The Street Rod is a rare Harley, with its liquid-cooled engine.
When Harley-Davidson introduced the V-Rod family in 2001 for the 2002 model year, it signaled a new direction for the company. According to Harley-Davidson, the VRSCA V-Rod was “Harley-Davidson’s first motorcycle to combine fuel injection, overhead cams and liquid cooling.” In 2005, Harley-Davidson released the 2006 VRSCR Street Rod. The American Motorcyclist Association called the Street Rod, “a very un-Harley-like Harley.”
The V-Rod and the Street Rod share the same engine, called the Revolution, which was designed in partnership with Porsche. The Revolution was an 1130 cc liquid-cooled, fuel-injected DOHC with a 60-degree V-twin cylinder engine having four valves per cylinder.
Bore and stroke were 100 mm by 72 mm and the compression ratio was 11.3-to-1. According to “Motorcycle Cruiser” magazine, the Street Rod produced more horsepower than the V-Rod, “Not from any internal engine tweaks but from the Street Rod’s exhaust, which is less restrictive.” The Street Rod produced 120 horsepower at 8,250 rpm with a maximum torque of 80 foot-pounds at 7,000 rpm.
The Street Rod had a five-speed (one down, four up) transmission. A belt final drive system transferred power from the engine to the rear wheel. According to “Motorcycle Cruiser” magazine, the wet, multi-plate clutch “requires the stiff pull typical of Harleys … the gearbox is even smoother and lighter than the already good units in recent V-Rods.”
Brakes and Suspension
Harley-Davidson used Brembo brand brakes on the Street Rod, two 300 mm discs with four-caliper pistons in front and a single 300 mm disc with a four-caliper piston in the rear. The 43 mm inverted front fork, two rear shock absorbers and twin side swing arm provided the suspension. The front fork and shocks were adjustable.
The Street Rod was built around a steel frame. The handlebars on the Street Rod were adjustable and foot controls were mid mounted. The fuel tank was mounted under the flip-up seat, which makes it different from all other Harleys. Instrumentation on the cruiser included speedometer, odometer, tachometer, two tripmeters and a clock. There were indicator lights for turn signals, low fuel, low oil pressure, coolant temperature, high beam and neutral.
Dimensions and Colors
The 2006 Street Rod was 93.7 inches long with a wheelbase of 66.8 inches, which was .7 inches shorter than the wheelbase on the V-Rod. Ground clearance was 6.7 inches and seat height was 31 inches. The Street Rod had a dry weight of 618 pounds, weighing in at 655 pounds with all necessary fluids and a full tank of gas. The fuel capacity was five gallons. Harley-Davidson offered the 2006 Street Rod in vivid black, black cherry pearl, rich sunglo blue, yellow pearl, brandy wine sunglo and mirage orange pearl.
