IT WAS, in many ways, the bike that gave birth to Triumph motorcycles as we know them. The first Speed Twin was unveiled just before World War II and went on to become a global sales sensation after the war, launching the British motorcycle industry into a period of world domination.
The Speed Twin was not Triumph’s first twin. That spot in history is owned by a 650 twin — the imaginatively named 6/1 of 1933 — but it was the 498cc Speed Twin that seemed to hit the market at just the right time. Good for 90mph and lighter than many of the single-cylinder British bikes doing the rounds at the time, it was a huge hit in the USA. So popular was the Triumph brand that, by 1969, it’s said that 50% of all bikes sold in America over 500cc were Triumphs. Harley-Davidson was, of course, mightily unimpressed.
And now Triumph has brushed off the Speed Twin nameplate and bolted it onto the side of a thoroughly modern Bonneville.
It’s not the ground-breaker of the original and it’s not a rocket-ship by modern standards — but judging by the spec sheet (we won’t see the bikes until next year) it will be proper light and proper fast, at least within the genre of naked retro roadsters.
Highlights are the power (96hp compared with the regular T120 Bonneville’s 79hp) and weight (196kg compared with 224kg).
In short, the Speed Twin looks like a Bonneville that’s been put on a diet and then souped up to Thruxton R spec. In fact, it’s 10kg lighter than even the Thruxton so it should handle very well and be pretty darned quick too.
Here’s some of what Triumph has to say about the new bike:
A legend re-born
Changing the face of motorcycling, the original 1938 Triumph Speed Twin, with the world’s first successful parallel twin engine packaged into a game changing chassis, was a revelation to ride. Its smooth dynamic handling and superb responsive feel established Triumph as the number one motorcycle marque globally for performance and handling, setting the template for all that followed, and earning a global reputation for being the first real ‘riders bike’.
For 2019, the all-new 1200cc Speed Twin re-introduces this illustrious Triumph name to our Modern Classics line-up, setting all over again a new standard in class-leading handling, and delivering a new benchmark for how a modern custom roadster should ride and feel.
The brand new Speed Twin carries all of the contemporary custom style of the Street Twin but adds even more beautiful premium details. It delivers all the power, torque and technology of the Thruxton R, in an even more accessible modern set-up.
And, it offers all of the confidence inspiring ride and rider comfort of the Bonneville T120, but with even more engaged ergonomics.
The result, just like its iconic 20th century namesake, is a new performance icon that sets a whole new standard, with the chassis set-up, riding position, braking ability, suspension, and thrilling power delivery of a truly modern roadster.
Class leading handling
The all-new Speed Twin brings a new standard for class leading handling, with a precise, agile and dynamic modern roadster ride, and a confidence inspiring, intuitive feel.
The dedicated new frame developed from the Thruxton R delivers comfortable engaged roadster ergonomics, which combined with the high specification cartridge front forks and twin rear suspension units with adjustable spring pre-load, make for a truly unparalleled ride.
High specification twin Brembo 4-piston axial calipers on the front with twin discs, and a 2-piston floating caliper and single disc on the rear, provide excellent stopping power, complementing the motorcycle’s modern roadster character.
Adding to the confidence inspiring ride, the new Speed Twin also benefits from:
- 17 inch, lightweight 7 spoke cast aluminium wheels
- High specification Pirelli Rosso Corsa 3 tyres
- ABS and switchable traction control as standard
- Comfortable, upright, engaged riding position
- Tapered handlebars and new upper yoke and risers
- A comfortable new bench seat at a low height of 807mm,
making the bike accessible for all riders
- A significant 10 kilogram weight saving compared to the Thruxton,
contributing to its class leading handling.
The modern roadster character comes to life through its 1200cc High Power 8 valve, parallel twin Bonneville engine, specifically updated for the new Speed Twin.
This revised high performance engine features a low inertia crank and high compression head, and is developed from the Thruxton R’s powerplant.
Engine updates include:
- New magnesium cam cover
- Revised clutch assembly
- New mass optimised engine covers
Together these deliver a unique 2.5kg weight saving versus the Thruxton engine. With 97PS peak power @ 6,750rpm, the new Speed Twin achieves an impressive 76% increase over the 2016/17 Street Twin, and 49% more than the 2018 Street Twin.
Additionally the new Speed Twin engine also delivers a strong peak torque figure of 112 Nm @ 4,950rpm – an amazing 40% more than the 2018 Street Twin.
The Speed Twin’s all new distinctive twin upswept silencers, with satin black painted wrap and stainless steel end caps deliver the unmistakable sound of a British Twin, a unique exhaust note that matches its powerful and legendary character – rich, deep and full.
Behind the stylish exterior sits a liquid cooling system, carefully integrated to minimise its visual impact whilst achieving clean emissions and enhancing fuel efficiency. Combined with an extended first major service interval of 10,000 miles (16,000km), this contributes to a reduced overall cost of ownership.
Advanced rider technology
The new Speed Twin features a full suite of rider-focused technology to deliver advanced rider control and safety, plus enhanced rider confidence – sensitively integrated to maintain its iconic Bonneville style and character.
The Speed Twin’s technology features include:
Three riding modes Linked to the ride-by-wire system, the three selectable riding modes (Sport, Road and Rain), each with dedicated throttle maps and traction control settings, providing enhanced rider control and safety, and in ‘Sport’, a more immediate throttle response.
ABS The contemporary safety standard, with minimal visual impact, the ABS is responsive yet unobtrusive.
Switchable traction control Managing the Speed Twin’s high torque delivery when traction is compromised, the switchable system offers increased rider control.
LED DRL headlight Incorporated into the headlight, the LED daytime running light brings excellent visibility and a distinctive light profile (where legislation allows).
LED rear light & indicators Built into the classically inspired minimal tail set-up, the LED rear light and indicators bring a distinctive rear light pattern and excellent power efficiency.
Ride-by-wire Enhancing throttle responsiveness, safety and feel.
Torque assist clutch Optimised for a lighter touch and feel to the clutch to make it easier to ride, and ride longer.
Switchgear Elegant switchgear presents simple fingertip controls for easy access to the key features on the new twin clocks.
USB charging socket For maximum rider convenience, the USB charging socket charges riders’ essential devices.
Engine immobiliser Transponder integrated into the key adds greater security.
Stylish twin clocks New twin clocks, beautifully detailed and premium, incorporate a digital menu system accessed by the handlebar mounted scroll button.
