2021 Triumph Speed Twin

Triumph’s Stylish Modern Classic: The 2021 Triumph Bonneville Speed Twin

In any configuration, the Triumph Bonneville is the quintessential British motorcycle. However, for those who want the perfect combination of classic heritage and modern performance, the Speed Twin is the only model that should take your fancy in the 2021 Triumph line-up. It takes everything we love about modern Triumph motorcycles, but installed in a stylish, retro chassis.

The heart of the Speed Twin is Triumph’s high-powered 1200cc liquid-cooled, 8-valve, parallel twin Bonneville engine, uprated with Thruxton tuning. In terms of power, the Speed Twin produces 95 horsepower and 82 lb-ft of peak torque. The power is delivered to the rear wheel via a six-speed transmission and kept under control using Ride-by-Wire technology, switchable traction control, and ABS, a torque-assist clutch, and three riding modes.

Aside from the sleek and classic styling of the Speed Twin—which includes a signature 3.8-gallon tank, upswept exhausts, a bench seat, and sculpted bodywork—other goodies include stylish instrumentation, LED lighting, a tire pressure monitoring system, immobilizer, and USB charging port. Plus, Triumph offers more than 70 accessories for riders to choose from.

For 2021, the Speed Twin is available in three color options: Silver Ice / Storm Grey, Korosi Red / Storm Grey, and Jet Black.

The 2021 Triumph Speed Twin starts from $12,200 USD / $13,400 CAD.

2021 Triumph Speed Twin

2021 Triumph Speed Twin Features


At the new Speed Twin’s heart is an updated high power 1200cc Bonneville twin engine with the celebrated Thruxton performance tune that peaks at 97PS @ 6,750rpm. Evolved from the Thruxton powerplant, this enhanced engine is a low inertia high performance 6-speed 8-valve parallel twin that now features a magnesium cam cover, a revised clutch assembly and mass-optimised engine covers.


This is a new kind of performance modern classic, with an exhilarating torque delivery from low down and then right through the range. Torque peaks at 82.6 FT-lbs (@4,950rpm), matching the output of the Thruxton R, and a whole 40% more than Triumph’s latest Street Twin model.


Built to a high performance specification, the Speed Twin noticeably showcases twin Brembo front brakes. In addition, lightweight cast aluminium wheels and high specification Pirelli Diablo Rosso 3 tyres both contribute to the Speed Twin’s class leading agile and dynamic handling. An Anti-locking Braking System (ABS), and traction control that is easily switchable via the left hand switchcube, deliver enhanced control of the Speed Twin’s high torque performance whatever the riding conditions.


This incredible motorcycle has a thrilling deep British roar to match the Speed Twin’s legendary name. The distinctive twin black megaphone upswept sports silencers produce a wonderful throaty sound which is all capably supported by Triumph’s innovative uninterrupted flowing exhaust header run, with hidden cat box, so the lines are as smooth as the ride itself.


The Speed Twin’s newly-designed chassis has been evolved from the Thruxton R and crafted to provide a new benchmark in agile, dynamic riding. Working together with this tailored new frame are high specification front and rear suspension, tuned to deliver a precise modern roadster ride with confidence-inspiring intuitive feel, whether you’re commuting, traveling longer distances or just riding for the fun of it.

For maximum possible rider fun, comfort and control, the Speed Twin benefits from a host of advanced technology. Three rider modes – Road, Rain, and Sport – that adjust throttle map and traction control settings to suit conditions and rider preference, the bike’s LED lighting brings greater durability and power efficiency, and the lighter feel of the torque-assist clutch delivers more comfort over long journeys and stop-start urban commutes. In addition, feature-packed twin clocks, immobilizer and a USB socket are all included as standard.


A huge aspect of the Speed Twin’s allure is its beautiful custom classic looks, which is why the detailing and finish that you’ll find on the Speed Twin are nothing short of category-leading. Specially-crafted brushed aluminum features include mudguards, throttle body covers, side panel finishers, and heel guards. The magnificent aluminum theme continues with a bright anodized forged aluminum headlight bracket and clear anodized aluminum swingarm.


Triumph’s timeless DNA is at the core of the Speed Twin’s modern classic looks, and this is blended together with a more contemporary stripped-back custom style and poise. Original equipment features also include the Speed Twin’s 14.5-liter signature sculpted fuel tank, the comfortable stylish bench seat, minimal front mudguard & rear end setup with elegant rear light, and bar end mirrors.
