Jay Leno really likes the Brough (pronounced bruff) Superior, a legendary British motorcycle built from 1919 to 1940. In fact, he likes them so much that he bought six: a 1929 SS100, a 1939 SS 100 (the most modern, and my favourite), a 1932 SS 80, two 1934 11-50s (they were police bikes), and a 1930 680.
Jay thinks the SS 100 is the greatest bike George Brough built. It has a Bonniksen Isochronous speedometer with a very accurate watch-type movement and a trip-distance display. The speedometer has two needles that take turns indicating the speed.
His 1939 Brough Superior SS 100 features a Matchless MX V-twin engine built specifically for this model. Catch his 1939 SS 100 in action…
