Triumph Speed Twin 900 2025 — Specifications

Let's not confuse things: this Speed Twin is not the new 2025 model but the 2025 model year and color options of the previous version. Triumph regularly fields two versions of its models in a single year. To discover the modernized 900 Speed Twin, click here ->Motoplanete.com/triumph/nouvelle-900-Speed-Twin-2025.

What prevents us from delving back into this strategic model. The English brand has a strong interest in nurturing the most accessible of these Modern-classics, which ranks among its best-selling models. Hence the 2021 update, primarily focused on Euro5 compliance. Reduced emissions are a key attribute, without affecting engine performance, which was seriously revised in 2019.

This was also an opportunity to make a few small tweaks: open airbox panels, a small reinforcement for the headlight bracket, redesigned heel guards, new injection cover design, a 10 mm thicker seat with different foam, and new spoked wheels. A touch of makeup, in short, to prolong what it is: a small Bonneville with a light, playful, urban temperament.

The bike enjoys leisurely rides, having style on the streets or on national roads. But its twin-cylinder engine sometimes wanted to be more comfortable, more expansive when the rider's spirit opened to wandering. Certainly, the 1200 Bonneville has the grunt for that. Should the Speed Twin suffer for it for longer?

Not anymore. The parallel-twin engine has recently emancipated itself by showing a nice progression in power. Thanks to an increased compression ratio, a higher engine speed, a lighter crankshaft, fixed shafts, and crankshaft balance shafts, 10 horsepower were added to the existing 55. This represents an 18% increase over the first Street Twin – which had already gained 18% of torque from the 865 Bonneville. This comes at a price, which we will seek at high RPM. The English bike has more watts but its peak power and torque are higher in the rev range. The pulling force preserves its 8.2 kg-m, provided you seek it with 600 rpm more, at 3,800. We will provoke it a little more, with the satisfaction of a more pronounced surge and increased performance. Which opens up new horizons. Among the technical modifications, mention a clutch cover with mass optimization and a lighter clutch.

The Street Twin of old braked well, but no more. The caliper did the job in line with the machine's temperament. Now that it spits more at the connecting rod ends, an improvement in the braking system will not be a luxury. Triumph opts for a Brembo 4-piston caliper replacing the 2-piston Nissin, still on a 310 mm disc. Bite and effectiveness should step up a notch and provide a superior feel. The rear retains its 2-piston Nissin assembly with a 255 mm disc. No changes to the frame, shock absorbers, swingarm, or geometry. Just a tweak to the internal fork for a bit more effectiveness. The little Speed doesn't really seek to become a road weapon; just increase comfort.

Just to start, a good seat will be a good thing. With the extra cm of foam thickness, the riders should feel less of the dryness of our roads. We will then enjoy a natural, relaxed, casual riding position, designed to run at the pace of the twin's regular thump-thump. To the rhythms? The question can now be asked given the presence of the small Mode button on the left handlebar switch. What does it command? The Street Twin already had ABS, switchable traction control, ride-by-wire... What could it envy its big sister? The riding Modes. The engine's temperament can be tightened in 'Road' or relaxed in 'Rain', to carry gas under several facets. Each mode adapts the mapping and traction control settings.

Have we reworked the face for this evolution? Mmmhmm... No need. We will just tweak a few small things. A slightly more classy brake fluid reservoir, a new seat cover, a perforated protection plate from the ex-Street Cup over the left engine cover, airbox panels very slightly redesigned, a speedometer subtly revised, and new more refined spoked wheels with machined flanges. You will need a very discerning eye to spot the changes on the headlight brackets and the tank badge.

Rear LED lights, a USB socket, and coded immobilizer are still standard. The options corner is enriched by the tire pressure monitoring system TPMS, alongside the 120 accessories planned to customize this Speed Twin 900. Also available in A2 configuration, this motorcycle skillfully maintains the discovery of the English Classic. However, the price is not so democratic.
