It was a milestone moment for Rockstar Energy Husqvarna Factory Racing’s Zach Osborne as he crossed the line for his first 250SX Monster Energy AMA Supercross Championship victory inside Atlanta’s Georgia Dome.

In his 49th-career 250SX main event start, the former MX2 World Championship contender sped to his maiden victory in the East Coast 250SX category and took over the series lead from Joey Savatgy in the process.

“I had a great night,” said Osborne. “I worked hard for that win and I’m ready to keep the momentum going into next week. It feels good to have the red plate, I haven’t had red plates on my bike since 2012 in the British championship, so it’s going to be a big week and I’m super pumped with it.”

Recently joining Ryan Dungey, Marvin Musquin and teammate Jason Anderson under the wing of trainer Aldon Baker and now at the peak form of his career, the 27-year-old is admittedly lost for words.

“It’s unreal, I’m grateful to be in this position, to have this opportunity and to just be where I’m at,” Osborne added. “I can’t really put it into words, it’s just unreal.”

Osborne will now carry a slim two-point lead over Savatgy as the series makes its way to Canada for the first time in 2017 for round nine of the schedule in Toronto.
