In 2023, Triumph rebranded the Street Twin as the Speed Twin 900. Aside from the name change, the model largely remained unchanged. That’s no longer the case, as Triumph makes good on the Speed Twin moniker with a handful of sporty upgrades.
Sum of its (new) parts
The new 900 holds on to much of its retro styling, but a nip here and a tuck there refresh the model for 2025. The side panels are streamlined, the engine cases are trimmed, and the bench seat is slimmer. Even the fuel tank is sleeker, contributing to the Speed Twin’s sportier look, overall. That seems to be a theme with the retro roadster.

Triumph tweaked numerous components when updating the Speed Twin 900’s look, going as far as to shorten the silencer and downsize the headlight bucket. Triumph photo.
The fork is now an inverted unit provided by Marzocchi. The Italian brand also supplies the piggyback rear shocks, which now connect to a “stiffer and lighter aluminum swingarm.” A larger 320 mm front brake rotor enhances stopping power (according to Triumph) while the model’s new wheels roll on Michelin Road Classic tires.

Triumph’s 900 cc Bonneville parallel twin remains at the core of the Speed Twin 900. Mechanically unchanged, the mill still puts out 64 horsepower at 7,500 rpm. Although, the real headline here is that peak torque — all 59 foot-pounds of it — arrives at just 3,800 rpm. Of course, the engine’s power delivery is determined by the Road and Rain ride modes.

If the Speed Twin isn’t “cool” enough in stock form, Triumph’s accessories catalog offers everything from waxed cotton panniers to bar-end mirrors. Triumph photo.
Technology was also a big point of emphasis for Triumph. The Speed Twin 900’s IMU-driven cornering ABS and lean-sensitive traction are prime examples. The LCD/TFT combo display is another upgrade. At least compared to the analog/LCD unit it replaces. A USB-C socket (side-mounted to the gauge) adds charging convenience for those running a bar-mounted device, while all-around LED lighting adds a modern touch to the classic design.

Aside from the nostalgic Pure White (with blue and orange tank stripes) paint option, Triumph also offers the Speed Twin 900 in Phantom Black (left) and Aluminum Silver (right). Triumph photo.
The 2025 Speed Twin 900 will start at $9,995, just $100 more than the outgoing model. Triumph estimates that the first units will land at U.S. dealerships in February 2025.

The Speed Twin’s 900 cc p-twin still mates to a five-speed transmission. Will that gearbox still hold up in the years to come? I’ll find out soon. Triumph photo.
Before those initial deliveries arrive, Common Tread will test the newest entry in the Modern Classics line by year’s end. If you have any questions about the renewed Speed Twin, leave them in the comments section. I’ll do my best to answer them in my upcoming first-ride review.
