In 2024, we tested Triumph’s new Speed 400 and Scrambler 400 X powered by a single-cylinder engine and priced at $4,995 and $5,595 respectively, so the Triumph Speed Twin 900 is no longer the entry-level option in the Modern Classics lineup. For 2025, the Speed Twin 900 is updated with freshened styling, improved suspension and brakes, and more technology, providing a sophisticated step up from the 400s.
Styling updates include a more sculpted tank, chiseled side panels, and updated throttle-body covers. The muffler is now shorter, and the headlight unit is more compact. The bike gets a new aluminum flip-up filler cap and a simpler design for the footpegs.
Updates to the chassis start with the suspension. Replacing the previous conventional fork is a Marzocchi inverted fork, and in the rear are twin Marzocchi shocks with piggyback reservoirs. Adjustment is limited to rear preload, and rear wheel travel has been slightly reduced from 4.7 inches to 4.3 inches. Also new is a stiffer and lighter aluminum swingarm.
The Speed Twin 900’s brakes also get updated for 2025. The previous axial-mounted front caliper is replaced by a Triumph-branded 4-piston radial caliper pinching a 320mm disc. In the rear is a Nissin 2-piston floating caliper biting a 255mm disc. The bike is fitted with Michelin Road Classic tires on the 18-inch front and 17-inch rear cast-aluminum wheels.
The riding position has been updated with more available legroom, and the bench seat has a new shape to go with the narrower rear frame. Seat height is 30.7 inches, and an accessory low seat can lower the height to 29.9 inches.
Regarding the Speed Twin’s tech updates, the bike now includes lean-sensitive ABS and traction control. It comes with two riding modes: Road and Rain, with the latter providing softer throttle response. New instrumentation includes an LCD display to show speed, rpm, and gear, paired with an integrated TFT display for extra info like riding modes. A USB-C socket on the side of the instrumentation allows charging devices while riding.
The TFT screen is compatible with the accessory heated grips and the Bluetooth Connectivity module. Cruise control is also available as an accessory.

It comes with a slip/assist clutch and a 5-speed gearbox. The bike has a claimed wet weight of 476 lb and a fuel capacity of 3.17 gallons.
