Luxury automobiles have featured radar-based adaptive cruise control with emergency braking for several years, and the technology has found its way down market, trickling down to workaday cars, trucks, and SUVs in recent model years. Harley Davidson hopes to bring similarly advanced crash avoidance tech to their two-wheeled conveyances, if this patent filing is any indication.

There was once a time when Desmodromic valve technology was cutting edge and a necessary competitive advantage for Ducati in racing. The Desmo head doesn't use a valve spring to return the valve to the closed position, instead relying on a second valve rocker and a second lobe on the camshaft to pull the valve closed. In the early days of motorcycle racing, the metallurgy simply wasn't available to build the strong valve springs necessary to avoid valve float at the engine speeds Ducati wanted to build.
