Good Morning Don,
Good Morning Jake,
many thanks for your e-mail .Robert Leslie Graham was really something special .As Mr.Geoff Duke confirm ,in wet condition Les Graham was unbeatable .He won the Suisse Grand Prix at Berne in 1951 with a private Velocette 350cc .
Les started his motorcycle racing career in the thirties with speedway races :that's the reason of his ability .
Regards
Gerardo
