[1] In 1995 Walter Roehrich began construction of the 500 cc two stroke v-twin motorcycle, using Yamaha YZ250 engine parts on a prototype crankcase.

The 1130 was to be powered by a 180 hp supercharged Harley Davidson 1250 cc "Revolution" engine.

[2] It was the most powerful production motorcycle available in the United States, at 180 horsepower (130 kW).

Demand for a high-price limited production motorcycle dropped during the Great Recession.

[2] In 2009 Roehr produced a pair of electric sport bikes, based on a Hyosung GT250 chassis.

[2] Roehr wanted to build his own chassis, but adapting the Hyosung saved him $US15,000.
