Overview

What drove Triumph, at the turn of the 2000s, to persist with a three-cylinder when the entire industry swore by twins or inline-fours? The answer comes down to two words: character and torque. The Triumph 955i Speed Triple, introduced in 1999 and refined through 2005, embodies this philosophy with a delightful stubbornness. The 2004 model year represents the culmination of the 955 lineage, just before the 1050 took over. And frankly, this machine has nothing to be ashamed of compared to its successor.

Triumph 955i SPEED TRIPLE

The 955 cc three-cylinder produces 120 horsepower at 9100 rpm, which places it slightly behind a Suzuki GSX-S or a Kawasaki Z1000 of the same era on paper. But raw numbers tell little of what truly matters. The 96 Nm of torque available from just 5100 rpm changes everything. At mid-range, the Speed Triple pulls hard, with a smoothness and responsiveness that Japanese inline-fours struggle to replicate. This engine doesn't need to be thrashed to deliver pleasure. Simply roll on the throttle exiting a corner and you feel that linear, almost turbine-like surge that defines the sound and mechanical signature of the British triple. The six-speed gearbox does its job without particular brilliance, but with honest precision for the era.

On the chassis side, Triumph opted for a multi-tubular perimeter frame in aluminium that gives the package reassuring rigidity without falling into harshness. The 45 mm telehydraulic fork offers 120 mm of travel up front, while the single rear shock manages 140 mm at the back. Nothing revolutionary, but the whole setup is well calibrated for mixed use between road riding and sporty outings. The braking system, with its twin 320 mm discs gripped by four-piston calipers, proves both sharp and durable. The 212 kg wet weight remains contained for a roadster of this displacement, and the seat height of 815 mm makes the bike accessible to most rider builds. The 21-litre tank allows decent range, provided you don't wring the right grip too hard.

The Triumph 955i Speed Triple 2004 is aimed at a rider looking for something beyond the horsepower arms race. It's a machine for those who appreciate an expressive engine, an honest chassis, and a face like nothing else in a car park. The twin round headlights, that compact and aggressive silhouette, that wide handlebar inviting you to urban brawls or mountain passes stormed on a Sunday morning. Against a Ducati Monster S4R, it offers far less punishing maintenance costs. Against a Z1000, it counters with a meatier, less shrill temperament. It doesn't win every comparison test, but it leaves a lasting impression.

Today, finding a Triumph 955i Speed Triple on the used market is still a solid deal. Prices remain reasonable, well below the 11,500 euros asked when new, and the mechanicals prove robust provided the servicing has been kept up. The 2002 to 2005 model years are the most refined, with the 2004 offering the best balance between proven reliability and equipment. For a test ride of the Triumph 955i Speed Triple, you'd better plan a hefty rear tyre budget in 190/50-17, because this triple has a gift for devouring rubber with gusto. But that's surely a sign you're having fun on it. And that's really all anyone asks of it.
