Triumph Expands Its 400cc Lineup With New Tracker and Thruxton

Triumph Motorcycles has reshaped its 400cc strategy with two new motorcycles that go far beyond cosmetic updates. The Tracker 400 and Thruxton 400 sit on a new chassis and use the latest evolution of Triumph’s 398cc TR-Series engine, giving the brand a much broader spread within the small-capacity middleweight space.

Both bikes use a revised liquid-cooled single that now produces 41.4hp at 9,000rpm and 37.6Nm at 7,500rpm. While peak torque remains unchanged from earlier 400cc models, it arrives later in the rev range, giving the engine a slightly sportier character. Triumph describes this as the most powerful version of the TR-Series to date, and it underpins both models despite their very different intentions.

Tracker 400

The Tracker 400 introduces a flat track-inspired design to Triumph’s lineup for the first time. Its riding position is upright and commanding, defined by wide, flat handlebars and rear-set footpegs. Compared to the Speed 400, the bars are wider and lower, while the pegs sit further back and higher, subtly changing weight distribution and rider posture. Suspension consists of 43mm USD big piston forks with 140mm of travel and a preload-adjustable rear monoshock offering 130mm.

Braking hardware includes a 300mm front disc with a four-piston radial caliper and a 230mm rear disc. Seat height is set at 805mm, and wet weight comes in at 173kg. Electronics are kept simple and approachable, with a torque-assist clutch, switchable traction control, and ABS. The instrument cluster blends an analogue speedometer with a digital tachometer, reinforcing the Tracker’s modern-classic positioning. Visual details like number boards, a seat cowl, upswept exhausts, and Pirelli MT60 RS tires complete the look.

Thruxton 400

The Thruxton 400 takes the same platform in a more performance-focused direction. Clip-on handlebars and rear-set footpegs place the rider in a noticeably more aggressive stance, with the bars sitting lower and narrower than those on the Speed 400. Suspension travel is slightly reduced at the front to 135mm, while rear travel remains at 130mm via a preload-adjustable monoshock.

Tire choice further separates the Thruxton from the Tracker, with Pirelli Diablo Rosso IV rubber emphasizing road grip and sharper responses. Wet weight rises slightly to 176kg, but seat height drops to 795mm, keeping the bike accessible despite its sportier ergonomics. A USB-C charging port is also fitted, matching the Tracker’s rider aids and instrumentation.

Together, the Tracker 400 and Thruxton 400 give Triumph four clearly differentiated motorcycles in the 400cc category. Rather than relying on styling alone, Triumph has used chassis geometry, ergonomics, suspension, and tire selection to define each model’s role, expanding the brand’s reach within one of the most competitive segments in the global motorcycle market.
