WHEN THE 1946 SUNBEAM S7 was unveiled to the post-war biking public, it was one of the most technically advanced motorcycles of its age. With its all-aluminium, "unit-construction", single overhead-camshaft, horizontally split engine, it also boasted shaft drive, a smooth power delivery and numerous other technical refinements that ensured it was going to be a massive hit.
