Norton CS1
open-in-new
<p>The CS1 was a <a href="/facts/Norton_(motorcycle)/eWGtJ9l5">Norton</a> <a href="/facts/Motorcycle/owLPEqSr">motorcycle</a> between 1927 and 1939. Originally built as a <a href="/facts/Tt_racer/cI7ybh4H">TT racer</a>, and Norton's first design of an overhead cam engine, it proved successful as a <i>TT Replica</i> road bike. </p><p>After the early 1930s redesign of Norton's cammy models by Arthur Carroll, the CS1 became an upmarket road bike. The 500 cc CS1 and its smaller sibling 350 cc CJ1 continued on until the outbreak of WW2 in 1939. </p><p>Many later touring CS1 models were upgraded for racing, by adding and subtracting all the optional racing bits for Internationals. The Norton catalog had a long list of such parts available. The identifying feature of 1930s CS1 Models is the stub fitted carburettor - Inter models had a bolt-on TT carburettor. </p>
