• 2012 Triumph Rocket III Roadster

There’s a reason why the Triumph Rocket III Roadster is considered the world’s largest mass-produced motorcycle. More than just its beyond reproach 2,294cc three-cylinder engine, the Rocket III Roadster is a machine that delivers a riding experience that’s virtually unmatched in any class.

The Rocket III Roadster takes on a streetfighter stance and delivers an attitude-laden ride that all motorcyclists should experience at least once in their motorcycle-riding exploits. The ergonomics alone ensure that the Roadster delivers a completely different riding experience from any other Rocket IIIs – one that is easier to hustle through the corners. The plush seating configuration allows both the rider and passenger to sit comfortably, whether for short-distance rides or long-haul escapades.

Up front, the Rocket III Roadster sports Triumph’s trademark twin headlights to make what already looks like an imposing motorcycle even more striking. The aggressive, stripped down look carefully balances the black and chrome detail while the comprehensive instrumentation – including fuel gauge, gear selection indicator and clock – creates an appearance that rocks in every sense of the word.

The Rocket III Roadster also comes with special color options. In addition to the popular metallic Phantom Black, it comes in two flamboyant color schemes: Phantom Red Haze and Phantom Blue Haze. These are hand-painted in Triumph’s Hinckley factory and contain high sparkle content which creates an impression of incredible depth in sunlight, transforming from near black to a vibrant red or blue.

And then there’s that powertrain. If it’s jaw-dropping enough that the Rocket III Roadster comes with such a whopping powertrain, the fact that it delivers 146 horsepower at 5,750 rpm and 163 lb/ft of torque at 2,750 rpm makes this Triumph monster a true bike that’s in a class all its own.

Total Motorcycle----“2.3 liters. 163ft.lbs of torque. Blacked out. Blinged up. Streetfighting cruiser. Hard. The Rocket III Roadster is not normal, it is very, very extraordinary. No other motorcycle on the planet comes close to delivering the tree-pulling levels of torque that comes as standard with the turbine-like triple. Twist and go. Sounds great, stops great. Standard ABS. Classic streetfighter looks”

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read full bio
