The shortened FIM X-Trial World Championship 2021 season, the indoor version of trials held on manmade sections in stadiums, was contested over two X-Trials.
The X-Trial season is usually held from winter to spring, but winter was canceled due to the coronavirus pandemic. Five indoor trials were planned to be held over October and November once the outdoor trial season finished, but three were canceled, leaving only two X-Trials.
The opening X-Trial was held on November 6 at the Poliesportiu d’Andorra, in the small country of Andorra in the Pyrenees mountain range. Although the king of X-Trails, Repsol Honda Team rider Toni Bou lost seven points in Round 1 to finish fourth, he aced Round 2 to go head-to-head with his longtime rival Adam Raga (TRRS). Raga lost 11 points, while Bou had another perfect run to win the opening X-Trial convincingly.
The Second and last X-Trial was held on November 21 at the Cathedral of X-Trial, the Palau Sant Jordi in Barcelona. Bou finished Round 1 the runner-up, but dominated Round 2 going into the finals. Raga and Jaime Busto (Vertigo) were both knocked out by this stage, giving Bou the championship. Bou nonetheless went on to dominate the finals to win, securing his 15th consecutive X-Trial championship, and combined with his outdoor victories, his 30th consecutive Trial World Championship title.
