The S Briggs Commercial Motocross team is excited to announce the signing of the talented 12-year-old Harley Marczak on a three-year programme, which will take him through the 125cc phase of his development as a rider.
Harley, who hails from Manchester, has been racking up the accolades in his short career, including finishing runner-up in the Big Wheel 85cc class of the 2025 MXGB British Youth Motocross Championship, finishing just seven points from the top spot.
On top of that, he finished sixth in the Bridgestone British Masters, even though he missed a round and was the top British rider in the Junior World Motocross Championship, where he finished a fantastic tenth. He was also part of the winning British team that won the 85cc class of the Coupe de’Alvenir, where he was also the class winner, putting on a fantastic display in the mud in Belgium.

Bradley Briggs from the team said of the signing, “We have watched Harley during the 2024 and 2025 seasons, and have seen the fantastic performances he has put in, not forgetting he is only 12 years old (13 end of November). Harley, his family, including his Grandparents, put in 100% effort both on track and in the paddock.
“He is growing stronger every day, so as a team, we have given him the opportunity to compete on a 125 in the 2026 season. His programme will see him competing on a 125 in the British Championship, in EMX125, and at selected international races. We are looking forward to an exciting journey with him.
“As a team, our goal is to have fun and create a great family environment in the paddock with our focus on youth rider development in the UK.
“It’s an area where we want to support the MX Federations in Britain to provide the up-and-coming riders with as much support as possible to aid their European journey.
“We look forward to welcoming Harley into our 2026 Squad.
