Norton International Gallery
The Norton Inter story started as far
back as 1927, when Walter Moore (formerly the Douglas
chief designer) created the first Norton overhead
camshaft engine with bore and stroke dimensions of
79x100 mm, giving 490 cc capacity. Straight from the
drawing board it provided Alec Bennett with a TT victory
in 1927. Known as the CS 1 (Camshaft Senior one) it
was listed as a production machine for the 1928 season.
The smaller 348 cc version ( 71x85 mm) was known as
the CJ (Camshaft Junior). By 1930 Moore had left to
work for NSU in Germany and for the TT that year Arthur
Carroll , his successor at Bracebridge Street, redesigned
the camshaft engine. With this design Norton started
its incredible run of success in road racing. For
the 1932 season a sort of road going race replica
was listed as the International and was equipped with
TT Amal carburettor, racing magneto and close ratio
four speed gearbox. Later in the thirties the Inter
got hairpin valve springs and after the war Roadholder
telescopics and plunger rear suspension were added.
