The 2015 Lucas Oil Pro Motocross Championship celebrated Independence Day on Saturday with the sport’s annual tradition in Southwest Michigan, as the Red Bull RedBud National signified the seventh round of the season.

It was a memorable day for the Yamaha brand, as it claimed the overall win in both classes for the first time since Southwick in 1998.

One week after he earned the first overall win of his 450 Class career, Autotrader.com/Toyota/Yamaha’s Justin Barcia went back-to-back, exactly six years to the date of the inaugural series victory for Joe Gibbs Racing’s motocross effort at RedBud in 2009.

Red Bull KTM’s Ryan Dungey, championship leader in the 450 Class, made the first statement of the day by garnering the Bud Light Fastest Qualifier.

When the opening moto got underway, he positioned himself inside the top two behind Barcia, who claimed the Motosport.com Holeshot Award.

Barcia and Dungey set a torrid pace early, which allowed them to eventually open a double-digit margin over the field. On lap seven, Dungey was able to make a pass for the lead after patiently waiting for an opportunity to arise.

Once out front, he never looked back and went on to earn his fifth moto win of the season by a margin of 3.232 over Barcia, who kept Dungey in sight the entirety of the moto.

RCH Soaring Eagle/Jimmy Johns/Suzuki Factory Racing’s Ken Roczen, the defending series champion, finished third after working his way forward from a fifth-place start.

When the gate dropped on Moto 2, Barcia put his Yamaha out front again to sweep Motosport.com Holeshot Awards for the afternoon, brining his season total to six.

Dungey slotted into second and settled into a pace that allowed the lead duo to pull away from the field once again. Barcia kept Dungey approximately two seconds behind him throughout the moto, but in the late stages the KTM rider picked up the pace and began to pressure the lead.

He got within a bike length of Barcia over the course of the final two laps, but was unable to make a pass as they battled both increasingly challenging track conditions and lapped riders.

Barcia went on to a wire-to-wire win by 1.651 over Dungey. The pair tied for the overall victory with identical moto scores, but Barcia’s triumph in the final moto awarded him the tiebreaker. Roczen again followed in third after starting fourth.

Dungey added to his lead in the 450 Class standings and moved to 44 points ahead of Roczen, while Barcia asserted his third standing. He moved to within 63 points of Dungey and 19 of Roczen.

Defending champion and Yamalube/Star Racing Yamaha rider Jeremy Martin emerged with his fourth overall win of the summer after late passes for the lead in each moto gave him a 1-1 sweep.

Martin’s second consecutive win at RedBud also helped him reclaim the points lead following a 17-point swing in the championship standings.

Martin established himself as the rider to be in the 250 Class after earning the Bud Light Fastest Qualifier in the morning timed practice sessions.

When Moto 1 got underway, Martin positioned himself up front but missed out on the Motosport.com Holeshot Award to Monster Energy/Pro Circuit/Kawasaki’s Joey Savatgy, who crashed out of the lead on the opening lap.

That allowed Martin to assume control of the moto, with his teammate Cooper Webb and Red Bull KTM’s Marvin Musquin, the entering points leader and winner of the previous round, following in second and third.

Martin’s lead lasted for five laps before Webb closed in and took over the top spot. One lap later Martin lost another position to Musquin and soon found himself fighting to stay on the podium.

After briefly giving up third to Rockstar Energy Husqvarna Factory Racing’s Zach Osborne, Martin retook the position and started his march back towards the front.

Musquin came back under fire from Martin on lap nine and relinquished the spot to set the stage for a showdown between the Star Racing rivals and teammates.

Musquin encountered misfortune on lap 11 when a brief fall dropped him to fourth behind Osborne and would not recover. Out front Martin consistently closed his deficit to Webb and a battle began between the pair in the closing laps.

After carrying too much speed into a corner Webb overshot a turn on the final lap, which allowed Martin to make an inside pass and steal the win by a margin of 2.991. Osborne rounded out the podium in third, with Musquin fourth.

The second moto saw GEICO Honda’s Christian Craig claim the Motosport.com Holeshot Award and as the field shuffled into place on the opening lap, Musquin, Webb and Martin once again positioned themselves in the lead group by slotting into second, third and fourth behind Craig.

A battle for second between Musquin and Webb allowed Craig to open a gap during the first couple laps before Webb was able to make the pass stick and take over second on lap two.

Musquin continued to lose ground in the ensuing laps and soon gave up third to his championship rival Martin on Lap 6. He would eventually drop out of the top five.

A couple laps later the focus of the race returned to the front as Webb closed in on Craig and made an aggressive pass for the lead on lap eight. He was able to pull away quickly and appeared to be in full control of the moto.

However, with the overall win in his sights Webb made a costly mistake on Lap 13 and fell. At that same moment Martin was making a pass on Craig for second, but it turned into the lead as both riders rode by Webb as he picked up his bike.

Martin was able to pull away from Craig easily, while Webb reentered the action in fourth behind Osborne. The reigning champion went on to secure the overall win by 4.947 over Osborne, who passed Craig for second with two laps remaining.

Craig held on to finish third for the first podium result of his career. CycleTrader.com/Rock River Yamaha’s Alex Martin was fourth, with Webb fifth and Musquin sixth.

Martin’s fourth overall win of the season (1-1) is the most in all of Lucas Oil Pro Motocross. Osborne finished in the runner-up spot (3-2), while Webb managed to stay on the podium despite his adversity in third (2-5). Musquin finished sixth overall (4-6), his second worst result of the season.

Musquin entered RedBud with a 10-point lead over Martin in the 250 Class championship standings, but a 17-point swing in Martin’s favor now puts the defending title-holder back top the points for the third time this season.

He carries a seven-point lead over Musquin into the next round of the season, while Osborne currently sits third, 91 points out of the lead.

The Lucas Oil Pro Motocross Championship will take its second break in action of the 2015 season next weekend before returning to competition on 18 July from Spring Creek MX Park in Millville, Minnesota.
