2024 British Motocross Championship

The 2024 ACU British Motocross Championship season (known for sponsorship reasons as the Dirt Store ACU British Motocross Championship) is the 72nd British Motocross Championship season.

Conrad Mewse starts the season as the reigning champion in the MX1 class after picking up his fourth title in 2023.

In the MX2 class, Swedish rider Isak Gifting is the reigning champion. However he will not defend his title as he will focus on the MXGP class of the 2024 FIM Motocross World Championship and the 2024 Italian Prestige Motocross Championship.

The second race at the third round at Blaxhall was cancelled due to two race incidents and a separate incident with a member of the crowd leaving the event without enough medical cover.

The fourth round, scheduled to be held at Foxhill, was cancelled in the week leading up to the event due to low entries.

It was later announced that the fifth round at Hawkstone Park would be the first event where the ACU British Motocross Championship ran in conjunction with the rival Fastest 40 series (formerly known as the MX Nationals).
