This is the only dedicated book on OK Supreme motorcycles. The OK Supreme story is extraordinary and needs to be told. At well over 26,000 words, this book includes many previously unpublished diagrams, advertisements and historic photos. Includes a brief history of the marque (OK Supreme was one of Great Britain’s first motorcycle manufacturer) and an in-depth history of the Lighthouse and Silver Cloud with features on the people who worked for OK Supreme and why OK Supreme ceased manufacture in 1946. Included is a comprehensive Pilot/Silver Cloud engine analysis and workshop manual with notes on the changes in specification and instructional photos. This book is in soft cover format and measures 210mm wide (8”) and 297mm high (11”). Of all Great Britain’s ohc singles, the deep understanding of his primary market and desire to offer them sophisticated machines to meet their aspirations makes OK Supreme, under the control of one man, extraordinary and unique. This book is written for anybody who owns and wants to tune or rebuild their latter cammy engine. Easy step by step instructions. An absolute necessity for every Silver Cloud owner.
Brand new perfect condition WM1 40 hole 21″ valanced aluminium rim. I bought this from Italy and it is an unbranded 1950s style Borrani rim. In fact it is a Borrani rim without the branding. It is very light (1.65kg unpacked). With a little modification, I have fitted these to half width hubs, cotton reel hubs and full width 8″ Norton. It is beautifully made and very very light.
New replica of Lucas type “bug-eye” tail lamp bracket/license plate holder as used on many British motorcycles through the 30s and 40s. Photos with Miller Stop lamp (not included) to show fir. Will also fit most other British makes and will take Lucas lamps. Size of plate (minus tag at bottom) is 9″ wide, 6.5″ to bend and 3″ after bend. Made in 1.2mm thick mild steel, final bends to fit your machine precisely can be achieved easily using only a vice. It weighs 421g unpacked and unfortunately will NOT fit into an Australian 500g Postal Pack so I must use a 3kg Postal Pack

Extremely rare and desirable overhead cam OK Supreme “Lighthouse” engine dating from the early 1930s. When this engine first appeared at the 1930 TT, it was light years ahead of its competitors in specification and style. Features include short stroke (70mm x 64.5mm), narrow valve angles, barrel sunk deeply into crankcases and down draft inlet tract. The unique design of the cam arrangement is exclusive to OK Supreme. The cams are fitted to the vertical shaft and short horizontal pushers activate the rockers. Very few of these engines were ever manufactured and even fewer survive. perhaps only a couple of dozen at most. Production was discontinued at the end of 1933. This engine came from New Zealand where OK Supreme had considerable sales success. The crankcases appear to be for grass track racing which OK Supreme supported and was popular in New Zealand. Will need full restoration.

Eng No. D11M 18807. Frame No. 25449
Very rare and desirable genuine 1950 DOHC plunger 500 Manx. Has been slightly personalised over the years. Non-standard parts include early 30s Andre damper, 50s Manx clip-ons and BMW seat (fits perfectly) as well as an oil pressure gauge. Frame is perfect in every way with no cracks or repairs.
Original aluminium petrol and oil tanks. According to the dispatch records, this is first plunger Manx not to have Andre damper fitted as standard so owner has fitted early 30s Andre damper. Original magnesium cone hubs fitted as per 1950 Manx spec but 21 inch front and 19 inch rear rims (original would have had 20 inch rear rim but tyres this size almost impossible to source). New tyres. 2 way fork dampers as per 1950 spec Manx. Engine has been rebuilt by Melbourne-based specialist Manx engine builder Frank Rogers. Anything that needed replacing was replaced. Earlier crankcases fitted due to damaged originals (several decades ago). AJS vernier timing sprocket fitted to magneto for precise timing (Francis Beart used to do likewise). Current piston is low compression but higher compression piston comes with bike. Manx gear cluster. Later AMC type clutch (stronger spider). Correct BTH mag has been tested and throws excellent spark. Correct Amal RN racing carb. Correct tachometer. Tank has been professionally repaired ready to paint with no dings or dents.
This is an excellent example of a 1950 Manx lovingly pieced together and restored by well respected motorcyclist. It just needs your personal touches to finish.
SELLING PRICE $AUD40,000

This is the earliest of two surviving CCMCs. The other is a 1908 model. This is the first one ever built and has had only 3 owners. Shortly after the turn of the century, the Canada Cycle & Motor Company were determined to build a high-quality motorcycle using the most technically advanced components of the day.
Cycle parts including Chater Lea frame castings, high-tensile strength steel tubing and Birmingham hubs from Britain. French Traffault-style forks achieved a degree of good steering, fine road-holding and tolerable comfort and Bowden rim brake retarded progress at a pinch. Forward motion was provided by a Swiss Dufaux (Motosacoche) 288cc single cylinder engine, which featured side-by-side mechanically operated valves (most early engines had automatic inlet valves). A Longuemare spray carburettor made for easier starting and running than the popular but primitive surface carbs. A US-made trembler coil and spark plug brought it to life. It was a very advanced machine; probably the best in the world at the time.

One of a pair of genuine factory racers prepared by BSA race shop in 1957 for 1958 Singapore GP (the other was a 500). Other than meticulous assembly from selected parts, differentiating features from standard Gold Star include magnesium rockerbox and timing cover.
Bike is in largely unmolested condition. Paintwork and chrome reveals appropriate patina for a bike of this age kept in dry storage. There are signs that suggest some earlier detailing. Some bolts have chromed heads and spokes on rear wheel have been chromed and have surface rust. Chrome on tank is dull and there are signs of rusting on the bottom lip on one side. Clip-ons do not have welded-on perches so may not be original.
All mechanicals rebuilt recently at great expense. Has original racing Lucas magneto and GP1 carb although a concentric is fitted for ease of starting and around-town usage. Toolbox and oil tank is rounded type. Gearbox stamped RRT. Front brake is ribbed 8 inch. Rear brake ribbed. 19 inch Dunlop aluminium rims. Included in the sale is a brand new Evan Wilcox Lyta tank. Bike starts easily and is a pleasure to ride. Unmolested historic racing Gold Stars are like the proverbial hens teeth. It is probably the only genuine factory bike to survive in such original condition. Bike is in Perth, Australia. More photos available on request.
