1932 Vincent Hrd Model P.s

The P.S. or “Python Sport” refers to the most sporting of VINCENT in those very early years of the VINCENT company. The RUDGE motorcycle and wheel company needed business at this point owing to the Great Depression and found buyers among the many motor cycle builders of the day, VINCENT HRD among them. The engine is amazing. In 1932, RUDGE was producing a 4-valve engine of 500cc in this case with a most amazing way of opening valves using a very involved double rocker arm system. The variations were several with some having cylinder heads with fully radial valve locations, some with only the two exhaust ports being splayed (as on our P.S.) and so forth. Material as well varied with the most rare of the entire lot being the bronze head used on the ULSTER or tuned version. RUDGE men will tell you few bronze heads survive as most cracked due to casting flaws.
