The triumphant effort by Dungey capped off a historic evening for KTM, which enjoyed victories in both the 450SX Class and 250SX Class for the first time in history following Roczen’s dominant effort earlier in the night.

After JDR/J-Star KTM’s Joey Savagty claimed the holeshot and early lead in the 15-lap Western Regional 250SX Class Main Event, Roczen moved into the top spot before the completion of the opening lap. Once in control of first place, the German fended off some consistent pressure from Monster Energy/Pro Circuit/Kawasaki’s Martin Davalos to claim his fourth career win.

“I need to keep this up and take it to the next level,” said Roczen in his post-race interview. “This has been a great two races for me, but the season is not over yet, so I need to keep the pressure on as we head to San Diego next week.”

Davalos’ runner-up finish was the third of his career and his first this season. GEICO Honda’s Eli Tomac finished third and moved into second in the championship. Just one week after taking over the championship point lead, Roczen extended his advantage, which now sits at 20 points over Tomac.

One year ago, Dungey helped lead KTM to its first 450SX Class win in history and once again played a central role in the brand’s next landmark achievement in Monster Energy Supercross on Saturday night. As a result, he and Roczen bring considerable momentum into San Diego, which will serve as the final race on the west coast for eight weekends.

Qualcomm stadium will also be the final appearance of the Western Regional 250SX Class before its annual midseason break. The championship will resume for its seventh, eighth, and ninth races starting in Seattle on April 20.

At last season’s San Diego stop of Monster Energy Supercross, defending champion Ryan Villopoto and former champion Chad Reed provided one of the season’s most memorable battles. The pair traded positions on several occasions before Villopoto emerged with his third win of the year en route to the title. In the Western Regional 250SX Class, Dean Wilson took advantage of the misfortune experienced by then points leader Eli Tomac to win his second race of the championship and take over the points lead.

The first race held in San Diego was October 25, 1980, and Mike Bell won on a Yamaha. Reed has the most wins of any rider in San Diego, winning six races in 10 career starts. Jeremy McGrath, James Stewart, and Ryan Villopoto are the only riders to win at San Diego in both the 450SX Class and 250SX Class. A rider hasn’t won a 450SX Class race inside Qualcomm Stadium over consecutive years since Reed did it in 2007 and 2008. In the 250SX Class, it hasn’t been done since Stewart back in 2002 and 2003.
