Jørgensen won the title by finishing second in the opening race and then signed out of the 2012 series with another second place in the final race after a tough, hard-fought-for comeback from a serious car accident more than 12 months ago.
He also dedicated the win to his Father, who died in January.
He said after the win, “I’m really happy to have won the championship for Suzuki especially because of the serious injury I suffered in a car accident.
“Even now my arm is still not 100% so it’s been great to win the title.”
Three times Champion Nicolai Hansen finished the MX1 season in runner-up position aboard his RM-Z450 while MK Motorsport Suzuki’s Catja Rasmussen collected her third consecutive Women’s title.
In the two-stroke class, 13-time winner Soeren M Ebbesen dominated the season aboard his RM250.
