2024 Triumph Speed 400 and Scrambler 400X - First Look

New entry-level Singles developed with Bajaj Auto

Triumph announced two new entry-level modern classic models powered by a 398cc Single, the first products to come from its partnership with India’s Bajaj Auto. The Triumph Speed 400 and Scrambler 400X will first be available in India in July, and in all other markets by the start of 2024.

While pricing won’t be announced until closer to launch, on paper, the new 400 models offer a compelling package for the segment, with inverted forks, four-piston radial calipers, switchable traction control and a dual-channel ABS.

Both models are powered by the all-new TR-series engine. Named for the TR5 Trophy that Triumph raced at the 1948 International Six-Day Trial, the TR-series engine is a fuel-injected, liquid-cooled, 398cc Single with a four-valve DOHC cylinder head and a counter-rotating balancer shaft. Triumph claims a peak output of 39.5 hp at 8,000 rpm and 27.7 lb-ft. at 6,500 rpm.

The engine is styled after Triumph’s larger 900 and 1200 Twins, with black powder-coated engine casings, machined cooling fins and a triangular-shaped alternator cover. The cylinder head does tilt forward instead of straight up like a traditional British Twin, but from the right side, the TR engine certainly looks the part. The left side also resembles the larger models except it’s missing a second header pipe, though you’ll have to go to Triumph's website to know for sure, as Triumph did not provide any still photos of the left side of either bike.

Electronic aids common to both models include a Bosch ride-by-wire engine management system, switchable traction control and a Bosch dual-channel ABS (which can be deactivated on the Scrambler 400X for off-road use). A torque-assist clutch reduces lever effort and helps prevent the rear wheel from locking during downshifts. The lighting systems are all-LED, and both models come standard with a steering lock and anti-theft immobilizer.

The instrumentation combines an analog speedometer with an integrated LCD that shows engine speed, fuel level, and the selected gear. A USB-C port allows for convenient charging of handlebar-mounted devices such as smartphones or navigation systems. The 400 models are pre-enabled for optional heated grips.

Both models use a new hybrid spine and perimeter tubular steel frame with a bolt-on rear subframe. The Scrambler 400X’s fork is set further forward and it uses a longer chain, making for a longer wheelbase. Up front, Triumph installed a 43mm inverted Big Piston fork, while a single monoshock with external reservoir and adjustable preload sits at the rear. The Scrambler 400X’s suspension offers increased travel to better handle off-road terrain.

The fuel tanks hold 3.43 gallons, and while the fuel economy figures remain to be finalized, Triumph says it expects it to land somewhere around 80 mpg.

2024 Triumph Speed 400

The Speed 400 draws a lot of its styling from the Speed Twin 900 and 1200, with a bit of the more modern Trident 660 thrown in.

Metzeler supplies its Sportec M9RR tires, with a 110/70 R17 tire up front and a 150/60 R17 at the rear. The front wheel is equipped with a four-piston caliper and a 300 mm rotor. A 230 mm disc and a floating caliper for the rear brake.

The roadster offers a neutral riding position, with its aluminum tapered handlebar positioned slightly lower and further forward than on the Scrambler. The seat is 31.1 inches from the ground, and combined with the slender width, most riders should find it easy to put both feet flat on the ground.

Other features include a passenger grab rail, braided brake lines, and an upswept silencer running to the right of the rear wheel. Triumph claims a wet weight of 375 pounds.

The 2024 Triumph Speed 400 will come in three color options: Phantom Black, Carnival Red, and Caspian Blue.

2024 Triumph Scrambler 400X

The Scrambler 400X shares much with the Speed 400, but with a few changes to make it more suitable for light dual-sport use.

Visually, the Scrambler 400X draws inspiration from the Scrambler 900 and 1200, but the effect is somewhat ruined by the low mounted exhaust, with the twin-pipe silencer being an odd choice for a Single.

The suspension is tuned to better handle off-road riding and offers 5.9 inches of travel on the front and rear, both longer than on the Speed 400. Up front, the Scrambler 400X uses a 19-inch cast wheel, with a 100/90 R19 Metzeler Karoo Street tire. The rear wheel uses a 140/80 R17 tire. The front wheel is also equipped with a 320 mm disc (compared to the 300 mm disc on the Speed 400).

At 55.8 inches, the Scrambler’s wheelbase is 1.6 inches longer than the Speed 400. The saddle is taller, at 32.8 inches, and the flat high-grip footpegs are wider and positioned lower. Combined with the higher handlebars, the Scrambler 400X offers more natural ergonomics for a standing riding position. The 400X’s final drive gearing is optimized to provide what Triumph calls a "laid-back scrambler feel and response."

Other features include handguards and extra protection for the headlight, radiator, and sump, a handlebar brace with pad, and a longer front fender. Triumph claims a wet weight of 395 pounds.

The 2024 Triumph Scrambler 400X comes in three color combinations: Phantom Black and Silver Ice, Matt Khaki Green and Fusion White, and Carnival Red and Phantom Black.

    PLEASE... There seems to be no picture of the bike's left side. As a magazine type format with specs and pics, why would you let any company off the hook without a left side view? Is the left side finished in gypsum wallboard? Nice bike but still a bit heavy.

    By the way, my 1971 500cc BSA (mine bored to 600) single (Triumph had a similar bike) weighed in at about 320 pounds, fast and powerful fun with a kick start & compression release lever. Air cooled kept it lightweight but lighter still with the refrigerator sized muffler removed and a shorty attached. Oh what fun and can blow away anything in its weight/class range in 0-60 mph. Glad I kept it.

      Love that bike! Many of us remember the compression release too. I do like these new Triumphs. Some of my best riding memories were on smaller displacement bikes like 250 and 450 classes. My KZ250, 38,000 miles in 2 years, and my next bikes, the KZ440 twin. Light enough and super reliable. I have to mod various things like foot peg locations, rear brake lever and handlebars to accommodate my physical challenges; the KZ440 was easier than other bikes in that class to get those modifications done. Which is why I stuck with them, owning two more '440s for a total of 3 in succession. Some would say you can't ride long distances/tour on something like that, but I went all over the west and most of Canada on the 250 and 440s. This is my last KZ440, rescued from the original owners garage, laying on the floor on its side, buried under a pile of furniture. Very neglected, but only 700 miles! I spent 3 months repairing, restoring, finding good used parts, etc. I kept the previous bike as a parts donor. Here she is, first day out of my shop. There was a huge dent in the tank that I repaired myself. Engine/trans and related specs were like new, no abuse there. Love the older British bikes. My grandpa's friend had an Ariel Square 4, I was enamored by the looks and the sound of that strange looking engine when I was a little kid.

    That KZ440 is definitely a lot smoother than the 1971 BSA Victor, nice work. Funny you should also mention the left side BSA compression release. I thoughtfully (ha-ha) removed it after upping the compression ratio, adding an MX cam and resetting the timing. Kick starting the enlarged to 600cc single at over 12:1 compression ratio without precise crank position, could break a young mans ankle. The new electric start bikes are a very welcome introductory Triumph that should appeal to novice as well as seasoned pilots. They also captured a bit of the classic Brit single look. Now they need a way to strip it down 26+ pounds, rear sets, 150cc+ jug/piston kit and trick CMU for some off street fun.😱
