2024 Triumph Scrambler 400 X Rounds Out Scrambler Line

The second model in Triumph’s new “TR Series” range of single-cylinder bikes might share a platform with the entry-level Speed 400 but it adds an on-point scrambler style that’s likely to make it the bigger seller of the pair.

Called the Scrambler 400 X, it shares the same all-new 398cc single-cylinder engine as well as borrowing the Speed 400′s 3.4-gallon tank and side panels, but it’s more than just a set of wheels and longer fork. Triumph has tweaked the frame design to suit the Scrambler, and changed the seat, bars, and pegs to give a distinct stance and riding position. The result is a bike that manages to carve a distinct niche as a retro-styled alternative to modern mini-adventure models like BMW’s G 310 GS and even KTM’s 390 Adventure.

Let’s start with what’s shared across the new TR-series range. The engine is a DOHC four-valve single with finger followers to reduce valve train inertia and a reverse-rotating balancer shaft to reduce vibrations. Kicking out 39.5 hp at 8,000 rpm and 27.7 lb.-ft. of torque at 6,500 rpm, it’s in the same state of tune as the Speed 400. Power is driven though the same assist-and-slipper clutch and six-speed box, but with a revised final drive ratio to suit the larger diameter of the higher-profile rear tire. As on the Speed 400, there’s switchable traction control and a long, 10,000-mile service interval.

Not that it’s a serious off-roader, but there are nods to dirt-road use, including more travel from the suspension. There’s 5.9 inches of stroke front and rear—increases of 0.4 inch and 0.8 inch, respectively, compared to the Speed 400. Triumph also fit the 400 X with different wheels (a half-inch narrower at each end) and with a 19-inch front instead of the roadster’s 17-incher. Slightly chunky tread means the Metzeler Karoo Street tires will cope with loose surfaces, but they’re named “Street” for a reason.
