And with this hard work arrived some positive numbers. Zero recently reported record growth for the first quarter of 2012, with sales up 178 percent over the same period of 2011, and revenue growth up 240 percent over Q1 in 2011.Karl Wharton (Chief Operating Officer, Zero Motorcycles) says: “We are now in full production and accelerated growth mode. Yet we are still a small company and therefore we understand that significant increases are relatively easier for us than for larger OEMs. However, on any scale, it’s an impressive performance, arguably making Zero Motorcycles the fastest growing and largest premium brand electric motorcycle manufacturer in the world.”Many factors can be attributed to the growth, including more efficient manufacturing, expanding dealer networks and media coverage. But the company says “without question at the heart of Zero’s success are the world’s longest range, mass produced 2012 Zero S and DS ZF9 models.”Zero says: “At 114 and 112 miles range respectively, both models received significant aesthetic and performance upgrades in 2012 and coupled with early availability, consumers are actually able to buy and ride them as well as all other Zero Motorcycles models today.”Zero Motorcycles, which are designed, developed and assembled 100-percent in the USA, is engaged in a strategic strategy for adding new dealers across North America and Europe in 2012.Scot Harden (Vice President of Marketing, Zero Motorcycles) says: “This comes down to the ongoing investment in product development, both in terms of design and performance. We are driven to be the market leader in innovation and technology. We listen to what our customers and prospective customers are telling us drive their interest to join the silent revolution.“These are motorcycles that protect the environment, are socially responsible in areas of noise restriction and support domestic energy sources and our need for independence from foreign oil. They reflect Zero Motorcycles’ desire to deliver fun, world-class, highly advanced expressions of motorcycle engineering design and art. The total cost of ownership, environmental and gasoline price issues help rationalize the buying decision, but make no mistake, our underlying goal is to deliver an expression of the enjoyment of motorcycling in its purest form.”Ride a Zero – Join the Silent Revolution (from a Zero Press Release)To widen its appeal, Zero is sponsoring a National Demo Day with its United States dealers on May 19, 2012. “Ride a Zero – Join the Silent Revolution” will enable riders to experience the pure joy of riding the only mass -produced 100-percent electric motorcycles currently in widespread circulation.Zero Motorcycles has a unique offering that appeal to both longtime enthusiasts and those new or returning to riding. Zero Motorcycles is proud of its cutting-edge technology but it understands technology is only a means to achieving performance and the “silence, smoothness and magical feeling” Zero Motorcycles riders experience, as one recent reviewer described it.As an example, if properly engineered electric powertrains do not require the clutch and gears necessary to make traditional gasoline motorcycle perform properly, why include them? In a recent consumer survey, fewer than four percent of respondents mentioned the presence of clutch and gears as a determining factor in their decision of buying an electric motorcycle. Zero Motorcycles strives for purity of enjoyment and a greater “magical feeling.” Noise, vibrations, smells and unnecessary components only stand in the way.For additional information, Follow Zero Motorcycles on Twitter @ZeroMC, become a fan of Zero Motorcycles on Facebook and check out what Zero is doing on YouTube at youtube.com/zeromotorcycles.
