 NRV588 - The Norton NRV588 Rotary Racer  
This machine was prototyped in 2006 by Brian Crighton and is directly evolved from the racer he designed for the 1995 season. Featured in Motor Cycle News 10 March 1994, it was a projected onward development of the Duckhams Nortons which stormed UK circuits in 1994, when Ian Simpson won the British Supercup championship and team-mate Phil Borley was third.

Outstanding features of Crighton's latest racer are numerous computer-controlled functions and the retention of the 1994 twin-shock chassis layout, but with a single shock absorber on one side, taking advantage of the SPONDON swingarm's extreme rigidity. Many features on this machine are in common use on racetracks today, showing how far ahead of its time the NRV-588 was when first conceived more than 10 years ago.
