Just had a phone around for a Kawasaki Cam Chain, Aftermafket M&P and others like them,about £68. Genuine Kawasaki part £29. It goes to show its not always cheaper going the aftermarket way.

If its an older bike Kawasaki will put the parts on special to clear old stock.Common practice in the motor trade.

Very often the case for car manufacturers parts to be cheaper than pattern , Mercedes handbrake shoes retail price complete with all new springs etc was cheaper than trade price for pattern parts without
