1924 is Norton's Year of Firsts. Alec Bennett wins the TT, using the new  ohv engine. "Pa" Norton fortunately lives to see the success, but dies on 21st April, 1925, aged 56. In winter 1926/27  Wally Moore designs the first Norton ohc engine, the "Cricket Bat", later taking it with him to NSU.

Moores ohc engine is fast but fragile. It gives Norton a TT victory in 1927, but its inherent weaknesses become obvious. After Moores departure to NSU, where he "designs" a carbon copy of the Norton CS1,  Arthur Carroll draws the legendary new OHC engine in 1929. This engine will give Norton an unequalled string of successes in the thirties and fifties. Only the Kompressor BMW, ridden by Schorsch Meier, can beat the Nortons at the 1939 TT due to its superior horsepower. With the ban of compressors in post-war racing things get back to how they should be!
