Speed Triple 1050 (MY2011)

Triple Character, Real Grunt

The Machine's Character

The Speed Triple 1050 is built around one idea: the muscular 1,050 cc inline-three. That big triple gives you 83 lb-ft of torque that arrives early and keeps climbing, plus a sound that belongs to no V-twin and no four. With 136 hp on tap it never runs short of top-end for a 152 mph machine, but the real story here is character. This is the premium end of the naked class, where build quality and a genuine sense of personality count as much as the raw numbers. It feels like a motorcycle with an opinion, and that opinion is worth listening to.

On the road it stays light and honest. The controls are easy, the chassis is agile for a 467 lb bike, and it settles into fast corners without asking much of you. It rewards riders who want feel over gadgetry, because there is little electronic help on hand here. The caveat is real. The 32.5 in seat sits tall, fuel economy runs around 36 mpg, and the single-sided rear hub bearings are worth watching as the miles climb. Buy one for its character, keep it maintained, and it ages into something genuinely special.

The Voice of Experience

Portrait of NastyNils

The test ride

Thumb the starter and the triple clears its throat with a hard, mechanical growl that sharpens as the revs rise. You sit fairly upright with the bars close and the pegs set back enough to load the front, so your weight goes where you want it through a corner. There is vibration through the pegs and tank, the good kind that tells you the engine is working rather than the kind that numbs your hands. At real road pace the wind hits your chest and shoulders and does its job, making 70 mph feel like an event and keeping your license out of trouble. Ground clearance is generous, so you run out of nerve long before you run out of lean. The whole bike feels tactile and deliberate, the way a good naked should.

The Truth on the Street

I didn't build this from one afternoon on the bike. It comes from years of hearing riders out: owner conversations, questions that land in my inbox, and the back-and-forth that fills a garage evening. On the Speed Triple 1050 the pattern rarely shifts. There's deep respect for the motor and the way it's put together, shadowed by a few gripes that keep resurfacing.

What Owners Keep Coming Back To

The three-cylinder engine runs away with most conversations. Riders describe it as a character trait more than a horsepower figure, prizing the fat torque low down and the way it keeps building without being flogged. That intake and exhaust voice comes up again and again as something no twin or four can copy. Close behind sits the build. Many owners rank the fit, finish, and paint among the finest to leave the factory, and they keep circling back to it. The bike also earns steady marks as easygoing daily company, roomier and less punishing than the hardest nakeds in the class. Its angular twin lights, exposed frame, and single-sided swingarm draw a loyal following too, credited with real presence in a crowd of near-identical shapes.

The Gripes That Keep Surfacing

The transmission takes the loudest criticism by some distance. Owners talk about stiff, obstinate shifts, at their worst picking through the lower gears, and the occasional change that simply won't drop into place, neutral included. Riders on the earlier machines stay watchful of the charging system too, a worry that has trailed these bikes for a long time. The lesser grumbles are steadier than sharp. A few point to the lack of any wind shelter, which wears on you over long highway runs. Others note it never gained the lean-sensitive rider aids that arrived on later competition, and that its top-end output sits under the strongest bikes in the class.

Known issues

  • Transmission detent arm spring incorrect thickness

    drivetrainoccasionalRecall

    The transmission detent arm spring was manufactured at an incorrect thickness on a production batch. Risk of poor-quality gear changes and transmission disengaging while riding. **Official safety recall.**

  • Neutral indicator switch incorrect washer thickness

    drivetrainoccasionalRecall

    A washer of incorrect thickness between the neutral indicator switch and the gear selector drum can cause the neutral indicator to falsely show the bike is in neutral when it is not. Releasing the clutch in this condition can cause unexpected lurching and crash risk. **Official safety recall.**

  • 2011-only front brake rotor warping

    brakesoccasional

    2011 examples specifically reported warped front rotors (Sunstar disc supplier issue cited as a wider-industry pattern in 2011). Some replacement floating discs from grey-market sources reportedly assembled incorrectly. Triumph subsequently moved to Brembo monobloc on R variants from 2012 and revised the brake package for 2016.

  • Datatool S4 alarm internal battery leak

    electricsoccasional

    The Datatool S4 alarm kit fitted by Triumph dealers as an accessory has an internal NiMH battery that can leak onto an unprotected circuit board. Resulting corrosion can interrupt ignition and cause engine stall. **Equipment recall — applies only to bikes that received this dealer-fitted accessory.**

  • Rear wheel hub bearing premature wear

    chassisoccasional

    The single-sided swingarm rear hub uses needle bearings that can fail before sealed bearings would in a conventional dual-sided design. Wide range of reported failure mileages (15,000–56,000 miles); inadequate factory grease and bearing quality cited by long-term owners.

  • ABS warning light triggered by sensor air-gap or connector corrosion

    electricsoccasional

    ABS warning light triggered by sensor air-gap out of specification (front 0.1–1.5 mm, rear 0.5–1.5 mm), connector corrosion, or failed sensor. Speedometer can freeze when the rear ABS sensor fails because the speed signal on these bikes is derived from the rear-wheel ABS sensor.

  • Starter sprag clutch failure

    engineoccasional

    The starter sprag clutch (one-way clutch between starter motor and crank) can fail, particularly when battery voltage is marginal at start. Symptoms: clicking sound on start, starter spins without engaging, can strip starter motor shaft teeth and contaminate the starter cover with metal shavings. Early 1050 examples reportedly used a smaller sprag than later units; later runs are less affected but pattern persists.

  • Charging system: regulator/rectifier failure leading to stator failure

    electricsoccasional

    The OEM SCR-shunt regulator/rectifier (R/R) generates excess heat, eventually fails, and on failure damages the stator. Pattern: stator failure 6–12 months after R/R replacement if root cause (poor connectors, shunt design) is not addressed. Triumph issued a service bulletin for upgrade to MOSFET-style FH012AB or equivalent. **This is a separate issue from the 2017 SB552 wire-routing recall**, although both touch the same charging subsystem.

  • Cam chain tensioner premature wear

    engineoccasional

    The hydraulic automatic cam chain tensioner can wear prematurely. Aggressive engine braking accelerates damage. Symptoms: "cam chain slap," rattling under load at higher revs, ticking noise. Severe cases produce aluminum filings in cases. Aftermarket manual tensioners (often GSX-R-derived) are common owner remedies.

  • Clunky gearbox, particularly neutral → 1st and 1st → 2nd

    drivetrainoccasional

    Universally reported gearbox feel: "notoriously clunky" shifts, particularly on cold engines and low-speed shifts. Some 2012–2013 examples additionally suffered the neutral-indicator washer fault and the transmission detent-arm spring fault (both officially recalled). False neutrals also reported on 2016+ bikes when aftermarket quickshifter rods foul the shift arm, and when the front sprocket nut works loose.

  • Throttle hesitation at low RPM and small throttle openings

    fuel systemoccasional

    Touchy or jumpy throttle below approximately 25 mph or 4,000 rpm, particularly when rolling on in turns or in slow traffic. Root cause linked to ECU map switching from throttle-position-sensor (TPS) to manifold-air-pressure (MAP) at low RPM, occasionally to oxygen-sensor drift. Pre-2016 cable-throttle behaviour; 2016+ ride-by-wire is generally smoother but some reports of aggressive throttle response in 1st and 2nd gears persist.

  • Premature front fork seal leaks

    suspensionoccasional

    Fork seal leaks reported at low mileages (10,000 km / approx. 6,000 miles) and after winter storage. Some recurrences shortly after dealer reseals, with anecdotal reports of reused parts not being properly cleaned.

  • Thin tank paint, mirror-stem rust, frame paint vulnerability

    bodyworkoccasional

    Tank paint reported as relatively thin compared to Japanese rivals. Mirror stems develop surface rust after several years. Frame and swingarm paint vulnerable to chipping. Fork-leg corrosion and underbelly engine paint peeling reported on long-ownership and salt-belt bikes.

  • Valve cover gasket weeping (left side of head)

    engineoccasional

    Light oil film on the left side of the cylinder head, particularly around the four "half-moon" rubber plugs at the cam ends that require RTV sealant on reassembly. Loose valve-cover bolts can contribute. Cosmetic rather than performance impact.
