Thirty of the black bikes will fan out across the US during the rest of 2014 so the 111-year-old manufacturer of the world's most famous motorcycles can canvass public reaction to its most innovative product in years. The road show will extend into Canada and Europe in 2015 but, Levatich said, there were no immediate plans to put the Project LiveWire into production."We're interested in what people think, because we could take this in many directions," he said. "We're at the very cusp of an emerging industry and we're excited about it."Powering the Project LiveWire is a 74 horsepower engine that delivers 52 pound-feet of torque via a belt-driven transmission, giving a top speed of 92 miles per hour....AND THE REACTIONInitial reaction on social media reflected the passion of hard-core Harley-Davidson enthusiasts...Tyler Hutcherson of Springfield, Missouri, wrote on the company's Facebook page: "Congrats Harley-Davidson on taking a step away from fossil fuels and making a bad-ass looking bike in the process!"And on the same page from South Africa...
