgical analysis and extreme dyno testing — "no abnormalities could explain the damage." Triumph states the worldwide valve-train complaint rate is below 0.02%. While extremely rare in the broader fleet, the occurrence of two identical failures on two successive test bikes is significant.
Engine cutting out randomly while riding
Multiple owners report the engine cutting out randomly while riding — including at constant speed, during braking, and after acceleration. Display stays on and no error codes are stored, making diagnosis difficult. Confirmed root causes across different cases include: faulty stator/pickup coil, dislodged fuel pump seal causing intermittent fuel delivery, and ECU map issues (resolved by dealer reflash). Affects primarily 2020 and 2022 models based on forum reports.
Premature headlight bulb failure
Both dipped-beam bulbs were found burned out at the 20,000 km service (mismatched replacement bulbs found — white and blue). Some forum reports of repeated bulb failures. Suspected root cause in severe cases may be voltage regulator instability.
Quickshifter intermittent failure and false neutrals
The Triumph Shift Assist (TSA) quickshifter can exhibit intermittent failures, particularly on the 1st-to-2nd upshift, resulting in false neutrals or missed gears. Some units had a faulty quickshifter sensor that Triumph revised during production. Known remedies: ECU reset (battery disconnect + cycling through all gears), software reflash, and sensor replacement. The first oil change (from factory fill to service oil) reportedly improves shifting behaviour.
Front brake disc warping or pad deposit causing pulsation
Some owners report pulsation through the front brake lever, particularly during hard braking at higher speeds. Can be caused by actual disc warping or by uneven brake pad material deposits on the disc surface (more common). Cleaning discs and pads with acetone and a re-bedding procedure often resolves deposit-related pulsation. Some owners have had discs replaced under warranty.
Clutch damper springs loosening, causing grinding/rattling noise
At around 24,659 km, unusual grinding noises from the clutch area when cold. Three of six clutch damper springs were found to be too loose. Required clutch basket replacement (covered under warranty). Some owners also report a generally noisy clutch that Triumph considers within normal operating parameters for a wet clutch.
Jerky throttle response at low RPM and small throttle openings
A well-documented characteristic of Triumph's ride-by-wire fuel-injected triples: the throttle produces a jerky on/off transition in the 0–5% throttle range at low RPM (idle to ~5,500 rpm). Particularly noticeable in stop-and-go traffic and parking manoeuvres. "Road" mode is smoother than "Sport" but the issue persists. Aftermarket solutions include G2 Throttle Tamer tubes, ECU remapping (TuneECU), and throttle cable free-play adjustment. A professional dyno tune is considered the only complete fix. Some owners consider this a design characteristic rather than a defect.
Stock bar-end mirrors vibrate excessively at speed
The OEM bar-end mirrors on the RS model vibrate significantly at most engine speeds, rendering rearward visibility poor above approximately 60 km/h. This is one of the most commonly cited owner complaints and a near-universal first modification. Most owners replace them with aftermarket units (Rizoma, CRG, etc.). Note: this is an RS-specific issue — the R model uses conventional stalk mirrors that do not exhibit this problem.
Oil weeping from alternator cover gasket
Minor oil weeping from the alternator cover gasket is a widely reported issue. Dealers confirm "it happens on a lot of these bikes." Root cause is frequently undertorqued bolts from the factory — mechanics report bikes arriving for the first service with alternator cover bolts at 6 Nm instead of the specified 10 Nm. The leak is typically a slow weep (one drop after each ride) rather than a heavy drip. Oil levels usually remain stable. Retorquing the bolts to specification resolves the issue in most cases; some bikes require gasket replacement. Affects all trim levels (S/R/RS).
Cam chain rattle/slap on cold startup
The hydraulic cam chain tensioner can bleed down after the bike sits for extended periods (overnight or longer), causing a noticeable chain rattle on cold startup until oil pressure builds. Common to many Triumph triple engines. Aftermarket manual cam chain tensioners available as a permanent fix. Dealers report that many 765 engines develop tight exhaust valves, which can exacerbate perceived engine noise.
