The technical problem that delayed the launch of the 2011 Ninja ZX-10R has finally been unveiled by Kawasaki Heavy Industries.
The company said that the intake valve springs in some of the motorcycles tended to surge and put pressure on engine performance if the vehicle operated under high rpm in conditions such as on a racetrack.
Kawasaki said that the camshaft, valve springs and spring retainers for intake valves are being replaced in the vehicles produced so far, in order to prevent the valve spring from surging.
All the new vehicles being produced will also be made with the latest spare parts.
Michael Johnstone, Sales and Marketing Manager for Kawasaki Motors UK, hailed the work of the company's engineers in detecting the problem and finding a solution for it.
He said: "While we have been thinking about Christmas and the new year, a team of engineers in Japan have been exhaustively testing new high performance components for the stunning new Ninja ZX-10R.
"With the dealer launch of this and other incoming range models on 27 January across the UK, this news is the best possible start to 2011 for Kawasaki dealers and riders."
