The American rebellion in the form of a motorcycle is unfolding in Birmingham, Alabama. Confederate Motors set its sights on a 200-hp V-twin as the next evolution of the collectible Fighter series; and it has just delivered. Made exclusively from billet aluminum and featuring an advanced frame design that integrates both engine and transmission, the P51 Combat Fighter promises unheard-of performance from any motorcycle in its class.

Confederate Motors presented the original P120 Fighter in 2009, offering a limited production of an all-aluminum streetfighter motorcycle with a unique monocoque frame design and a huge V-twin that produced immense power. Six years later, the P51 Combat Fighter is the evolution of that model. It's the second generation, or G2, where a lot has changed except for the original concept.

The P51 is built around a monocoque structure made entirely of 6061-T6 aerospace-grade billet aluminum. This design binds the headstock, engine, fuel tank and transmission to a single unit that Confederate describes as "the stiffest, most fatigue-resistant and lightest chassis capable of housing the greatest amount of torque as a percentage of weight ever achieved in all of motordom." Big words; but with the T-Rex of an engine that sits in there, it should walk the talk.

The 57-degree V-twin has grown from 120 to 132 ci (1,966 to 2,163 cc) and the horsepower catapulted from 160 to 200 hp (119 to 149 kW). The torque output has made a huge leap forward as well, from 135 to 170 lb-ft (18.7 to 23.5 m kg). Amazing, unprecedented power from an air-cooled pushrod motor, channeled towards the rear wheel through Confederate’s brand new CX4 powertrain; a patented, drag racing-derived design.

This power hike was achieved through new cylinder heads, designed with an innovative air induction system. The strongest part of the frame, at the headstock area, incorporates an intake box that leads the air through a structural downdraft manifold – an industry first, according to Confederate. At its highest point, the air filter element is housed in a canister-shaped box with transparent sides. The same see-through design is used for the fuel tank, which is located under the seat and is embodied in the rear part of the central beam of the frame.

The front suspension is based on newly designed girder architecture with a fully adjustable shock absorber. In the rear, the layout is different compared to the P120, as the single shock is no longer centrally located, having moved to the left side of the brand-new swing arm.

Braking is handled by French specialist Beringer, which supplied the 4D Aerotek kit coupled with radial calipers.

Thankfully the seat has also grown, from the Walkman-sized cushion of the P120 to a saddle with a surface area approximately the size of an iPad mini. No doubt, an improvement.

Weight has been kept relatively low, at 500 lb (226.7 kg), thanks to the extensive use of light aluminum alloy in most parts, including the whole frame, engine cases and heads, girder fork and swingarm. Add a pair of super-light carbon wheels to come up with what promises to be an off-the-hook streetfighter, even more so than its predecessor.

Confederate will build 61 P51 Combat Fighters; 31 in the color of raw machined aluminum – dubbed "blonde" – and another 30 anodized in black. The price tag is set to US$113,900 for the blonde version and $119,500 for the black. If you reserve yours by September 7, Confederate offers a $10,000 discount.
