Triumph has announced that two all-new models featuring a single-cylinder, 4-valve, liquid-cooled engine will join the company’s Modern Classics lineup for 2024. The 2024 Triumph Speed 400 joins the larger Speed Twin 900 and Speed Twin 1200, while the 2024 Triumph Scrambler 400 X takes its design cues from the Scrambler 900 and Scrambler 1200, with an off-road pedigree that goes back to the first factory scramblers of the 1950s.
Triumph says the new bikes are designed to deliver a “fun, agile, and confidence-inspiring ride for riders of all ages and experience levels.”
James Wood, Triumph’s global product marketing manager, said when unveiling the Speed 400 and Scrambler 400 X that the company’s ambition with creating the small-bore bikes was to give a “whole new generation of riders the opportunity to own a Triumph.”
“This means that the brief we stepped out to deliver on was all about creating a new 400cc capacity choice for our iconic Speed and Scrambler lineups,” he said. “These would, of course, need to be genuine Triumphs but even more accessible.”
The New TR-Series Engine
The new TR-Series engine is a fuel-injected, liquid-cooled 398cc single-cylinder engine making a claimed 39.5 hp at 8,000 rpm and 27.7 lb-ft of torque at 6,500 rpm and mated to a 6-speed gearbox, a slip/assist clutch, and chain final drive.
Wood said the “TR-Series” name was chosen to celebrate Triumph racing singles of the early 20th century: “Six Day Trial-winning machines that went on to inspire the TR-trophy racing bloodline of Singles and Twins that followed.”
Technical highlights include a 4-valve, DOHC cylinder head and a crankshaft that has been weighted and balanced to optimize inertia for low-speed rideability, as well as a finger-follower valvetrain with a low reciprocating mass and DLC coatings that reduce friction.
Triumph says the new engine delivers “responsive, fun, and characterful power delivery along with an evocative, rich, and distinctive exhaust note.”
2024 Triumph Speed 400 and Scrambler 400 X
Wood said a key part of the company’s planning with the new range was to “really understand what riders want and value in this world.”
“What riders have told us is that style matters a great deal to them, thereby it must be beautiful, but it also must be authentic,” he said. “They want something that’s very easy to maneuver, with a height that they feel comfortable on and in control of, and to have a ride that is unintimidating and fun but that also comes with a responsive, usable plan for power delivery, plus a great sound. On top of all that, they demand a very high level of quality and reliability, preferably from a brand with credibility and desirability, and of course, all for a price that represents genuine value for money.”
Beyond the new TR-Series engine, the Speed 400 and Scrambler 400 X share some of the latest rider-focused technology tailored to suit each model, including throttle-by-wire, switchable traction control, and Bosch dual-channel ABS, which can be deactivated on the Scrambler 400 X when riding off-road.
Dual format instruments feature a large analog speedometer and an integrated LCD screen that includes a digital tachometer, fuel range remaining, and a gear indicator. The display is also pre-enabled to show the status of accessory heated grips, if fitted, and there is a USB-C charging port.
Both the Triumph Speed 400 and Scrambler 400 X benefit from a slim standover with an accessible seat height of 31 inches on the Speed 400 and 32.9 inches on the Scrambler 400 X and low weights of 375 lb and 395 lb, respectively. Both models also have their own model-specific chassis, with a new frame, bolt-on rear subframe, and cast-aluminum swingarm paired with suspension set-ups tailored to each use.
The Speed 400 features a 43mm inverted fork offering 5.5 inches of travel, a monoshock rear suspension unit giving 5.1 inches of travel, lightweight 17-inch wheels, and roadster-specific geometry and wheelbase, all of which Triumph says offer “an engaging and intuitive ride along with a comfortable, neutral riding position that inspires confidence for riders of all sizes and skill levels.” Stopping power comes from a 4-piston radial front brake caliper with a 300mm front disc and braided lines and a floating caliper and 230mm disc in the rear.
The Scrambler 400 X features a longer wheelbase than the Speed 400 (55.8 inches vs. 54.2 inches), longer travel suspension (5.9 inches front and rear), and a larger 320mm front brake disc. A larger 19-inch front wheel and a wide handlebar provide greater stability and control when riding on loose surfaces. It also has a more upright riding position, and the larger cast steel brake pedal and high-grip footpegs are positioned lower and wider for a more natural standing riding position when riding off-road.
Triumph Design DNA with Contemporary Poise
Stuart Wood, Triumph’s chief engineer, said at the unveiling that it was more than just the specifications. “We’ve put our heart and soul into setting these bikes up to give you all the character and performance you expect from us,” he said. “So they’re really fun bikes, really great response, a little bit more power than the others as well. They really are fun to ride.”
However, Triumph says that both bikes are still “instantly recognizable.” Traditional touches, like the distinctive finned cylinder head and traditional exhaust header clamps, combine with contemporary details like the upswept silencer, graphics, and “sensitively incorporated technology,” such as concealed liquid-cooling and a flowing exhaust with a hidden primary silencer. They also feature the trademark black powder-coated engine casings, tough gold anodized forks, and high-quality paint and logo detailing.
The Scrambler 400 X’s all-road attitude is accentuated by protection for the headlight, radiator, and sump, as well as handguards, a handlebar brace with pad, and a longer front fender.
The 2024 Triumph Speed 400 will be offered with three two-tone paint schemes – Carnival Red, Caspian Blue, and Phantom Black – each featuring a prominent Triumph tank graphic.
The Scrambler 400 X is also available in three color schemes, each featuring Triumph’s distinctive Scrambler tank stripe and triangle badge: Matte Khaki Green and Fusion White, Carnival Red and Phantom Black, and Phantom Black and Silver Ice options.
While pricing has not yet been announced, Triumph says both the 2024 Triumph Speed 400 and Scrambler 400 X will be attractively priced versus the key competitors in each market.
James Wood said the bikes are the result of a “major five-year collaboration” with Bajaj Auto in India.
“Based on Triumph’s concept and design, Bajaj has worked hand-in-hand with our engineering team here in Italy to add that expertise in large-scale efficient and cost-effective manufacturing to our leading engineering and design capabilities.”
Wood added that the bikes will be built by Triumph factories in Thailand and Brazil, as well as Bajaj Auto in India, where both models will launch starting in July 2023. They will be on sale in all other markets in early 2024, when prices for these markets will be announced.
