The Harley-Davidson VRSC (V-Twin Racing Street Custom) is a model of cruiser motorcycles, produced by Harley-Davidson.The original VRSCA V-Rod had a 1,130 cubic centimetres (69 cu in) Revolution Engine, producing a claimed 115 horsepower (86 kW) at the crank. The V-Rod had 49 mm forks and a 180 mm rear tire, with solid disc wheels. The VRSCAs were all factory equipped with 3.7 US gallons (14 l; 3.1 imp gal) fuel tanks. In 2006 the VRSCA was equipped with Brembo Brakes. The VRSCA was only offered with forward controls. 2003 models were included in the 100th anniversary edition.
The Revolution engine is very similar in principle to the VR 1000 engine, using an intermediate shaft in the valley between the cylinders to drive the water pump and four cams via chains. In the V-Rod, those chains have hydraulic tensioners (as in a Boxster engine) instead of manual adjusters.
By stroking the crank to 2.83 inches and boring the cylinders to 3.94 inches, the engine's displacement was increased from 996cc to 1131cc.
The result is performance of a wholly contemporary kind. Although the exhaust note still reflects the slightly uneven firing order of a V-twin, even this is not similar to the company's air-cooled models. In another big departure from the usual Harley practice, the V-Rod has two tuned downdraft induction stacks between the vee, and these protrude upward into an airbox where one would normally find a fuel tank. Thus, the V-Rod has a dummy fuel tank, sans fuel-filler cap, and actually stores its fuel in a container beneath the seat. To fill up, you flip the seat on a hinge and then watch the reactions of people around you.
At more dignified speeds, the V-Rod steers easily and accurately, and its low center of gravity makes it tip effortlessly in response to slight pressure at the bars for predictable changes of direction. The upright riding position becomes tiring on long, fast trips, but the seat is pretty comfortable. Besides, there's a windscreen among the many accessories Harley offers in support of the V-Rod.
