Motus expanded to include dealerships in California, Nevada and Washington in May 2012.

Notable styling cues on the Motus are the exposed carbon fiber heads of the KMV4, as well as the slight forward sweep of the exhaust headers.

The Motus prototypes are targeted as sport-touring models, with integrated luggage from Givi another defining characteristic.

Engineering firm Pratt & Miller designed the transmission, and gets credit for the chassis and bodywork too.

The Motus frame is an eye-catching tubular steel design, as is the swingarm. Motus engineers incorporated the V-Four into the chassis as a stressed member.

Motus pitches its two prototypes, the MST and MST-R, as 2012 models with a production date of late 2011.

The KMV4 powerplant anchors the MST design, and represents the first American-built V-Four motorcycle.

The KMV4 features gasoline direct injection (GDI), which as the name implies injects fuel directly into the combustion chamber, instead of through the intake ports.

The longitudinal 90-degree V-Four on the Motus prototype is liquid-cooled and displaces 1645cc via 86.5mm bore and 70mm stroke.

Developed with Katech, a Michigan-based firm renowned for its V-8 engine development, the KMV4 lops the iconic American V-8 in half.

Four new Motus dealers have been announced on the West Coast.
