Norton 499cc Manx Replica

Frame no. none Engine no. none

Today the popularity of the Manx Norton in classic racing remains undiminished, with original examples racing alongside replicas of differing specification produced by specialist manufacturers worldwide. The superb Manx replica offered here was built a few years ago by an ex-racer with extensive in-period experience of competing on these machines. New parts were sourced from well-known specialists: the replica frame being supplied by Tony Dunnell, the crankcases by Andy Molnar, the clutch by Bob Newby, and the magnesium-cased six-speed gearbox by Mick Hemmings. Boasting over-square bore/stroke dimensions of 93x73.5mm, the engine incorporates a one-piece crankshaft (machined from an 80-ton forging), Cosworth shell bearings, an Omega forged piston, an original Norton cylinder head (modified), and titanium inlet and exhaust valves. Breathing via a new Mikuni VM 44mm carburettor and sparked by Interspan twin-plug ignition, the engine is estimated to produce around 56bhp, a considerable improvement over an original Manx. Other noteworthy features include 18" wheels and a Fontana front brake. Following completion, the machine was tested by the vendor at the 'Belgian Classic TT' at Geddine in 2015, successfully completing 44 laps. Offered with sundry invoices, this extremely well specified Manx replica is a potential race winner in the right hands. The owner is willing to answer and questions from prospective purchasers.
