Cooper Webb Wins Indianapolis Supercross Round 9

Seth Hammaker becomes eighth 250 Class winner in nine rounds

Monster Energy Yamaha Star Racing’s Cooper Webb led all 25 laps of Round 9 of the Monster Energy Supercross series for his third win in the last four races and his sixth consecutive podium, all of which have been second or better. Webb built a solid lead in the first 12 laps and extended his advantage in the second half of the race after Chase Sexton tipped over in the sand while running second. Webb ultimately ended the race with an eight-second lead over teammate Justin Cooper.

The Indianapolis fans showed up once again for Supercross’ 18th visit to Lucas Oil Stadium. Indianapolis Colts Cornerback and Captain, Kenny Moore II, acted as the Grand Marshal for the race.

First place 450SX Class

“I was pissed off. I made a lot of mistakes today. Man, that was an awesome main event for me, probably one of the easier ones of my career. Got a good lead and could ride the pace. Obviously when Chase went down it really opened up the cushion. … I executed my start, rode great laps in the beginning and then put it on cruise control and (had a) drama-free race.” – Cooper Webb

Second place 450SX Class

“I’ve been fighting demons. I’ve been top-five the last four weekends, three of them being fourths, so it’s been tough to go home, regroup and go after that podium again. I’ve been sticking to it, trusting the process and really been riding good each weekend, consistent. … It’s cool for the team. One-two is big. This has been long overdue for me and I feel like I’ve been fighting for this for a while now.” – Justin Cooper

The 250 division featured the first of three East / West Showdowns in the 2025 season. Seth Hammaker earned the holeshot and led every lap to become the eighth winner in nine rounds of 250 competition. This was the second career victory of his career. Hammaker had pressure from fellow East Coast contender Tom Vialle in the closing laps but kept his composure to stretch his advantage to five seconds at the checkers. Haiden Deegan survived a trip through the safety netting to round out the podium.

First place 250SX Class

“Man, what an unreal feeling. My second win of my career and it’s been a while since I stood on the top of the podium, so that feels amazing. Got myself off to an excellent start. Tried to sprint away those first couple of laps. … When you’re out there in the lead and (have) a little bit of a gap, it was a little challenging to stay focused but I’m proud of myself, proud of the team, the group of people I have around me, my whole family.” – Seth Hammaker

Second place 250SX Class

“Slowly getting back in the rhythm and I felt great tonight. Like Daytona, I was again close to victory but Seth rode amazing. I’m pretty happy with second-place. The track was pretty tricky tonight, pretty easy to make a mistake.” – Tom Vialle

Third place 250SX Class

“I was upset. Obviously I wanted the win. … I ended up airing out that quad, or whatever you call it, and I ended up busting up something in my engine when I landed super hard so those last few laps, I tried to be smart and ride it in. My gears were clanging a little bit. No excuses. Those boys rode great: Tom and Seth were better guys tonight.” – Haiden Deegan
