• Constructed for the vendor by Dresda Autos
• AMA record in the 1,350cc Modified Vintage Class at 121.79mph (2008)
• Engine rebuilt by Mick Cook Racing
The exciting Norton-JAP 'special' offered here was built in its current form by renowned specialists Dresda Autos. Previously a retail outlet for scooters on Putney Bridge Road in Southwest London, Dresda Autos was owned by Dave Degens, one of the first special-builders to put the Featherbed-framed Triton into what might be termed 'limited production'. Degens later put his own Featherbed-derived frame into production, and there can be few companies on the planet with more experience of constructing these Norton-based specials.
The vendor bought the genuine Norton Manx 30M frame in 2006, the frame having originally formed part of a machine first registered in Portsmouth on 5th July 1957. We are advised that the machine is currently registered as a 1957 Norton-JAP. Dresda then modified the frame to accommodate a JAP MK 1,150cc engine that previously had powered a Cooper racing car.
The vendor then took the bike to the famous Bonneville Salt Flats in the USA in 2008 and broke the AMA speed record in the 1,350cc Modified Vintage Class at 121.79mph. He has since taken the Norton-JAP back to Bonneville on two more occasions, and has also proved just how tractable this machine is by using it as a fast road bike!
Since 2008, Dresda have modified the cylinder head, fitting lightened GS valves, while Mick Cook Racing have rebuilt the entire engine. The motor incorporates a Phoenix crankshaft and genuine JAP crankcases, which have been tested and are in excellent condition, while the twin BTH magnetos were rebuilt by Tony Cooper.
Presented in beautiful condition, this unique motorcycle comes with its original RF60 buff logbook (recording it as a Manx Norton); a current V5C Registration Certificate; copies of an AMA National Land Speed Record Certificate; and copies of Bonneville timing sheets.
'OBK 953' is registered as an Historic Vehicle and thus is MoT-exempt and qualifies for free road tax.
