New clutch actuation push rod seal to suit all K models up to K1100.
You need to be careful in replacing these as they are only small and if you damage them, they will leak and they are expensive.
Apparently no longer from BMW
Please note that these seals must be fitted with the lip pointing towards the back of the bike. If it is fitted the wrong way round oil, can migrate down the pushrod to the clutch and it is not possible to fit the pushrod on the K75 model unless you remove the gearbox.
