 Despite overheating problems the Norton Kneeler with the nickname the ""Amm Sandwich"" or ""Silver-Fish"", Amm finished in 9th place in the 350 cc class that was eventually won by Bob McIntyre at an average race speed of 86.86 mph.Despite testing the Norton Kneeler for practice for the 1953 Isle of Man TT Races, Amm reverted to the non-streamlined Norton motorcycles due to handling problems with cross-winds on the Mountain Section of the course and also opposition by the TT Race Scrutineers.It proved a good choice as Amm won the 1953 Junior TT Race at an average race speed of 90.52 mph from Ken Kavanagh in 2nd place and Fergus Anderson in 3rd place.
