Josh Hayes turned 40 last week, but apparently age hasn’t slowed him down. Riding in a Texas rainstorm, the Monster Energy/Graves Yamaha rider showed he’s still the master of the class as he sloshed his way to a calculated victory over teammate Cameron Beaubier at the Circuit of The Americas in race one. Yoshimura Suzuki’s Roger Hayden ended up third.

Rain moved into Austin area just prior to the start of the Supersport final and it hung around until after the two MotoAmerica debut races were completed.

Hayes took off from the start for the 12-lap final and opened up a gap almost four seconds early in the race. Pole-sitter Beaubier chipped away at the lead and got it down to 2.5 seconds, but Hayes was able to maintain the gap and eventually stretched it back out to win by 5.279 seconds.

It was the 49th AMA Superbike win of Hayes’ career and the four-time AMA Superbike Champion dedicated his victory to his friend Dane Westby, a MotoAmerica racer who lost his life a few weeks ago in a street accident.

Fourth place in the Superbike race went to Bernat Martinez on a Yamaha YZF-R1 with Yoshimura Suzuki’s Jake Lewis rounding out the top five in his Superbike debut.

The Superstock class ran together with the Superbikes and it was RoadRace Factory’s Jake Gagne riding his Yamaha YZF-R1 to victory over the RSV4 of Aprilia HSBK Racing’s Dustin Dominguez. Tyler O’Hara rode the Tyler O’Hara Racing Yamaha R1 to third place.

The Supersport final was a wild race with several of the top racers crashing out in the difficult conditions. The man who stood on the top step of the podium when all was said and done was Yamalube/ Y.E.S./Graves Yamaha’s JD Beach, the Kentuckian taking his first-ever win in the premier 600cc class and his first win of any kind in five years.

Beach topped teammate Garrett Gerloff and M4 Suzuki/SportbikeTrackGear.com’s David Anthony.

Among the top men who crashed out of the race were race leaders Josh Herrin, on the Wheels in Motion/Motosport.com/Meen Yamaha, and Latus Motors Racing Triumph’s Bobby Fong. Both Herrin and Fong were able to remount, finishing seventh and ninth, respectively.

Beaubier turned the tables on his Monster Energy/Graves Yamaha teammate Hayes come Sunday, the 22-year-old Californian beating Hayes by 0.445 of a second in a thrilling race two of the MotoAmerica Superbike Championship of Texas.

Hayes, who won Saturday’s rain-sodden race one, pushed Beaubier for the full 12 laps with the battle coming down to the final corner. That’s when Hayes tried to put his Yamaha YZF-R1 where there simply wasn’t room.

Beaubier held his line as Hayes tried to stuff it up the inside, the pair coming together with Beaubier sprinting off to the checkered flag for his fourth career AMA Superbike win. Hayes, meanwhile, gathered himself up to still finish a close second. The pair now head to Road Atlanta with a win apiece and an identical points tally of 45 points.

For the second day in a row, Hayden finished third with the Suzuki rider much more competitive in the dry than he was in Saturday’s wet race. The Kentuckian led some laps early, despite getting his GSX-R1000 completely sideways through the esses on the opening lap.

Hayden eventually lost touch with the lead duo and fell into a battle with Gagne. Hayden prevailed for his second third-place finish in a row with Gagne holding on for fourth overall and a runaway victory in the Superstock 1000 class, which runs with the Superbikes but is scored separately.

Dominguez finished second in the Superstock 1000 class for the second time on the weekend, the Texan ending up 36.7 seconds behind Gagne on his RSV4. Taylor Knapp improved to finish third in today’s Superstock final on the FourFour Motorsports Yamaha YZF-R1.
