Brno - A one minute silence was observed ahead of the Czech motorcycling Grand Prix on Sunday in memory of Angel Nieto the 13 time world champion killed last week in a quad bike accident in Ibiza.
Nieto was on a quad bike on Wednesday last week when he "had an accident with a tourism vehicle", police said at the time.
He was rushed to hospital in a serious state where he remained in intensive care, but his condition deteriorated before passing away.
Nieto sits second in the all-time list of most motorcycling world championship titles, two behind Italian great Giacomo Agostini.
Only Agostini and current Italy great Valentino Rossi have bettered his tally of 90 Grand Prix victories.
Nieto competed in his first Grand Prix at just 17 in 1964 before going on to win six world titles in the 50cc category and seven in the 125 division.
He retired aged 39 two years after his final world championship in 1986.
