Single test: Triumph Rocket III Roadster

Triumph Rocket III Roadster in the test

Gigantic, powerful, strong as a bear

Maximum displacement on two wheels makes the Triumph Rocket III the boss in the ring. 2013 even more gigantic, because the roadster version now has no torque throttling in the lower three gears.

Maximum displacement on two wheels makes the Triumph Rocket III the boss in the ring.

Christian Vetter, test driver at MOTORRAD, smiles: “It’s fun!” For a Swabian engineer, it’s a real emotional outburst. He has just determined the impressive performance of the 2013 Triumph Rocket 3 Roadster. The 365-kilo colossus sprints from zero to 100 km / h in 3.5 seconds. And in the final fifth gear, the power cruiser goes from 60 to 140 in just 7.2 seconds. Respect! This is much faster than usual in this category and also a little better than before. For the roadster version of the three-cylinder, Triumph is now removing the electronic throttling in the first three gears. In third gear, the Rocket III lets loose more than 200 Newton meters on the dyno under 3000 tours. The result is impressive every time the traffic light starts: “First again!” – not exactly a compliment for a man, but a constant reality for a rocket man. The Big Block converts every twitch of the wrist into a powerful forward drive.

The chassis of the Triumph Rocket III Roadster


Fat: 368 kilos and a very black, nasty look.

The chassis springs and dampens very reasonably even on third-class, potholed roads. The 43 mm upside-down fork can do more and has more reserves than the stereo struts. The rocket is fed up, well tuned. Comfortable and bolt-stable even with the speedometer showing 200 and 5000 tours in the last gear. Pah, the Rocket eats Harleys for breakfast. Only deeply rolled longitudinal gullies take them off course. No wonder, with 240 mm rear roller and 150 mm front tire. After all, the raised Metzeler Marathon ME 880 stick well. The handling for such a colossus is great. The fat guy is really clever around the corners.

The crankshaft rotating transversely to the direction of travel has an effect. BMW boxers and Hondas send their regards to Pan European like Gold Wing. Even the lean angle is okay. Later on, the footpegs create furrows in the asphalt. Especially since the broad-shouldered and -legged, upright and casual sitting position gives you full control. You just have to be able to take decisive action. Class are gear indicators, 10,000 service intervals and cranked tire valves. A matter of taste the many black instead of shiny chrome components. But one thing is clear: Nobody offers more motorcycles for the money, 17,390 euros without additional costs, than the boss, the Rocket III Roadster.

The displacement monsters are a rarity.

With its 2300ccm engine, the Triumph Rocket III Roadster is a real displacement king on the used market.
