As the championship race in both the 450 class and the 250SX East Region continue to get closer and closer, each round brings us more and more excitement. The St. Louis Supercross didn't buck this trend at all.

In the 250 class, we saw a race that came down to just .446 seconds between race winner Jordon Smith and second place Joey Savatgy. In the 450 class we saw Ryan Dungey slowly start to close in on Eli Tomac before Chad Reed held his line in front of Dungey for three and a half laps, which has added even more drama to the mix. 

Let’s dive into the lap data to figure out how these races were won and lost with this week’s Sign of the Lap Times. First, our traditional lap time charts.

450SX Top Three

Tomac wins another one to make it five in a row and these top-three lap time charts are starting to look the same. Once again, Tomac put that hammer down during the opening laps to give himself a comfortable cushion for when Dungey made his mid-race charge. 

Dungey found his pace quicker than he normally has this season and started to dig into that gap Tomac built during the opening laps, but ran into some issues mid-way through the race. More on this below. 

Marvin Musquin looked to be challenging Dungey early on in the race, but then settled into a pace that was just a tick off the leaders. During the post-race press conference Musquin said, "I was third and I was feeling really, really well. I was pushing. I was right behind Eli and Ryan, but it was tough to make a pass. I don’t know if I missed some energy or got tight a little bit. The track was tough. They started pulling away and then it’s tough. When you’re behind and you’re not close anymore then you kind of play it safe."
