After much waiting, Motus Motorcycles finally launched its MST sport-tourer to the public today. Unveiled at the Barber Vintage Motorsports Museum in Motus’s hometown of Birmingham, Alabama, the American motorcycle manufacturer will head to Florida for the Progressive International Motorcycle Show on Thursday, March 10th for a more public showing.

Developed in conjunction with Pratt & Miller Engineering, the Motus MST features the KMV4 motor, a 1,645cc V4 push-rod style engine that include gasoline direct-injection technology (GDI). Power for the Motus MST prototype is said to be 161hp @ 7,800 rpm; 122 lbs•ft of torque @ 4,500 rpm, while the bike tips the scales around around 500 lbs dry. Motus will be riding the MST around the United States to show off their work, meet with supporters, and look for dealers interested in carrying the line.







There might be snow on the ground for most of the United States, but things in the south are starting to heat up now that Motus has gotten its MST sport-tourer on the dyno, and for a quick ride in its latest video on YouTube. Letting the 1645cc gasoline direct-injection KMV4 motor “unleash the beast” as it were, the project seems to be coming together nicely as we’re given a rapid succession of quick-cuts on the MST’s build job.

We expect to see the built-in-America bike on city streets once the ice thaws (or Motus realizes it was 70°F in sunny San Francisco today, and makes a stop by the Golden State), and the video’s ending suggests we’ll get another installment while we wait for winter to subside.

We’re still going through the video to see if there’s any nuggets of info hidden inside. Call them out in the comments if you see something.













Motorcycle upstart Motus Motorcycles continues to press forward with its MST-01 sport-tourer, and has released a video that talks more about the development of their 1645cc gasoline direct-injection V4 motor: the KVM4. Balking at the advice of others not to build their own powerplant, Motus has teamed up with Katech to design an in-house motor for the Motus MST-01.
