Kawasaki has confirmed Chris Vermeulen will not ride the ZX-10R again until the final official test at Phillip Island, a week before the start of the 2011 World Superbike season.
The Australian returned to action for the first time in six months during team testing at Sepang, though he would only complete mileage on one of the four days there.
Satisfied with his feeling aboard the new bike, Vermeulen will now travel back to his native Australia, where he will continue his recovery from knee surgery in an effort to be fully prepared for the season ahead.
As such, Vermeulen will not be present at the first official group test at Portimao later this month and will instead be seen next at the Phillip Island trial.
“Chris rode on day one of the Sepang tests and was very impressed with the performance of the new bike,” team manager Paul Risbridger said. “He has made great progress with his knee recently, and his recovery is well on schedule.
“After day one we all decided that he did not need to run on track any more at this stage and it was better for him to go home and carry on with his rehabilitation. We also came to a consensus that there was no point in him coming all the way back to Europe for the Portimao tests, as it would just interrupt his overall recovery.
“Riding the bike is not assisting his recuperation at this stage, so Chris will carry on with his very effective programme of physiotherapy and exercise so that he is ready when it matters most, at the start of the new season.”
In Vermeulen's absence, his team-mates Tom Sykes and Joan Lascorz completed a successful four days of running in Malaysia.
