There was bitter disappointment for James Bushell, Al Abdulrazzaq’s only title challenger, who had an electrical problem at the start and eventually retired on lap three with his title hopes in tatters.
Sweden’s Lars Akerblom led for seven laps from Jeremy Perez, with Al Abdulrazzaq moving up from fourth to second after passing Christophe Agostinho and then Perez.
A lap later, the champion hit the front and disappeared off into the distance to take the chequered flag and the win by 25.34s.
“It was a great race for me and a great way to keep the title,” said the Kuwaiti rider. “I was being patient, sitting in fourth I think, and was keeping an eye on Bushell and then I saw him break. So after that I knew the title was safe so I pushed hard and took my opportunities.”
Perez piled the pressure on Akerblom and passed him on lap eight to take second and his best result of the season, with Akerblom third.
Agostinho crossed the finish line in fourth ahead of Patrice Pellier, with Marcin Senda getting his best finish of the year in sixth.
In the Freestyle, UAE’s Rashed Al Mulla secured the runners-up slot in the championship standings with his win, with Slovenia’s Rok Florjancic sealing his fourth successive UIM-ABP Freestyle world title after being beaten to second place by the UAE rider.
