If the rumors we are hearing are correct, Kawasaki may be the first to market with a super lightweight sportbike powered by a modern motocross single-cylinder engine displacing 250cc and/or 450cc. The four-stroke motocross era has fueled the development of high performance, single-cylinder engines that are logical candidates for street bike use. We are already beginning to see these engines utilized in street legal supermotard-style bikes. Sportbikes are next, and Kawasaki may be first.
