Which 400 is right for you?

Four Triumphs share the same engine. They are not four versions of the same bike.

The Speed 400, Scrambler 400 X, Thruxton 400 and Tracker 400 all run Triumph's 398cc TR-series single. Same six-speed gearbox, same slip-and-assist clutch, same ride-by-wire throttle, same switchable traction control and ABS. Same 10,000-mile service intervals, same two-year unlimited-mileage warranty.

What changes is everything you actually touch: bar height, peg position, wheel sizes, suspension travel, tires, and on two of them the engine tune itself. Triumph built one platform and then built four genuinely different motorcycles on it.

That is why this range keeps pulling in riders who were not shopping Triumph before. Triumph says the 400s have brought more younger riders and more women into the brand than any model before them. We see the rest of it on the floor: people buying a first bike, people coming back after fifteen years off the seat, and people with a garage full of big bikes who want something light enough to ride on a Tuesday night.

None of these are training wheels. MCN rated the Speed 400 five out of five and called it a premium machine rather than a compromise. They are small motorcycles built to a real standard, which is a different thing entirely.

  1. 1Speed 400

    The one that does everything

    Best for
    The rider who wants one honest street bike. Commute on it, take the long way home, ride it on a Sunday. It asks nothing unusual of you.
    What makes it different
    It is the neutral one. Seventeen-inch wheels at both ends on road tires, the lowest seat of the four at 31.1 in, and 375 lb wet. Triumph describes the riding position as comfortable and neutral, and that is honest. Nothing about this bike is a statement.
    The numbers
    39.5 hp at 8,000 rpm and 27.7 lb-ft at 6,500 rpm. A 300mm front disc with a four-piston radial caliper. 5.5 in of front travel, 5.1 in rear.
    How it rides
    Upright, roomy, road-focused. Reviewers consistently rate it as a genuine first bike and an equally genuine second bike for experienced riders who want something light.
    Versions
    In the U.S. the Speed 400 comes one way. Color is the only choice.

  2. 2Scrambler 400 X

    The one that leaves the pavement

    Best for
    The rider whose regular route includes a fire road, a dirt driveway, or pavement that has given up. Also the rider who simply wants to sit taller and see further.
    What makes it different
    A 19-inch front wheel, 5.9 in of suspension travel at both ends, and a larger 320mm front disc with braided lines. Protection is standard rather than an accessory: sump guard, radiator guard, headlight grille, handguards and a handlebar brace. It is the only one of the four with a dedicated off-road ABS mode that switches off ABS at the rear wheel.
    The numbers
    The same 39.5 hp and 27.7 lb-ft tune as the Speed 400, in a longer 55.8 in wheelbase. 395 lb wet, 32.9 in seat.
    How it rides
    Triumph calls it more upright and commanding, and the extra travel is real. To set expectations honestly: it is composed on gravel and broken surfaces. It is a scrambler, not a dirt bike.
    Versions
    This one has a sibling. The Scrambler 400 XC takes the same bike and adds side-laced tubeless wire-spoked wheels, a high-level front mudguard, a flyscreen, an aluminum sump guard, engine bars and a two-piece seat. Ask us to have both side by side, so you can sit on them back to back and decide whether the XC's extra kit is worth it to you.

  3. 3Thruxton 400

    The one with a point of view

    Best for
    The rider who has always wanted the Thruxton silhouette and wants the riding position that goes with it, not a softened version of it.
    What makes it different
    Clip-on bars that sit 9.7 in lower and 1.6 in narrower than the Speed 400's, with the pegs 3.4 in further back and 1.1 in higher. A half fairing with a round LED headlight, bar-end mirrors, a bullet seat cowl and an upswept sports silencer. Pirelli Diablo Rosso IV tires.
    The numbers
    One of the two 400s with the uprated engine: 41.4 hp at 9,000 rpm, roughly five percent more peak power than the Speed 400 and Scrambler 400 X, from a revised camshaft profile and a higher rev limit. 27.7 lb-ft at 7,500 rpm. 388 lb wet, 31.3 in seat.
    How it rides
    Committed, and we would rather you hear that from us. Weight goes through your wrists in traffic. On a twisty road it makes complete sense. If your riding is mostly stop and go, look at the Speed 400 first.
    Versions
    No separate trims. Color is the only choice.

  4. 4Tracker 400

    The one that wants to be thrown around

    Best for
    The rider who wants attitude without commitment, and the easiest of the four to move around at low speed.
    What makes it different
    Flat-track styling that is structural to the bike rather than applied to it: the number board carrying 400, a tracker tank with knee cut-outs, a fly screen, a seat cowl, a twin-pipe silencer and dual-spoke wheels. Pirelli MT60 RS dual-purpose tires. 381 lb wet.
    The numbers
    The same uprated tune as the Thruxton 400: 41.4 hp at 9,000 rpm and 27.7 lb-ft at 7,500 rpm, with 80 percent of torque available from 3,000 rpm. Bars 0.9 in wider and 5.3 in lower than the Speed 400's, pegs 3.4 in back and 1.1 in higher. 31.7 in seat.
    How it rides
    Triumph's own description is elbows out, and it fits. Upright, wide, deliberately playful. The dual-purpose tires mean a dirt road is not off limits.
    Versions
    No separate trims. Color is the only choice. In the U.S. it arrives as a 2027 model.
