Big updates for the retro roadster. The new engine is claimed to be marginally more powerful, cleaner running and, thanks to a new throttle, smoother too. Internal fiddles also means there’s a more even spread of torque, which should make it even easier to ride. New electronics include a quickshifter/ autoblipper and five-stage T/C.
