Yes Don, that is last year's TT and the rider is Masahito Watanabe (passenger Hideyuki Yoshida.) Their manager was Masato Kumano, who was a world championship contender 30 years ago.
At the newcomers day last year I was there with Jock Taylor's niece, Yvonne, and he spotted her and came over to talk about Jock.
I'd love to see more Japanese sidecar people across here... good practice for their own TT, too!
