I've recently purchased a used 2011 Kawasaki ZX-10R and on my first ride noticed a problem with the traction control.
The bike was delivered by the dealer on Saturday 25 February and my first ride on Sunday 26 February lasted approximately 30 miles before problems started, ending my ride after a total of approximately 40 miles.
The bike had a new rear tyre fitted so I set the power mode to L and the traction control to 3. After approximately 30 miles of riding, whilst holding the throttle steady at approximately 4000 rpm the bike began surging. I pulled over and set the power mode to M and traction control to 2 and continued to ride home. The bike would rev up to 4000 rpm but if I opened the throttle the revs would die, and if I shut the throttle the revs would shoot up to 6000 rpm. I rode the bike lurching for a few miles before it cut out and wouldn't restart.
After a few minutes I managed to get it started but every time I tried to rev it the engine died and the traction control lights 1,2 and 3 would flash along with an amber light on the right hand side of the dashboard.
EDIT: I returned the bike to a dealer (run by the same group) on Sunday afternoon around 3 pm. I called the dealer around 9 am on Tuesday 28 February and was told the bike still hasn't been diagnosed and they will look at it in the next 24 hours.
