Yamaha ranks third among constructors in winning MotoGP season championships, and today Darren L. Jack showcases some of the race-worn memorabilia worn by the past three Yamaha factory race winners, including seven-time series champion Valentino Rossi, who won four titles for Yamaha. This Rossi helmet has been hand signed and is extremely rare because “The Doctor” has nearly every item he has worn in his personal collection. Check out this special item, along with other pieces from Yamaha champions, in this Hall of Fame Collection video.
