Alabama-based Motus has been busy developing the first V4-powered American sport touring motorcycle. MST series motorcycles, including the MST-01 and premium MST-R, are new sport touring motorcycles engineered for rider and passenger comfort, extended motorcycle journeys, and responsive handling.
Motus Motorcycles worked with Katech Engines to develop the world's first liquid-cooled direct-injected V4 engine. Named the KMV4, the engine is an advanced, high performance powertrain designed specifically for Motus MST motorcycles, that is naturally aspirated with a turbo version to follow.
Now undergoing extensive durability testing, the KMV4 is also the first American V4 ever built for a production vehicle, actually a scaled down version of the Small Block Corvette Chevy V8, simply cut in half.
Motus partnered with Pratt & Miller Engineering, who has won numerous races in the American Le Mans, Rolex Grand-Am, NASCAR, 24 hours of Le Mans series, for development and manufacturing of their new motorcycle chassis.
Back in 2009, Brian Case, VP and Design Director of Motus Motorcycles said, "with their vast experience developing high performance, lightweight vehicles, we quickly identified Pratt & Miller as the perfect partner to engineer our lightweight, high-performance motorcycle."
The Motus MST series motorcycles incorporates many of Pratt & Miller's technologies such as a balanced and optimized 4130 chromoly space frame and lightweight carbon composite bodywork.
A combination of computer aided engineering tools such as CAD, finite element analysis, and multi-body simulation have been implemented throughout the motorcycle design process.
Motus intends to compete with European and Japanese motorcycle manufacturers currently dominating the popular sport touring segment. Sport tourers blend the two largest motorcycle segments, sport bikes and tourers, by combining comfort and performance.
Inc. Magazine named Motus a "breakout" company back in May of 2010. Click on this video to see and hear the latest of dyno test.

Motus has officially unveiled the company's first products at Pratt & Miller's Michigan facility. The venue was chosen because of Pratt & Miller's role in engineering the bike's frame. Not interesting enough for you? Eyeball the bike's heart, then: a V4, scale version of the pushrod V8 that powers the Corvette Racing C6.R.
Motus says that the engine is good for 160 horsepower and an unknown amount of torque, at least for the moment. That figure is good 20 horsepower more than what Motus originally anticipated out of the design, so a proportionate jump in twist isn't necessarily out of the question. Thanks to its design, the Motus V4 weighs just 130 pounds and measures 18 inches across at its widest point. We could think of all sorts of unseemly uses for such a contraption.
According to Hell for Leather, the MST-01 and MST-R are designed to be a counterpoint to the traditional American-designed motorcycle, offering plenty of comfort and a well-sorted suspension wrapped up in a 500-pound package. Head over to Hell for Leather for a closer look, as well as a video of the bikes' unveil.
