This week put the M Sport in for an oil service and software update ( 4hrs ) and following this work was then informed my rear wheel had cracks in it. The service manager stated that it was probably in the laquer and not the CF itself anyway for safety reasons etc a new rear wheel was ordered overnight and fitted. ( the other issue I experienced over a year ago was the neutral issue. - fixed with the pressure regulator and new clutch plates. ). Just waiting on the leaking calliper issue to raise it head. Other than that - fantastic bike !
