Nicknamed “Moby Dick” by Motor Cycling magazine tester Dennis May, this SS100 is the original Speed Custom motorcycle. Purchased as a standard Brough Superior SS100 with special oversize cylinders from J.A. Prestwich (JAP) by Charles Hobb, the additional 13 horsepower proved to be not enough for the speed demon. Additional modifications, including an increase in compression ratio, higher-lift cams, lightened valves, and twin Amal carburettors, increased power output to over 65 horsepower – an increase of 21 horsepower over the standard engine. Moby Dick clocked in at 115 mph in top gear, though at that point it was the road that was running out, not the bike.

Sold in 1936 to the Bilbé brothers, who had immense success racing with the SS100, Moby Dick was traded again in 1940 and was subsequently kept hidden away during the war years. Resurfacing in North London, the Brough Superior was purchased by Tom Eccles, who owned the historic motorcycle for the next three decades. Restored in 1997 under the ownership of Roger Bilbé, son of one of the Bilbé brothers, Moby Dick was returned to its current condition. Since restoration, it has remained in the care of enthusiasts. Easily the crown jewel of any collection, a more unique and historic road bike would be hard to find.

• Motore da 1140 cc appositamente preparato da George Brough e da JAP

Soprannominata "Moby Dick" dal tester della rivista di motocicletta Dennis May, questa SS100 è la Speed Custom originale. Acquistata come normale Brough Superior SS100 con speciali cilindri maggiorati dalla J.A. Prestwich (JAP) di Charles Hobb, i 13 cavalli aggiuntivi non si sono dimostrati sufficienti per soddisfare il suo demone della velocità. Ulteriori modifiche, tra cui un aumento del rapporto di compressione, camme più verticali, valvole alleggerite e doppi carburatori Amal, hanno portato la potenza ad oltre 65 cavalli – con un aumento di 21 cavalli rispetto al motore standard. Moby Dick è così arrivata a toccare la velocità di velocità di 185 km/h, ma a quel punto la strada stava finendo, mentre la moto ne aveva ancora.

Venduta nel 1936 ai fratelli Bilbé, che hanno avuto un immenso successo in corsa con la SS100, Moby Dick è passata nuovamente di mano nel 1940 per essere poi tenuta nascosta durante gli anni della guerra. Ricomparsa nel nord di Londra, la Brough Superior è stata acquistata da Tom Eccles, che la terrà per i successivi tre decenni. Restaurata nel 1997, quando di proprietà di Roger Bilbé, figlio di uno dei fratelli Bilbé, Moby Dick è stata riportata al suo splendore attuale. Dal restauro, è rimasta sempre in mano, e curata, da degli appassionati. Sarà difficile trovare facilmente un gioiello della corona più importante di questo in qualsiasi collezione, una moto da corsa unica e storica.
