‘Born into a peerless bloodline’ say Triumph and Bajaj Auto, who have just announced the long-rumoured and spotted Triumph Speed 400 & Scrambler 400X motorcycles.

It’s brand new from the ground up, with the new 400cc liquid-cooled single-cylinder that’ll take the Speed and Scrambler design philosophy and apply it to a whole new generation and segment of rider for the British manufacturer.

Here’s all you need to know about the two new motorcycles from Triumph and Bajaj for 2024!

2024 Triumph Speed 400 and Scrambler 400 X

New 2024 Triumph Speed 400 and Scrambler 400 X Price and Availability

Update 05/10/23:Triumph has officially confirmed the pricing for both the Speed 400 and Scrambler 400 X in the UK - with the Speed 400 roadster given a £4,995 OTR price-tag, and the Scrambler 400 X at £5,595.

That's a seriously competitive price point for both models, particularly the Speed being available for under the £5,000 threshold.

Due for a 2024 worldwide launch, both bikes will be available in the UK, Europe, and Asian markets, and is the first bike to come from the two firms' 5-year collaboration project. Indian Triumph fans will be pleased to hear the bikes will be available as of July/August this year in India, though the final price there will not reflect the purchase price in other markets.

As of yet, Triumph has not disclosed the final price of the Speed 400 and Scrambler 400 X, though they did say it’ll be a ‘competitive price against premium brands’. One brand mentioned by name was BMW with the BMW G310R and G310GS, which are priced at £5,190 and £5,890 respectively.

The comparison to the BMW models is particularly interesting, as they are two variations on the same single-cylinder 313cc motor, producing 34 bhp and 28 Nm of torque – so with Triumph bettering this in the power department, we could potentially expect a price tag in the region of £6,000 – though the collaboration with Bajaj could mean it’s even cheaper than this. We’ll wait and see the final price in a month or two.

The new 400 duo will also naturally go up against bikes like the KTM Duke 390 and Honda CB300R for the attention of A2-compatible riders, and no doubt the upcoming Royal Enfield Himalayan 450 liquid-cooled update – which will be a fierce rival.

Colour options for the Speed 400 are Phantom Black, Carnival Red, and Caspian Blue. Whilst colours for the Scrambler are Phantom Black, Matt Khaki Green & Fusion White, and Carnival Red – the Green, in particular, looks stunning.

Naturally, give Lexham a try for a motorcycle insurance quote once these Triumph Speed 400 and Scrambler 400 X models hit the road.

Triumph Speed 400 and Scrambler 400 X Engine Spec

One of the main talking points for these two is the engine, one that is brand-new for Triumph, and with the expertise of Bajaj Auto, these motorcycles will be the first we see of the TR-Series motor - the question was asked if we can expect to see this motor in future models, but that was met with an expected 'no comment'.

Exceeding Euro 5 requirements, the same 398cc liquid-cooled single-cylinder motor features in both models with 4-valves and DOHC, quoted with an A2-friendly 39.5 bhp at 8000 rpm, and torque figures of 37.5 Nm @ 6500 rpm, and an electronic Bosch fuel injection system. Triumph tells us the delivery of this power is typically Triumph in its character, revving to a redline of 9500 rpm – therefore top speed could potentially be in excess of 90 mph.

It’ll have a ride-by-wire throttle, 6 gears, and a torque-assist clutch with slip-assist functionality. Plus switchable traction control, and switchable rear ABS for the Scrambler. It’s worth noting that in some Asian countries, as I’ve found out personally, 400cc is considered a big bike and anything over 80 mph is fairly unnecessary for the road.

Coming out of the factory with a 2-year, unlimited mileage warranty and 10,000-mile service intervals, the 400 duo will be built by Bajaj in India, with Triumph plants in Thailand & Brazil also involved.

Differences between the 2024 Triumph Speed 400 and Scrambler 400 X

Both bikes are built on the same framework, with a new ‘hybrid spine’ tubular steel with a bolt-on rear subframe and a twin-sided cast aluminium alloy swingarm at play.

This is where the differences between the two start to appear – the Speed with 17-inch wheels front and rear on Metzeler Sportec M9RR hoops, the Scrambler with a 19-inch front wheel and 17 rear on Metzeler Karoo Street hoops – a dual-purpose tyre with good on and off-road grip for hooning on light trails.

Most parts between the two variations of 400 are shared, though the Scrambler does head down a slightly different path for those who want that ability to do some off-road riding.

Both will feature big piston 43 mm USD forks, the scrambler with 10mm more wheel travel at 150mm, and the rear suspension is a gas monoshock RSU with external reservoir and pre-load adjustment, 150mm travel for the scrambler and 130mm for the Speed. The Scrambler will also have a wider bar, the width listed as 825mm to the Speed’s 795mm.

Braking power is ByBre, with a 300mm front disc with a 4-piston radial caliper on the Speed, and a bigger 320mm disc with a 4-piston caliper on the Scrambler. Both feature the same 230mm disc with floating caliper at the rear, though the ABS can be switched on the Scrambler – as well as switchable traction control for both.

So the Scrambler is slightly specced up here, suited for some rougher riding and jaunts off-road, and will as a result likely be a tad more expensive than the Speed.

Practical Riding Bits for A2 Riders

You’ll have a 13-litre fuel tank said to achieve around 80 MPG (to be confirmed), with wet weight for the Speed at a light 170 kg, and 179 kg for the Scrambler.

Due to the larger wheel and longer travel suspension, the seat height for the Scrambler is 835mm, and the Speed is 790 mm – the Scrambler being longer, wider, and taller, with a larger wheelbase and matched-up rake and trail to suit off-roading.

Finally, both models will have an analogue dial and LCD instrument panel, displaying the range remaining and your usual key bits of info like gear indicator, with a USB-C socket up front for your gadgets, plus a factory-fitted anti-theft immobiliser as standard.

As always with Triumph, there will be a huge catalogue of accessories for you to flick through, from styling to luggage.
