Who could emulate Rossi to become a Champion in their 30s?

In the 1950s, Libero Liberati, Geoff Duke and Leslie Graham were three pioneers to win titles in the 30s, while a little later down the line, 15-time World Champion Giacomo Agostini and seven-time World Champion Phil Read achieved the feat. Three more riders who possess 12 Championships between them have also continued to reach the peak of their powers in their 30s: Eddie Lawson, Wayne Rainey and Mick Doohan.
