Grand Slams are relatively rare in baseball and are unprecedented in AMA roadracing. This year, in MotoAmerica’s Inaugural SeasonYamaha has done just that by standing on the top of the box in all four of MotoAmerica’s professional road racing classes: SuperbikeSuperstock 1000Supersport, and Superstock 600.

“Never before has a single motorcycle manufacturer won every Championship in all of the AMA/FIM-sanctioned professional road racing classes in one year,” commented Racing Division Manager Keith McCarty, “But, that’s what our Yamaha bLU cRU riders and teams did in MotoAmerica this year. We not only went four for four in Championships, but we also had a perfect season in race wins. Our riders won every race at every MotoAmerica round in 2015. No other manufacturer has ever done that before. It’s quite an accomplishment, and all of us at Yamaha are extremely proud, especially since we accomplished the feat during Yamaha’s 60th Anniversary as a company.”

How many races is that? Well, you’ll need the fingers and toes of more than three people to reach the 64 wins that the Yamaha bLU cRU riders notched during the MotoAmerica season. Here’s how the wins break down:
