The Rocket III Classic exudes effortless, laid back cruiser style. Pulled back bars, footboards, large dual seat combined with classic styled reverse cone silencers and a two tone paint scheme could give the impression that it’s a little less purposeful than the standard Rocket III. Don’t be fooled.

The Rocket III Classic has all the performance, handling and usability that make every Rocket III so special.

Same engine, same torque, same awe inspiring performance, same effortless handling, same high spec sports bike derived brakes – all delivered with its own classic cruiser style.

Features & Benefits
Engine
The incredible 2.3 litre, in-line, water cooled, triple cylinder engine means that even two-up the Rocket III accelerates incredibly hard without obvious effort.

Despite its size, the engine is incredibly smooth as the balance, input and rear drive shaft contra-rotate against the crankshaft, which makes for minimal torque reaction.

Transmission
Shaft drive is ideally suited to dealing with such a strong production engine and gives the added benefit of being highly durable and virtually maintenance free.

Brakes
The Rocket III’s front brakes - twin four-piston calipers mated with 320mm floating discs – are built to sports bike specification and provide awesome stopping power. The rear brake, developed especially by Brembo, is a single twin piston caliper and 316mm disc.

Fuelling
Twin butterfly valves for each throttle body are used to give precise control over the engine and this set-up allows the ECU to vary the mixture flow and ignition map dependent on gear selected and road speed. The torque curve is thus tailored specifically for each gear ratio. And the result is impressive – over 90% of the engine’s prodigious torque output is available at just 2000rpm, giving incredible levels of flexibility and making the five-speed gearbox almost redundant.

Suspension
The Rocket III’s chassis is something quite special and centres on a large tubular steel twin-spine frame, which houses the motor, while 43mm upside down forks and spring preload adjustable twin rear shocks, built specifically for the Rocket III, add control, composure and supple compliance.

When Triumph launched the majestic Rocket III in 2004 it was to be the most spectacular flagship model since Honda's Gold Wing. The inevitable has happened and the Rocket III has evolved into a Classic version with a comfortable seat and big footboards. It still packs almost as much torque as two 999Rs, so don't let the cozy cruiser looks deceive you.

The Rocket III sounds quite boring and more like a car when on idle. Put it next to the mega twins from Kawasaki, Yamaha, Harley and Suzuki and you wouldn't raise an eyebrow from the sound. Despite the fact the Rocket develops 200Nm (147 footpounds) @ a ridiculously low 2,500rpm, it's when you really spin that huge 2.3 litre engine up that you start thinking about Nirvana. Three enormous pistons move up and down at breakneck speed and produce a sound unique in motorcycling. This is where the Rocket III becomes addictive. The monster torque curve just slings the 320 kilo machine forward, and when it starts revving with all that torque and 140bhp activated there is not a thing in the world that could stop it -- truly a rocket on two wheels. The momentum is unbelievable, and you start praising those very decent double four-pot front brakes mounted on an USD fork and the gigantic rear brake. A huge 240mm rear wheel takes care of all that power and torque and allows the Rocket to out drag any litre superbike up to at least 30-40mph. I could only imagine if this bike was chain driven with the opportunity to alter the gearing further…

That huge 2.3 litre engine is agricultural in size and is held in place by some serious frame tubes. On the move, the riding position is laid back, with a double touring seat and stretched handlebars. The powerful engine squirts the massive bike forward as if it was a 160 kilo sportsbike (did I say that already?). In the bends it is a different story, and the Classic features footboards that limit Ground Clearance even more than the standard Rocket III. You are not really bothered when riding the Rocket, as all that thrust is entertainment enough.

The brakes need to be really good as a stop-and-go style is what counts on the winding roads. So a bit of braking and acceleration is necessary to keep up with your mates where there are loads of tight bends. The solid upside-down fork allows heavy usage of the front brake alone, but for optimal deceleration it's always best to stomp the right foot down as well.

On the A roads and motorways the Rocket III Classic is an absolute delight. There is plenty of torque to pass cars and lorries on low revs and the directional stability is impressive. Like a bloody freight train as a matter of fact. The giant windscreen protects from the worst of the wind, but some buffeting from a little turbulence does happen at higher speeds.

The Rocket III Classic seems to have a limiter in top gear that stops acceleration above 130MPH. Not that it matters, as it is much more pleasant to cruise at legal speeds and ride the monster torque curve. Curious as I am, I always seem to try though.

Rocket III Classic comes as standard in a fairly basic form despite its touring emphasis. The only extras compared to the standard Rocket III are footboards, double touring seat and pull-back bars. Our test bike was fitted with about £1500 worth of extras ranging from the £350 windscreen to the £600+ leather panniers (I say + because you have to pay extra for the dresser rails and emblems). The panniers house 28 Litres
each and are fitted with a quick release system hidden under the leather straps. The sissy bar and luggage rack are also extra, but very handy if you carry a pillion. The Rocket III is perfect for pillions with the sissy bar, and with all that torque, you hardly notice the added weight of the pillion.

Few bikes get as much attention as the Rocket III. Particularly, the Classic as there are lashings of chromed parts everywhere. Not even pure muscle bikes come close to the mixture of power and cruising ability the Rocket III possesses. It can be whatever you want it to be in a straight line, but reminds you of its cruiser chassis in the bends. It is not bad in the bends, just heavy with limited Ground Clearance and a huge 240mm rear tyre. There are not many other bikes that can give owner satisfaction at this level. A true flagship model!
