The STTARS Supermoto race at Auto Club Speedway in Fontana has been a tradition for eight years. This year there was a new twist on the weekend. The race is always run during the AMA Superbike weekend on a temporary track in the confines of the speedway. This year, for the first time, part of the three-day event included one round of the newly created AMA Racing XTRM Amateur Championship Series. This series makes eight stops on the calendar before crowning several AMA Amateur titles. Five of the eight races in the series are run in conjunction with the XTRM AMA Pro Racing Supermoto Championship like this Fontana event. Saturday's festivities also piggybacked Don Canet's STTARS 3-Brothers Super TT Southern California Series.

The two big winners from the weekend included Vet 30+ and Vet 40+ victor Jimmy Roberts (pictured 832) and the young Dustin Hoffman (no relation to the actor) taking the 250 and 450 classes. Hoffman and other AMA Pro-licensed riders are eligible to race the amateur event in the 250, 450 and Unlimited classes but are not eligible to earn points for the amateur championship.

When stuntman Jimmy Roberts is not doubling for actors such as Owen Wilson, he's at the races. In Fontana, Roberts was on a mission and seeking a little redemption after getting stuck in the mud during round one of the STTARS Series. Roberts' biggest rival in the 40+ division is former pro motocrosser and Team CHM Exhaust Manager, Roger. Yes, old guys still go fast.

In the heat race, supermoto legend Rick Pearce nailed the start aboard his trusty Honda CR500R with Roberts and Hensley in tow. Pearce held the two at bay for a few laps until the duo eventually got by. From there it was a battle between the rivals Roberts and Hensley. Chipping away and keeping the pressure on, Hensley waited until it was the right time to make the move. Roberts' bike was all over the place and he couldn't keep the rear tire from swapping around on the pavement. Hensley seized the moment, made the pass and led all the way to the checkered flag. The heat race was there just to set the grid positions for the point-paying main event.

After a few chassis setup changes, Roberts was set for the main event. This time Roberts wasn't about to let Hensley get the best of him and he got a solid start and the early lead. Hensley, on the other hand, didn't fare as well and found himself in third behind Pearce. Hensley did make his way to second fairly fast and it looked like there might be another showdown in the main.

Up front, Roberts looked like a different rider compared to the heat race and held Hensley at bay each and every lap. There were a few laps when Hensley looked like he started to close the gap but it was too little too late and at the finish line it was Roberts the victor, Hensley the first place loser and Pearce picking up the last rung of the podium.

Roberts was also the spoiler in the Vet 30+ division. He battled in the heat race with the likes of KTM-mounted Craig Peyron early on, but Roberts would set the tone for the main event with the heat race victory.

The main was a carbon copy of the heat with another textbook holeshot by Roberts and a wire-to-wire victory. By the finish there was a five-second gap between first and second. There was a nice battle for third in the main between Mike Ingle, Steve Isenhower and Mike Deloach. Ingle and Deloach swapped positions several times for the third spot but in the end Deloach fell back to fifth while Ingle and Isenhower finished third and fourth. Peyron took second for the day, but it was a lonely ride with Roberts out front and the race for third a good distance behind.

The second big winner of the weekend was Dustin Hoffman aboard a CHM Exhaust Honda Pro Oils-backed CRF250R. In the 250 class he had to contend with young phenom Ryan Kearns and Jeff Ward's son Brandon - talk about pressure.

In the heat, Hoffman took the early lead with Ward, Jake Thompson and Kearns hot on his tail. Kearns was the first to make something happen by snatching third away from Thompson. Hoffman had a few seconds on Ward, but the race was far from over. With only a few laps to go, Hoffman made a mistake in the dirt and went down giving the lead to Ward. Hoffman would remount to finish second but the pole position for the main would go to the young Wardy.

The main event was another story for Hoffman (pictured, 127) and he wasn't about to make the same mistake twice. Starting in the second spot next to Ward, Hoffman was still able to get out front entering the first turn. Thompson fell into second with Ward, Kearns and Zach Warnock rounding out the top five.

The leader, Hoffman, held steadfast to the helm and never took any chances. Ward and Kearns made their way past Thompson early on but neither rider was able to make any headway on the leader.

Back in the pack, 400 AM winner Tyler O'Hara started to show some speed in the main and battled his way to fourth for a moment before stalling his bike in the dirt. This mistake gave the position back to Thompson and, at this point, Warnock would take and hold down fifth until the finish.

At the flag, Hoffman cruised in for the victory, Kearns in second and Ward finished third. But since the first place rider is an AMA pro, Kearns left Fontana the point leader for the AMA Amateur Championship.

Hoffman (pictured, right 127) would also come back to win the 450 class over Jake Thompson and Dillon Van Way, making it almost a clean sweep for the weekend. In the $1,000-purse Unlimited class, Hoffman would finish in the money behind Japanese rider Kiyoshi Saai.

In the Mini-Moto 125 class, another member of the Ward family was hot to trot-Ayrton Ward. Just like his father, he knows the taste of victory. Little Ward not only won his heat race but came back to take the main event as well. Ward bested the likes of Jason Uribe and Andrew Lee. Alain Ward, another brother, finished fifth. Between Saturday and Sunday's race, there were four different Wards on the track, talk about a dynasty.

The Novice class was one of the largest races of the day with 22 riders on the grid. The Kearns boy was back again in this class aboard a 300cc KTM two-stroke to compete with all of the 450 and larger displacement bikes in the field. Kearns (pictured 990) had the field pretty covered with wins in both the heat and the main but it was the action behind the leader that made the race.

In the heat, Art Kawaguchi and Donnie Bales swapped a little paint going for second. This little tussle allowed the field to catch up and before he knew what hit him Kawaguchi was fighting for fifth. John Levy and Zach Warnock wanted to be on the front row for the main and they made sure to secure it.

In the main, it was again Kearns with the early lead and he would eventually check out. Bales, who placed second in the heat was off his game in the main and finished a distant fifth. Levy and Warnock faced off again but this time it was for second with valuable series points on the line. Warnock pulled a few tricks out of his basket and applied some pressure to Levy but the attempt was futile. In the end, Levy kept Warnock at bay for second and Tyler O'Hara, who missed the heat race, finished third in the main from the back of the grid.

Round two of the AMA Racing XTRM Amateur Championship Series will be held at Infineon Raceway on May 16-17. For more information on that series, visit xtrm.com/supermoto. And to learn more about Don Canet's STTARS Series go to supertt.com.
