The 1938 Isle of Man Tourist Trophy saw the Senior TT lap record of 90.27 mph set by Freddie Frith the previous year broken in 1938 when Harold Daniell completed a lap at 91.00 mph on his Norton, a record which would stand for 12 years.
Kluge was the second Lightweight TT winning non-British rider in a row, Omobono Tenni having won the previous year.
Between 1931 and 1937 Norton had six Senior-TT wins with the long-stroke CamShaft One (CS1) engine.
Norton entered the 1938 Senior TT with a new short-stroke engine, new telescopic front forks, and won for the 7th time, with rider Harold Daniell.
[2] Eric Oliver, who later won 4 sidecar World Championships, was entered this year, but retired his Norton from the Junior TT with a broken chain.
