Dual MotoGP World Champion Casey Stoner will step away from full time motorsport racing in 2014, yesterday’s Sydney 500 concluding his one-year deal with Red Bull Racing Australia in V8 Supercars.

Stoner, 28, endured a challenging first year in the Dunlop Development Series, opting not to return for a second season next year.

The weekend’s Sydney event saw Stoner finish in consistent fashion with 12th on Saturday and ninth on Sunday.

“I would have liked more time in the car, for sure, but I’ve enjoyed the challenge of driving and I can’t thank Pirtek, Red Bull, all my sponsors and fans for supporting me this year,” Stoner said.

“I feel sorry for the team because I don’t think we ever really got to show our true potential but this weekend the car was great.”

Stoner is expected to remove his involvement in motorsport altogether for next year at least.
