Chambers KTM has confirmed that former British Champion Cas Valk will be lining up at the final round of the 2026 Motul ACU British Motocross Championship (MXGB), at Blaxhall on Sunday, September 27th.

It has been a disrupted season for the Dutchman. After starting 2026 on TM machinery, Valk and that team parted ways by mutual agreement mid-year, leaving him without a ride. British based team Chambers KTM moved quickly to sign him, reuniting Valk with the KTM package on which he had previously enjoyed success. The pairing looked strong from the outset, with Valk quickly finding form, only for a crash at a Dutch Masters of Motocross round to sideline him before he could make his planned MX2 World Championship debut for the team.

Blaxhall will be his first race on British soil since the injury. Valk’s MX2 return comes at a stacked round eight, with an undercurrent theme of returning British champions lining up alongside current champions, underlining the strength of the field Valk will face on his comeback.
