The Track

In the days leading into race day there was plenty of talk regarding the weather, and whether or not we’d have a mudder in San Francisco. Well, we’re past the point of conjecture—we’re in for a mudder. Even if it doesn’t rain any more today, which it will, the guys are still facing one seriously mushy racing soft and wet racing surface. The track crew kept the track covered with plastic until about 11 this morning, so the jumps aren’t completely soaked, but the low points between jumps all have standing water. The start stretch is especially drenched, and the mud was so thick at one point, a four-wheel-drive side-by-side got momentarily stuck, requiring track workers to manually push it to get it going again. The mud is that thick, heavy type. The kind that if your boot sinks a little too low, you’re probably going to pull your foot out of itwhen you try to take your next step forward

It's not all bad news though. As mentioned, the track was covered earlier, so the jumps themselves, in their current form, aren’t total mush. Slick? Yes. Falling apart? Not yet. The whoop seciont isn’t too bad either, although they’ll probably deteriorate as soon as practice gets underway. It’s too bad we’re looking at a wet track, because today’s track layout looks awesome, especially the rhythm lanes. One of them looks like it would present multiple lines, and the other one, which immediately follows the first after a small lefthander, is long and bends gently left and ends in a nice big bowl turn. Hopefully the rain doesn’t completely dump, and we’re able to see the guys race the track somewhat, instead of attempting simply to survive the mud.

First Qualifying Sessions

250SX

With the updated schedule and no free practice, these times do count for overall qualifying. The first session—the 250SX group B qualifying session—a handful of riders went down navigating he slippery, muddy, and puddled up course.

When the checkered flag waived, it was Maxwell Sanford with a 1:06.236 topping the session. 

The 250SX group A session took to the track and again, we saw a handful of riders go down. Championship leader RJ Hampshire had a few spills, as did Robbie Wageman, Max Miller, Anthony Bourdon, and more. Nate Thrasher topped the session with a 1:05.888, as Hampshire finished P2 with a 1:06.054.

Update: Thrasher's time was taken away as the AMA noted: "(57) - Fast Lap Invalidated." Hampshire now claims the top spot.

450SX

In the 450SX group A first qualifying session, again a lot of riders going down around the track. Malcolm Stewart had a big get-off in the first rhythm section late in the session, and good-guy Adam Cianciarulo stopped on the jump ahead of Mookie and helped direct traffic around the downed #27 and his Husqvarna FC 450. When the checkered flag waived, it was Aaron Plessinger, who put down a 1:09.128 to claim P1 in the session.

This track is rather difficult to put together with the mud as there is a lot of doubling and rolling. Riders are mostly doubling the standard supercross triples, although there are a few riders still hitting all three. Same goes for the finish line double, as there are a lot of riders rolling it, but some are hitting the full jump.

Benny Bloss topped the first 450SX group B qualifying session with a 1:20.285.

Justin Rodbell topped the first 450SX group C qualifying session with a 1:23.665.

Update on Second Qualifying Sessions

2:30 p.m. local time

The American Motorcyclist Association's Director of Racing Mike Pelletier came on the Race Day Live broadcast to inform everyone at the stadium that the second qualifying sessions would be canceled. The Dirt Wurx crew had equipment on the track as they were fixing and adjusting the track slightly. With the conditions, a few changes were made, including the supercross triple after the finish line jump. The standard supercross triple was changed to a mellow double. The finish line jump also had some dirt taken off the top and it was mellowed down as well.

250SX – Heat One

When the 250s blasted out of the gate and into the mud, it was Jordon Smith coming into turn one first, but Jo Shimoda snuck in and stole the spot at the last second. Mitchell Oldenburg held third, with Garrett Marchbanks and Anthony Bourdon rounding out the top five. A few laps in and Shimoda made a mistake and nearly went down. Smith was almost in a position to make a move, but Shimoda shut the door. In the ensuing whoops section Shimoda swapped and nearly went down several times, yet somehow held onto the bucking bronco beneath him. It was a work of sloppy, muddy, and comical art. Smith wasn’t so lucky and went down in the whoops. Not to worry for Smith, though, who was able to climb back to second within a couple laps. When the checkers flew it was Shimoda taking the win by nearly twenty seconds over Smith. Marchbanks, Oldenburg, Bourdon, Julien Beaumer, Josh Varize, Slade Varola, and Geran Stapleton filled out the remaining transfer spots.

The amount of chaos in this race cannot be overstated. Everywhere you looked guys were going down, going off the track, and slipping every which way. There were too many crashes to keep track of, and that was just the first race. The track is only going to get more chewed up from here!

250SX – Heat Two

When the gates dropped on the second heat, it was Kawasaki's Levi Kitchen and Maximus Vohland out front early on, but it was GasGas rider Ryder DiFrancesco who jumped ahead of the green duo to move into first place! DiFrancesco settled into first as Kitchen and Vohland battled. RJ Hampshire made his way into second in typical RJ fashion, pushing the limits. He stayed up though! Lots of carnage on this heat race just as the first one. Nate Thrasher, who qualified well, had a tough start to his night. Carson Mumford rode in a fifth-place finish ahead of Matti Jorgenson, Phil Nicoletti, Cole Thompson, and Hunter Yoder. Yoder made it in, but he was slipping around, doing a full 360 in the turn at home plate on one lap! Thrasher came through in tenth in the first non-transfer spot. Tre Fierro went down on the finish line jump, but luckily, he did not get ran into. Robert Hailey, who is about 6'6" I believe, went down and had to have three flaggers help him get his bike off the track. Looked like his Yamaha YZ250F had seized up, ending his lap early.

450SX – Heat One

Jett Lawrence looked like he was going to nail the holeshot in this one, but he overcooked it and came in too hot, losing several spots. The man who executed perfectly was Jorge Prado, and in the blink of an eye, the Spaniard had somehow created a sizable lead over Chase Sexton in second place. Behind Sexton was Lawrence, but there was about eight seconds between them. Then, a few laps in, Lawrence went down in the whoops and dropped a spot to Ken Roczen. Next thing Lawrence knew, he had Eli Tomac all over him. The two proceeded to yo-yo back and forth for several laps until Lawrence went down again, handing Tomac the spot.

Up front the battle for the lead was starting to heat up, as Sexton had reeled in Prado. Just when Sexton got on Prado’s rear fender, he bobbled, giving Prado some breathing room. This process repeated several times, and Prado was able to hang onto the lead to take the win.

Sexton took second, with Roczen, Tomac, Lawrence, Adam Cianciarulo, Shane McElrath, Justin Rodbell, and Vince Friese all transferring to the main. Dean Wilson and Friese had quite the battle on the final lap, but Wilson was never quite able to throw it in on Friese.

Update: Friese was penalized three spots for cutting the track, putting him in twelfth in this race.

450SX – Heat Two

The gates dropped on the second heat race of the night, it was Aaron Plessinger and Hunter Lawrence out front early. Plessinger quickly got into the lead and started to run away as Dylan Ferrandis made his way into second place. Jason Anderson shuffled into fourth as teammates Malcolm Stewart and Christian Craig battled back and forth. Cooper Webb was in seventh. Justin Cooper went down on the first lap and was deep in the field. Plessinger had a slip up at on the last lap, which allowed Ferrandis to close in. But AP7 got going again and jumped ahead to continue to lead. However, a few sections later in the turn after the long rhythm section on the first base side. Ferrandis went by into the race lead as Webb, who was outside the top five, made his way into second place. Ferrandis took the heat race win as Webb held off Plessinger at the finish line! Webb launched the double and held onto second place as Plessinger came through in third, just 0.282 seconds behind the #2! Anderson came through fourth, Hunter Lawrence fifth, Stewart sixth, Craig seventh, as Derek Drake (eighth), and Austin Politelli (ninth) claimed the final two transfer spots in sneaky solid rides. Tristan Lane finished tenth. Fredrick Noren came through 12th, Cooper 14th, Josh Cartwright 16, Cade Clason 19th, Justin Starling 20th.

Update on Main Events

6:45 p.m. local time

The LCQs are up next to determine the final four qualifying spots for each main event, but we have been informed the 250SX main event will now be 10 minutes plus one lap and the 450SX main event will be shortened to 15 minutes plus one lap.

250SX – LCQ

Max Sanford nabbed the hoelshot in this one, but a few jumps into the first rhythm section Nate Thrasher swiped the lead and checked out. The battle was on for second though, as Sanford had a multitude of riders on his tail. Talon Hawkins was one of them, but ended up going down. That trend continued over the course of the next lap, with rider after rider going down, until suddenly, Sanford was all by himself in second place.

About seven seconds back of Sanford a group of riders battled for third and fourth, but one by one they all kept crashing, throwing qualifying spots back and forth like hot potatoes. Kyle Wise was able to endure the mud longer than most in third, but ended up going down as the race wound down. When it was all over Thrasher had taken the win, Sanford took second, with Ty Freehill and Deegan Hepp filling the final transfer spots.

Riders going down has been a normal occurrence all night, but this race was especially crazy. At one point one lane was almost completely clogged with stuck bikes and dirt-covered riders, all struggling to untangle themselves from each other and get their bikes free of the goop. The rain is really coming down hard now too, so expect the main events, which have been shortened, to consist of a complete comedy of errors.

450SX – LCQ

The 450SX LCQ gates dropped and as the field flew into the first turn, Kyle Chisholm blew through the first corner and slammed right into the wall along the first base side! He got up but looked pretty banged up. Vince Friese led the field until a few laps in, ending his race early. In the same corner, John Short’s Beta machine would also expire, ending his night early as well. Kawasaki teammates Theodore “Bubba” Pauli and Fredrik Noren were battling for until Pauli went down and off track. With Friese and Pauli running into trouble, Noren took off with the race lead. Justin Barcia overcame a mid-pack start to move into second place. Rain continued to fall as the riders continued to struggle. At the checkered flag, Noren, Barcia, Jason Clermont, and Cade Clason claimed the four transfer spots. Benny Bloss came up short in fifth, Justin Cooper came through seventh, Kevin Moranz eighth.

250SX – Main Event

Jordon Smith did himself a huge favor by getting the holeshot in this one, while Jo Shimoda went down on the first lap and wasn’t able to get his bike going again. Just like that, Shimoda’s night was over and his bike was left standing up and stuck in the mud in the track.

Up front Smith was running away with it, but the battle for second was hot. Max Vohland held the spot, but something went down and he found himself stuck on the track and not going anywhere. Like Shimoda, he ended up DNF'ing. That put Levi Kitchen in a battle with Phil Nicoletti for second. For a section or two the duo were side by side, but Kitchen ended up leaving Nicoletti, who later gave up a spot to Carson Mumford. But then Mumford slipped out in the mud, handing third back to Nicoletti! Riders were going down everywhere, and keeping track of who was who, and where they were, was like trying to solve a Rubik's Cube blindfolded!

When the white flag came out Smith held a solid lead, but Kitchen was closing fast. Smith was struggling to get by a lapped Hampshire, while Kitchen was taking big chunks out of Smith’s lead. When Smith came around the final corner, Kitchen came flying into the inside and was nearly able to throw a block on Smith, but just barely missed. Smith won the race, putting him in the 250SX West points lead, followed by Kitchen. Nicoletti held down third for most of the race, but was passed late by his teammate, Garrett Marchbanks, and finished fourth. Mumford rounded out the top five.

450SX – Main Event

The 450SX main event gates dropped on the final race of the night and it was 2023 450SX Champion Chase Sexton who grabbed the holeshot! Eli Tomac and Adam Cianciarulo were second and third early on as Malcolm Stewart, Christian Craig, and Jason Anderson were several of the riders down in a first turn pileup. Sexton rolled away with the race lead. Stewart then was off the track with a Tuff Block stuck under his bike. Eventually, him a flagger and a man in a black hoodie were able to dislodge the Tuff Block and Stewart got going again. He would continue to run into issues. Out front, Sexton clicked off lap after lap as AC and Shane McElrath shuffled into second and third. Tomac and Ken Roczen both got around McElrath and Cianciarulo, then Tomac started cutting into Sexton’s lead. ET3 cut the lead from eight seconds to five seconds to three seconds! However, Tomac never got close to Sexton to make a pass attempt. The Lawrence brothers Jett and Hunter battled one another. Derek Drake ran a solid 12th place. Sexton had a close call as he momentarily stalled up after Jett Lawrence tipped over right ahead of the #1! Sexton stayed up and going quickly, and Tomac was not close enough to do anything. At the checkered flag, it was the #1 who would take the main event win! Tomac held onto second as Roczen charged to a third-place finish. McElrath held on for fourth—which I believe off the top of my head is a 450SX career best. Plessinger rounded out the top five after some struggles from Dylan Ferrandis. The win allows Sexton to move into first place in the championship standings, seven ahead of Jett Lawrence.
