2021 Triumph Speed Triple S [Model Overview]

2021 Triumph Speed Triple S

Triumph’s Heavyweight Naked: The 2021 Triumph Speed Triple S

The Triumph Speed Triple S is a British-made heavyweight naked roadster, and one of the most recognizable motorcycles in the 2021 Triumph line-up. It’s a versatile ride that can adjust its temperament to a wide range of situations. If you need a super sporty track bike, it won’t let you down, but if you need a more laid-back commuter, it’s got you covered there too.

Like many other Triumph Motorcycles, the Speed Triple S is powered by a liquid-cooled, 12 valve, DOHC, inline 3-cylinder engine, but the Speed Triple S packs a displacement of 1,050cc. The result is a power output of 148 horsepower and 86 lb-ft of torque. That power is kept under control with four selectable riding modes (Road, Rain, Sport, and Rider), switchable ABS and traction control, and cruise control.

Throw in a pair of fully adjustable Show front forks, a monoshock RSU, Brembo brakes, Pirelli Diablo Supercorsa tires, high-gloss cast alloy wheels, and a load of top-notch features like a USB charging point, LED DRLs, and a new 5” TFT display, and you’ve got a serious naked roadster on your hands.

For 2021, the Speed Triple S is available in two color options: Jet Black or Crystal White.

The 2021 Triumph Speed Triple S starts from $14,350 USD / $16,000 CAD.

2021 Triumph Speed Triple S Features


Full-color 5-inch TFT instrument display that presents both essential and additional rider information from the on-board computer, with three screen styles to choose from, all with high and low contrast settings, adjustable for optimum visibility.


Ergonomically optimized stylish new backlit switch cubes for fast intuitive access to bike functions, including 5-way joystick to navigate TFT instrument screen, riding modes button and new cruise control switch.


Easily accessed through the left hand switch cube, choose from four riding modes, Rain, Road, Sport and Rider-configurable. Each altering the throttle map, ABS and traction control settings to suit the conditions or desired riding style.


Fitted as standard for the first time on the Speed Triple, cruise control can reduce rider fatigue on long distance journeys and is quickly enabled and disabled via the left hand switch cube for additional convenience.


Daytime Running Lights are an impressive way of increasing your visibility with a distinctive light profile. These are incorporated into the headlamps, which are set characteristically low to reflect the Speed Triple’s nose-down focused attitude.


The latest Speed Triple is lighter, with an updated 1050cc engine, more responsive throttle, and improved gearbox to deliver even more power and the most agile, sharp and focused ride you’ve ever had on this explosive bike.


Improving the clutch ‘feel’ by reducing lever effort, bringing a lighter touch than you’d expect; perfect for long journeys or stop-start urban commutes.

Triumph Shift Assist

All-new Triumph designed system that enables smooth up/down gear changes without the use of the clutch, reducing rider fatigue.


Contemporary new black, race-style, freer flowing twin upswept silencers, with a larger bore and a more slender stainless steel end cap and aluminum heat shield.


There’s a more contemporary high-gloss finish to the Speed Triple cast alloy wheels, while high-spec Pirelli Diablo Supercorsa tyres and twin disc front brakes with Brembo Monobloc calipers provide an even greater feel and control.
