I was looking for details of the mighty KR211V, Kenny Roberts' Honda-V5 powered MotoGP bike for the 2006 season (bottom) when I spotted this Swiss rider, who came sixth in the 1951 Swiss GP. Made me smile, anyway. G
PS There is no Swiss GP any more due to the country banning virtually every form of motorsport after the Le Mans tragedy of 1955. Every day's a school day at the Sideburn blog.
KR Jr leads KR Sr, both riding KR211Vs. This is the bike with the British made chassis and HRC V5 that scored podiums (and should've won the Portuguese GP) in 2006. The last non-factory or non-satellite premier class GP bike to have any kind of success.
