In these days of extreme lean angles (see article below) we are used to riders scraping their knees on the track during cornering. BUT, back in the 1980’s this mad Frenchman, Jean-Phillipe Ruggia, who rode in the 250cc class, perfected a riding style that was so extreme that he regularly scraped his ELBOWS on the tarmac. Yes, seriously.
Note that, in the second picture, he is riding a 350 (different number plate colour – 250’s were green, 350’s were yellow and 500’s were white)
