Of course. Here is a full article about the 2007–2010 Harley-Davidson VRSC Revolution 1250 (V-Rod), written in the requested style and format.
The 2007–2010 Harley-Davidson VRSC Revolution 1250 (V-Rod) marks a pivotal chapter in the history of the V-Rod power cruiser, introducing a significant engine displacement increase and other performance refinements. Developed as a modern alternative to Harley-Davidson’s traditional air-cooled V-twins, the VRSC (V-Twin Racing Street Custom) platform was a collaboration with German automaker Porsche, resulting in the liquid-cooled, dual overhead camshaft “Revolution” engine. This period saw the V-Rod mature from its initial 1130 cc displacement into a more powerful and refined machine, solidifying its place as a unique “power cruiser” in the motorcycle market.
Development and Background
The V-Rod line was first introduced for the 2002 model year, representing a radical departure for the Milwaukee-based manufacturer. Its design was inspired by the VR-1000 superbike racing machine, and its core mission was to attract a new demographic of riders who desired modern performance and technology alongside the Harley-Davidson name. The centerpiece was the Revolution engine, a 60-degree V-twin featuring liquid cooling, fuel injection, and high-revving capabilities, all of which were uncommon for a production Harley-Davidson at the time.
The initial models were well-received for their straight-line acceleration and distinctive styling but faced some criticism for their limited fuel range and engine displacement that, while potent, left room for growth in the expanding power cruiser segment.
Key Upgrades in the 2007–2010 Harley-Davidson VRSC Revolution 1250 (V-Rod)
The most substantial change for the V-Rod platform came in the 2008 model year (with some changes appearing late in 2007 models). Harley-Davidson addressed rider feedback and market competition by overhauling the powertrain and braking systems.
Engine Displacement Increase: The original 1130 cc Revolution engine was bored out, increasing its displacement to 1247 cc (commercially referred to as 1250 cc). This enhancement boosted horsepower from approximately 115 hp to a more robust 122-125 hp, depending on the specific model and exhaust system. Torque also saw a significant increase from around 74 ft-lb to over 85 ft-lb, providing stronger acceleration across the powerband.
Slipper Clutch: To manage the increased power and improve rider experience during aggressive riding, a new slipper clutch was added. This performance-oriented feature helps prevent rear-wheel hop during rapid downshifts, making for a smoother and more controlled ride.
Braking System: The previous braking system was replaced with a high-performance setup from Brembo. This included dual-disc front brakes on most models, offering substantially improved stopping power and feel, a necessary upgrade to match the engine’s higher output. An anti-lock braking system (ABS) also became available as a factory-installed option, a first for the V-Rod family.
Increased Fuel Capacity: Responding to one of the most common complaints about the early models, the fuel tank, located under the seat, was enlarged from 3.7 gallons to 5.0 gallons. This extended the bike’s range, making it a more practical machine for longer rides.
Models and Variants (2007–2010)
During this period, the VRSC platform was offered in several distinct styles to appeal to different tastes within the power cruiser market.
VRSCAW V-Rod: The successor to the original VRSCA, this model featured the classic V-Rod styling with cast aluminum wheels and a pullback handlebar but was updated with the 1250 cc engine and a wider 240 mm rear tire.
VRSCDX Night Rod Special: Arguably the most popular variant, the Night Rod Special was defined by its “blacked-out” aesthetic. It featured a dark frame, engine, and exhaust, with minimal chrome. Its drag-style handlebars, forward controls, and slotted disc wheels created an aggressive, muscular stance.
VRSCF V-Rod Muscle:** Introduced for the 2009 model year, the Muscle brought a new level of street-rod styling to the platform. It was distinguished by its large, functional air scoops on the airbox cover, a chopped rear fender, integrated LED turn signals in the mirror stems, and a signature dual-exhaust system with satin chrome finishing.
These models shared the same powerful 1250 cc Revolution engine and frame but offered unique ergonomics and visual packages, allowing riders to choose the style that best suited their personality.
