2024 Triumph Scrambler 400X - Technical Review


Price: £5,595 | Power: 39.5bhp | Weight: 179kg | Overall BikeSocial Rating: TBA


Triumph’s Scrambler line-up is an enduring success for the British brand so it’s no surprise that a miniature version is among the launch line-up for its new 400cc single-cylinder model range. Stacking up against bikes from Royal Enfield’s Himalayan and Scram to KTM’s 390 Adventure and BMW’s G310GS the new Triumph Scrambler 400X looks immediately competitive.

Sitting on an all-new platform developed in partnership with India’s Bajaj, the first fruit of a long-standing relationship between the companies, the Scrambler 400X shares many parts with the new Street 400 roadster but has its own dedicated version of the new chassis as well as different suspension and equipment.

Despite being a result of Triumph’s Bajaj partnership, the Scrambler 400X will be built in Triumph’s factories in Thailand and Brazil as well as Bajaj’s Indian plants.

How much does the Triumph Scrambler 400 X cost? £5,595 on the road, although it won't reach UK dealers until late January 2024. What the price does do is undercut the BMW G310GS’s £5890 tag.

When it arrives, there will be three colour options: Phantom Black with a Silver Ice stripe on the tank, Matt Khaki Green with a Fusion White stripe, or Carnival Red with a Phantom Black stripe. All colours get rubber knee pads on the sides of the tank, which aren’t on the cheaper Speed 400 roadster even though the tank itself is the same 13-litre unit. Other extras over the Speed 400 include a sump guard, bolt-on handlebar brace, steel footpegs instead of alloy, a headlight grille, a steel radiator guard, a different, two-piece seat and hand guards as standard.

2024 TRIUMPH SCRAMBLER 400X Engine & Performance

The 398cc, DOHC, liquid-cooled single-cylinder engine is essentially the same one featured in the new Speed 400, with no change to its peak of 40PS (39.5hp) at 8000rpm or its 37.5Nm (27.7lb-ft) of torque at 6500rpm. However, the Scrambler gets a revised final drive ratio that, along with different tyre sizes, conspires to give it a distinct delivery compared to the roadster.

The Scrambler 400X also gets its own, dedicated exhaust end can, with twin exits, to set it aside from the Speed 400, but the main engine specs are unchanged. That means the same 89mm bore and 64mm stroke, the same 12:1 compression ratio and the same DOHC cylinder head with four valves operated by finger followers. A counter-rotating balance shaft helps tame the vibrations, and ride-by-wire allows the use of a switchable traction control system.

The lack of a high-level exhaust system, as used on the Scrambler 900 and Scrambler 1200 models, reflects the fact that the front section of the system, including the hidden front silencer, is shared with the Speed 400. It also helps keep the Scrambler narrower, so despite its taller seat it’s still easy to reach the ground.



2024 TRIUMPH SCRAMBLER 400X Handling, weight and suspension

Although the frame, which Triumph describes as a ‘hybrid’ is largely the same design as that of the Speed 400, the Scrambler 400X has a longer wheelbase thanks in part to different suspension but also to a 20mm extension built into the chassis itself near the steering head.

That head sits at a steep 23.2-degree angle, 1.4 degrees steeper than the Speed 400’s geometry, and holds longer USD forks, with the same 43mm diameter as the roadster but 10mm more travel at 150mm. Trail increases from 102mm to 108mm, and the overall wheelbase rises from the Speed 400’s 1377mm to 1418mm.

The rear monoshock is also longer, with 150mm of movement compared to 130mm on the Speed 400.

In line with its off-road style, the Scrambler 400X gets a larger, 19-inch front wheel instead of the 17-incher used on the Speed 400, with a slightly narrower, 100/90-19 tyre. The rear is also narrower, a 140/80, but remains 17 inches in diameter. Metzeler Karoo Street rubber is standard, giving a slightly deeper tread, but there’s no option for more aggressive wire wheels or truly knobbly tyres.

With various additional components compared to the Speed 400, the Scrambler is understandably a heavier bike. However, at 179kg wet it’s still no heavyweight

2024 TRIUMPH SCRAMBLER 400X Comfort & Economy

At 835mm, the seat is taller than the Speed 400’s 790mm and identical to the BMW G310GS’s height.

Adjustable bars, allied to lower, wider-set footpegs with removable rubber inserts, combine with the taller seat height to make the Scrambler 400X a more spacious bike than the Speed 400, while the two-piece seat and grab rail make it more suited to two-up riding as well.

As well as giving a more straight-legged riding position, the repositioned pegs are designed to work when you’re standing up as well as sitting down; even though the Scrambler 400X isn’t aimed at serious off-road riding, it should be at home on the occasional dirt road.

No official economy figures have been announced, but like the Speed 400 the Scrambler 400X should be good for around 80mpg, giving a range of more than 200 miles from the 13-litre tank.

2024 TRIUMPH SCRAMBLER 400X brakes

With a little more weight to stop, the Scrambler 400X gets a single 320mm front disc in place of the Speed 400’s 300mm version, but like its roadster sibling uses a four-piston, radial-mounted caliper. At the rear, there’s a single piston floating caliper on a 230mm disc, like the Speed 400.

Another difference is that the Scrambler 400X’s ABS can be switched off for off-road riding, disabling it on both the front and rear brakes.





BMW G 310 GS | Price: £5890

BMW’s reverse-cylinder, 313cc engine is, like the Triumph’s, a joint design with an Indian company, in this instance TVS. Giving away 85cc capacity, it has less power and torque, while the 175kg weight is 4 kilos lighter than the Scrambler 400X

Power/Torque: 34bhp/20.7lb-ft | Weight: 175kg (kerb)


KTM 390 Adventure | Price: £6299

Another bike built, like the Triumph, with the aid of Bajaj, the KTM 390 Adventure offers a fraction more power and an even smaller smidgen less torque than the Scrambler 400X. It’s a more off-road-oriented machine, though, and lacks the Triumph’s retro styling appeal. For that, the Husqvarna Svartpilen 401 – also made by Bajaj and based on the same engine and structure as the KTM – might be a closer option, and a cheaper one too at £5499.

Power/Torque: 43bhp/27.3lb-ft | Weight: 161kg (dry)


Royal Enfield Scram 411 | Price: £4599

In the Indian market – a huge one that Triumph hopes to crack with its new singles – the Royal Enfield Scram 411 is a key rival. It’s available here, too, and with a much lower price than the other rivals. Power is substantially lower as well, though. In 2024 a completely new Scram 450 is expected with a larger, water-cooled engine that’s sure to be a much tougher rival.

Power/Torque: 24bhp/23.6lb-ft | Weight: 185kg (kerb)

What is MCIA Secured?

MCIA Secured gives bike buyers the chance to see just how much work a manufacturer has put into making their new investment as resistant to theft as possible.

As we all know, the more security you use, the less chance there is of your bike being stolen. In fact, based on research by Bennetts, using a disc lock makes your machine three times less likely to be stolen, while heavy duty kit can make it less likely to be stolen than a car. For reviews of the best security products, click here.

MCIA Secured gives motorcycles a rating out of five stars (three stars for bikes of 125cc or less), based on the following being fitted to a new bike as standard:

  • A steering lock that meets the UNECE 62 standard
  • An ignition immobiliser system
  • A vehicle marking system
  • An alarm system
  • A vehicle tracking system with subscription

The higher the star rating, the better the security, so always ask your dealer what rating your bike has and compare it to other machines on your shortlist.
