The US Army Wants A Quiet Motorcycle,

one that when it runs on it's electrical power,

registers just 55 decibels, that's quieter than a normal conversation, it is also quiet in regular mode, when using diesel, gasoline, or jet fuel, scavenging fuel as need be on missions far from base it still only registers 75 decibels, which is slightly louder than the average vacuum cleaner, the bike is called the SilentHawk, work started on it last year, SilentHawk is based on Alta Motor’s RedShift MX bike, last year, Logos tested RedShift bikes with their new hybrid-electric engine, now, for Phase II of testing, Logos says they plan “to proceed with an aggressive Phase II program plan, with the goal of developing and testing the first operational prototype in only 18 months.” the bike also seems to have an invisibility mode as there are no pictures of it, the graphic at the top of the story is an artist concept of the SilentHawk Motorcycle With Saddlebags from Logos Technologies.
