It does seem to be a quality control issue or design fault? or as someone said they are just consumables. Never the less you would wish to get more than 3700 miles out of a set. Good advert for Motul 300V fully-synth 15/50?
I know that the 999 has a redesigned engine but the principles are the same, are there any recorded failures of rockers on that bike yet?
