New 2010 Roehr Motorcycle 1250sc Series

New 2010 Rhoer Motorcycle 1250sc
The heart and soul of a motorcycle is its engine. It determines the feeling and overall character of a motorcycle. Just as important as outright power is the way that power is delivered and the sound emitted from the exhaust, giving the motorcycle it's voice.

The New 2010 Roehr 1250sc is powered by a 180hp, specially developed version of the Harley-Davidson* V-Rod* engine. The engine was designed by Harley Davidson in cooperation with Porsche AG. It is loosely based on the Harley-Davidson VR1000 superbike engine. The design goal was to create a new engine that was modern, powerful and reliable providing HD with an engine for the future.
The result was an 1130cc (now available in 1250cc) liquid cooled, DOHC, eight valve, 60 degree, V-Twin engine with a performance like large bore short stroke architecture. This engine was named the "revolution" engine.

The Revolution engine debuted in the 2002 Harley-Davidson V-rod power cruiser and was widely praised for its excellent power, near perfect power delivery and soul stirring exhaust note.

It is only fitting that the Roehr 1250sc would take this great American power plant back to its roots and unleash it's racing bloodline in a new American superbike.

Roehr Motorcycles has applied its Roehr Supercharging System (RSS) technology to enhance this engine's power output without changing the character of it's power delivery, resulting in a truly thrilling riding experience. The result is the most powerful American production motorcycle engine available.
