Yamaha Motor Corporation in the USA has announced that the Monster Energy/Yamaha Factory Racing Team has signed new contracts with Justin Barcia and Aaron Plessinger to complete its two-rider 450 class roster for the Monster Energy AMA Supercross Championship and AMA Pro Motocross Championship series in 2019 and beyond.

Barcia, who began the 2018 season as a fill-in rider, proved his merit early on as a contender in the supercross series and quickly became a full-time team member for the remainder of the race year.

With nine podium finishes under his belt, Barcia will continue to fight for third overall in the 450MX Championship this Saturday at the season finale in Crawfordsville, Indiana.


With 10 years of professional racing experience, including back-to-back 250SX East Championships in ’11 and ‘12, Barcia will spearhead the team’s 450 efforts as a seasoned veteran in the class.

Recently crowned 250MX and 250SX West Champion, Aaron Plessinger, is set to make his 450-class debut in Monster Energy AMA Supercross and AMA Pro Motocross with the Monster Energy/Yamaha Factory Racing Team in the 2019 season. The 22-year-old Ohio native has displayed his versatile skill set in all types of conditions and will prove to be an asset to the team.

Motorsports Racing Division Manager Keith McCarty: “We’re very happy and proud to sign Justin and Aaron to our Factory Team to race our YZ450F.

“We saw great potential in Justin when we extended his agreement through the 2018 motocross season and we’re pleased with his consistent finishes this summer. Aaron has been with Yamaha for over a decade and moved up through the ranks with the bLU cRU family. He has been supported by Rock River Yamaha in his amateur career and most recently with Monster Energy/Yamalube/Star Racing – they have helped to prepare him well, along with his undeniable talent, which is obvious from his dual championship-winning season in Supercross and motocross. We look forward to great things in the future from both riders in 2019 and beyond.”

Aaron Plessinger: “Signing with Yamaha for the 450 Class is amazing! I’ve been with Yamaha since 2008 and we have had an awesome relationship ever since.

“I feel like it’s going to go really well for me next year, just being on a great team with good people around. I can’t wait to start testing and get my bike dialled in!”

The 2018 AMA Pro Motocross Championship concludes this Saturday, August 25, in Crawfordsville, Indiana for the Ironman National. Both Justin and Aaron are set to represent the U.S. Team at the upcoming Motocross of Nations on October 6/7 at RedBud MX in Buchanan, Michigan.
