Their MRX 650 is a sport bike built around a 90-degree V-twin engine and one-piece, twin spar, aluminum perimeter frame.

Alan Cathcart of Motorcyclist magazine in his 2006 test review, called the MRX, "the most important new American motorcycle in generations.

"[1] Company founder Daniel Fischer developed the company's first motorcycle for mass-production, the MRX 650 using suppliers including an EADS (Airbus) subsidiary for engineering, Harley-Davidson and Michael Jordan Motorsports contractor Gemini Technology Systems for frame development, and various companies related to US-based heavy equipment and automotive suppliers for other components.

[2] Rotax subsequently voided an agreement with Fischer in order to supply engines to Harley's Buell, with the Rotax 1000cc v-twin which had been used in Aprilia products and Fischer's first prototype ultimately supplied in a revised version for Buell 1125-series products.

As of April 2009[update], Fischer had begun shipping units, and in October 2009, they announced a production increase for the 2010 model year.
