After racing his rookie year with the Bar X Suzuki team, Preston Boespflug has signed with the Partzilla PRMX for the 2025 SuperMotocross World Championship. Boespflug finished 15th in 250SX East Region Championship with a season-best ninth at the Philadelphia Supercross in his first season of Monster Energy AMA Supercross, then finished 42nd in the 250 Class of the AMA Pro Motocross Championship with a season-best 25th overall at the Fox Raceway National opener.
Boespflug spent one year as an amateur on the Team Green Kawasaki squad (2022), so he will return to familiar equipment. The Washington native raced as #128 in 2024 but earned national number #73 for 2025. Read the full list of 2025 national numbers.
Boespflug took to Instagram last week to thank his mechanic/close friend Ty Davis for the help over their seven-year run together. Check out his Instagram post later in this post.

Punta Gorda, FL — The Partzilla PRMX Team is proud to announce its signing of Preston Boespflug for the entire 2025 250 SuperMotocross Championship.
Boespflug, a California native, will be preparing for his sophomore season as a professional by moving East to the new PRMX Team headquarters at MotoBros in Florida. The 19-year-old caught the eye of Team Owner Julien Perrier after a successful rookie campaign in this season’s 250SX East Region. Boespflug finished 15th overall in the standings with six main events and four of those results were inside of the top fifteen. However, his best finish was a ninth in Philadelphia. The Partzilla PRMX Team sees his potential and looks forward to helping Boespflug build off of his stellar rookie season.
The move to Partzilla PRMX will also mark the return to Kawasaki for Boespflug, who was a member of the Team Green Program as an amateur.
Julien Perrier - Team Owner
“We saw great potential in Preston’s abilities in Supercross this past season. He’s got a lot of talent and we can’t wait to try to fine tune all of that with him!”

“I’m extremely excited for my new opportunity to join Partzilla PRMX for 2025. I think the move to Florida will also be good for me. The move to Kawasaki feels right! I really like how the bike handles and I think they fit my style well. I’ve had my best results on a Kawasaki, so I’m excited to get back on them!”
The Partzilla PRMX Race Team was founded in 2010 by Julien Perrier. The team is based out of the MotoBros Punta Gorda location.
