1948 NORTON MANX BACKGROUND
The Norton Manx was developed in 1937, in both SOHC and DOHC form, to compete in and win the Isle of Man TT. Before fully developed, World War II intervened, and production of the Manx was delayed until 1946. The Manx quickly gained a reputation for its speed and reliability, allowing it to dominate the motorcycle Grand Prix racing and the Isle of Man TT for decades.
The Manx engine has an aluminum alloy cylinder block and head with a single overhead camshaft (SOHC) driven by a vertical shaft with bevel gears on both ends. They were hand-assembled engines that required skilled craftsman to complete. The 1948 Manx was the first to benefit from telescopic front forks and twin leading shoe (TLS) front brakes.
