The Norton Challenge P86, also known as the Norton Cosworth, is a racing motorcycle designed in 1973 by Keith Duckworth of Cosworth Engineering for Norton Motorcyles. The 750 cc (46 cu in) DOHC vertical twin was essentially two cylinders from Cosworth's world championship winning V8 DFV Formula One engine. A road going version was intended to be a replacement for the Norton Commando. Four complete machines[3] and around 30 engines[4] were made before the project was cancelled due to the financial collapse of NVT.
