Starting with a trio of prototypes American Kenny Dreer designed and built almost 10 years ago, Norton's Head of Design, Simon Skinner, first fit fuel injection, a catalyst exhaust and secondary air injection to achieve Euro3 compliance. He next made changes to reduce mechanical noise and vibration (both of which were issues on Dreer's machine), and re-engineered numerous components to be more appropriate for high-volume manufacturing. "Silly things like draft angles for castings, using metric tubing for the frame rather than inches-stuff like that," Skinner says. One thing that didn't change was the look of the bike. "Kenny got the styling 100 percent right," he declares.
