2025 Monster Energy AMA Supercross 250SX East/West Showdown - Salt Lake City
By Team TMX on 10th May 25
The Dave Coombs Sr. 250SX East/West Showdown at the Salt Lake City finale of the 2025 Monster Energy AMA Supercross Championship was dominated by Star Racing Yamaha's Haiden Deegan who grabbed the holeshot and was never challenged for the lead - backing up his win the week before when he wrapped up the Western Divisional 250SX Class Championship.
Behind Deegan, the three-rider fight for the Eastern Divisional 250SX Class Championship was settled with a wildly dramatic battle that saw Red Bull KTM Factory Racing's Tom Vialle finish in third place and earn a consecutive Eastern Divisional 250SX Class title.
Vialle started in second with the other Eastern Divisional contenders, Monster Energy Pro Circuit Kawasaki's Seth Hammaker, in fourth, and Rockstar Energy Husqvarna Factory Racing's RJ Hampshire, in 14th.
Along with Western Divisional rider Red Bull KTM Factory Racing's Julien Beaumer, the four riders threw down for an epic battle that saw several position changes, aggressive passes, and a take-out move that put both Hampshire and Hammaker on the ground. That crash allowed Vialle to slip past and pull the championship back when it had appeared lost. Hammaker made a charge but could not regain the time lost to Vialle.
At the chequered flag Deegan cruised to his fourth win, Beaumer took second, and Vialle took third place and secured the 250SX Eastern Divisional Championship.
