its a shi&e piece of plastic seal, the size of 20p.. Real piece of cr@p worth 2pence that demands the whole bike being dismantled in order to get to it. Like 9hrs of labour at a specialist. Had mine done twice before I sold the bike.. Unbelievable that BMW did not care to design such a weak link to be easier to get to, or make it stronger.
It was the single most serious reason why I sold it. That and the fD failure it sustained.

. For me I lost confidence in its reliability so she had to go.


.The dealer recalibrated it but haven't tested it yet, will rely on odometer instead.
