Unmistakable Modern Sports Classic Style

Modern classic roadster design has reached a new benchmark thanks to the evolution of the original high-performance icon.

Features and Updates

Due to its category-defining premium finish and detailing, class-leading handling, thrilling and responsive engine, cutting-edge rider technology, and stunning, contemporary custom style, the Speed Twin, introduced in 2018, established the standard for a Modern Classic performance roadster should ride and feel.

The Speed Twin, an award-winning motorbike, has been popular with customers. The Speed Twin featured the modern custom look and engaging ride of the Street Twin, with even more premium and attractive features and touches. It was known for possessing the power and torque of the Thurston R in an even more approachable setup.

And now, for 2021, the Speed Twin provides an update in every area—from handling, technology, and style to power and performance—making it the ideal marriage of personality, style, and actual sporting performance.

Higher Performance

The Speed Twin’s charming 1200cc High Power Bonneville twin engine has undergone significant updates for 2021 and is now fully compliant with Euro 5 in terms of performance and emissions. With 100PS at 7,250 rpm and 3PS greater peak power than the previous generation, the engine now has more substantial midrange power.

The 2021 Speed Twin also features a broader torque curve, with a peak torque of 112Nm reaching more than 500rpm lower down the rev range compared to the previous generation, in addition to the compelling and linear power delivery.

Another improvement to the Speed Twin engine’s responsiveness is the 17% reduction in inertia made possible by a redesigned, lighter alternator and crankshaft. These allow the engine to rev more complexly and longer than the previous version, with a red line now 500 rpm higher. The list of performance improvements is completed with new high-compression pistons, updated ports, and a new cam profile.

The new brushed stainless steel megaphone twin upswept sports silencers, which have been meticulously constructed for a deep, throaty roar to match the Speed Twin’s illustrious moniker, amplifying the unmistakable sound of the Bonneville Twin. The catalyst box is skillfully hidden by the inventive and continuous exhaust header run, resulting in the recognizable clean-line “straight-run” look.

The high initial major service interval of 10,000 miles/16,000 kilometers helps to keep ownership costs low for all of the Triumph Modern Classic models.

Better handling

The new generation Speed Twin benefits from several substantial enhancements for an even more precise, elegant, and dynamic ride, adding to its well-known reputation for excellent, comfortable handling.

With higher-spec upside-down 43mm Mar Zocchi front forks and cartridge damping, the Speed Twin is brand-new for 2021 and offers a more secure and pleasant ride with 120mm wheel travel. These are ideally suited to the dual rear suspension units, carefully calibrated for even superior handling and the ideal ride for a contemporary roadster, and include adjustable spring preload and 120mm of rear wheel travel.

Brembo 4-piston M50 radial Monobloc front brake calipers and dual 320mm Brembo discs, newer, higher-specified components that further increase the next generation Speed Twin’s braking capabilities. These provide a sharper initial brake bite, a more sumptuous feel, and superior fade characteristics when combined with the Nissin 2-piston floating rear caliper with 220mm disc and ABS installed as standard.

New cast aluminum wheels, 17″ in size front and back, with a lightweight 12-spoke design, are also standard equipment for the 2021 model, providing remarkable grip, accuracy, and high-speed stability.

The Speed Twin is a balanced motorbike that offers a natural and self-assured riding experience. With an easily accessible 809mm seat height, a narrow stand-over width, tapered handlebars, and a comfortable roadster foot-peg position 38mm farther front and 4mm lower than the Thurston, the ergonomics are precisely suited to provide the rider a more relaxed riding posture.

Enhanced Technology

A sophisticated ride-by-wire system that assures accurate throttle control and offers three riding modes—Rain, Road, and Sport—is one of several rider-focused technologies in the next-generation Speed Twin. These have been improved for 2021, allowing the rider to customize the traction control and throttle response settings.

To adapt to any change in the riding environment and to maximize rider confidence and safety, the riding modes may be changed at the press of a button while the rider is moving. Through the instrument menu, the rider can freely decide to turn off the traction control.

As long as market regulations allow it, the bike has indicators, an LED rear light, and a distinctive LED Daytime Running Light (DRL) built into the headlamp.

The scroll button on the handlebar is used to access the digital menu system built into modern 3D clocks. It gives the rider access to traction control settings, a TPMS indication if one is installed as an accessory, two trip settings, fuel level, and range to empty. It also displays average and actual fuel usage.

Other rider-focused equipment includes a USB charging port beneath the seat, a tire pressure monitoring accessory, and an immobilizer with a transponder built into the pricey Triumph key.

More Premium Style and Detailing

The new 2021 Speed Twin is even more gorgeous and has even more sophisticated accents. It mixes Triumph’s classic DNA with a contemporary stripped-back bespoke style and elegance.

Along with its trademark 14.5L tank with knee indents, lovely bar end mirrors, sculpted side panels, and chic bench seat, the Speed Twin is distinguished by its new 12-spoke cast wheels, twin upswept sporty silencers, and brushed stainless-steel headers.

Brushed aluminum front and rear mudguards with new mounts, side panel finishers, and heel guards are just a few of the high-end accents and finishes consistent throughout the bike. The new anodized headlight mounts, painted headlamp bowl, vintage Monza fuel cap, and clear anodized aluminum swing arm are all quality finishing touches and features.

The Speed Twin is offered in three paint colors for 2021: the brand-new, glistening Red Hopper scheme, the chic Matt Storm Grey with subdued yellow accents, or the time-honored Jet Black.

The Genesis of a Motorcycle Icon

The original 1938 Triumph Speed Twin, the first successful parallel twin engine ever packed into a chassis that changed the face of motorcycles, was a revelation to ride. Its exceptional responsiveness and smooth dynamic handling made Triumph the top motorcycle brand in the world for performance and handling, establishing the standard for all that came after. It also gained a reputation as the first proper “rider’s bike” worldwide.

The new Speed Twin redefines the standard for 2021 with its perfect blend of torque-rich performance, elegant and dynamic handling, and stunningly modern bespoke motorcycle character.

50+ Custom Accessories

The 2021 Speed Twin provides users with more than 50 bespoke attachments to further customize their bike’s appearance, functionality, and security. These include heated grips, knee pads, head bolt covers, sump plates, multi-function LED indicators, quilted seats and luggage, and many more.

To ensure flawless integration and exceptional longevity, all authentic Triumph accessories have been created and developed in tandem with the bike itself to the same high standards. They also all come with the same two-year unlimited mileage warranty.


The new 43mm Mar Zocchi upside-down cartridge forks and dual rear shocks on the Speed Twin are tuned to provide class-leading handling, providing 120mm of regulated damping and a ride that inspires confidence.


Robust new premium grade Brembo four-piston M50 radial Monobloc calipers, high-performance 320mm floating discs, and the latest ABS generation all contribute to confident and secure braking.
