I came across this little tidbit on the Wikipedia Suzuki page.
"-Water-cooled 475 cc triples were built for racing purposes, producing 60 PS (44 kW) at 9,000 rpm. These took part in the JAF Grand Prix Formula Junior class as well as "MR" (Minicar Racing) meets. Thus equipped, the Can-Am style Fronte RF with Mitsuo Itoh at the helm took the victory at the 1970 "Junior Seven Challenge Cup" race, held at Fuji International Speedway, with an average speed of 130.9 km/h."
Can anybody verify this? Pictures, words, video, really anything would be appreciated, I'm really trying to piece together a definitive timeline of the JAF Grand Prix.
