Overview
It’s 2004, and Triumph, freshly risen from the ashes, seeks to seduce America without betraying its British soul. The Speedmaster of the time is a bit of this bold response: take the Bonneville base, inject a dose of custom style, but keeping a temperament that cracks a little more than the America. The result? A machine that plays on two fronts with more conviction than one might have thought.

Under the 16.6-liter tank, the 790 cc parallel-twin engine, offset at 270 degrees, is the soul of the beast. It delivers only 62 horsepower, a modest power today, but it is its early torque of 60 Nm at 3500 rpm that makes all the difference. It vibrates, it growls, it gives a lively sensation that today's more aseptic engines have sometimes lost. This engine, coupled with a five-speed gearbox with shortened ratios, gives this 245 kg custom surprising agility.
But where does this Triumph Speedmaster really stand? It makes a grand leap. On one side, the riding position, with its feet forward and its wide handlebar, shouts of leisurely cruising. On the other, the handling is frankly serious for a custom, and the front brakes with double discs inspire confidence. The Achilles' heel? The suspensions, especially at the rear, which tend to be dry and harshly remind you of the road's imperfections. The limited ground clearance also quickly tempers enthusiasm in corners. It's a sporty cruiser that invites you to play, but quickly brings you back in line.

Who rides this machine? For those seeking authentic custom style, without the bulk and lack of reactivity of large American displacement engines. It is an ideal gateway to the world of customs, easy to live with its low seat at 720 mm, but which offers more sensations than a simple wheelchair. Today, finding a Triumph Speedmaster used from this generation is a treasure hunt for lovers of modern classics. It also foreshadows the evolutions towards the 865, then the Speedmaster 900 and 1200 current models, more accomplished but also more aseptic.

In conclusion, this 2004 Speedmaster is not a perfect motorcycle. It is a compromise, sometimes rough, between relaxed aesthetics and a frustrated sporty temperament. But it is precisely this ambiguous character, this mechanical authenticity, that gives it its charm today. A Triumph Speedmaster test drive from this era will convince you that you can smile without needing 100 horsepower, simply with an engine that speaks and a style that doesn't go unnoticed. For a Triumph Speedmaster review, mine is clear: it is a historical machine, much more interesting and lively than its technical specifications suggest.
