British style cafe racer available to Americans in 1968 thanks to Sandy Kosman. The Street racer style didn't really take off in the States until the early to mid 1970's when some Triumph's were still used for the sport, but mostly Japanese fours.
Kosman made and distributed some very cool speed equipment during the '60s and '70s but just isn't a very well known name in the vintage speed equipment circles like Routt's, Webco etc. although he's still in business today making parts for modern motorcycle drag racing. Anyone have an old Kosman catalog they would sell me or let me borrow???
