New single-cylinder Speed 400 and Scrambler 400X set to join Triumph range in 2024

Triumph has ripped the covers off two new models that will be added to its modern classic lineup with the Speed 400 roadster and Scrambler 400 X taking pride of place alongside the Speed Twin 900 and 1200.

Designed from the ground up with a brand-new single-engine platform at their heart, according to Triumph the two new models are designed to deliver a fun, agile and confidence-inspiring ride for riders of all ages and experience levels

Conceived and designed in Hinckley, UK, the two new additions to the modern classics line feature an all-new fuel-injected and liquid-cooled 398cc single-cylinder engine punching out a respectable 29.4kW of power at 8,000rpm and 37.5 Nm of torque at 6,500rpm.

Technical highlights of the new donk include a four-valve, DOHC cylinder head and a crankshaft and finger-follower valvetrain with low reciprocating mass and DLC coatings that reduce friction contributing to what is claimed to be a free-revving yet tractable engine. Power is channelled to the back wheel via a six-speed gearbox with chain final drive.

The Speed 400 and Scrambler 400 X sport an accessible seat height of 790mm and 835mm respectively and a low weight of 170kg and 179kg.

Both models feature an all-new frame, with bolt-on rear subframe and cast-aluminium swingarm.

The Speed 400 features 43mm big-piston upside-down front forks, and mono-shock rear suspension, with an external reservoir.

Braking duties are handled by four-piston radial front brakes with a 300mm front disc and braided lines.

The Scrambler 400 X features a longer wheelbase, longer travel suspension, larger 19-inch front wheel rather the 17inch wheels on the Speed 400, and a wide handlebar for greater stability and control when riding on loose surfaces, as well as providing a more upright and commanding riding position. A larger cast steel brake pedal and high-grip foot pegs that are positioned lower and wider also make for a more natural standing riding position when riding off-road, while a larger 320mm front brake disc and optimised pad compound that provides more progressive braking performance in all conditions.

A Bosch engine management system offers a ride-by-wire throttle, switchable traction control, and dual-channel ABS with switchable ABS on the Scrambler 400 X.

The dual format instruments feature a large analogue speedometer and integrated LCD screen which includes a digital tachometer, a fuel range remaining and a gear position indicator. Both models also feature a USB-C charging socket

Both the Speed 400 and the Scrambler 400 X come equipped with a steering lock and an anti-theft immobiliser as standard, with a transponder chip integrated into the ignition key that ensures that only the owner will be riding away with a new Triumph.

The new single-cylinder machines have class-leading 16,000km service intervals, and a two-year unlimited mileage warranty.

The Speed 400 and Scrambler 400 X are expected to arrive on Australian showroom floors in December 2023 with pricing to be announced closer to the release date.
