Overview: This year’s motorcycle show at the NEC Birmingham is set against a continuing background of falling bike sales. William Woollard views the latest models the industry hopes will encourage people out of their cars and back onto two wheels. Frank Page investigates the revival of the Norton company and the new bike they’ll be launching on the private market this autumn, and Top Gear looks at some of the more radical machines on which hardened bikers keep the cult of biking alive. One of Top Gear’s family of test drivers joins Sue Baker to evaluate the new small Citroen, the AX, and compares it with its established rivals from Ford and Peugeot. And why are Britain’s motorways so frequently in need of repair? Chris Goffey reports on new ways to try to make them last longer.
