While we might not ever know if that specific claim is true we DO know that 1 out of 6 BMW final drives fail in every competitive rally the past few years. These are the same rallies that no FJR final drive has failed. The statistics look more and more grim as the failure rate can be predicted with increasing precision.Yeah yeah yeah, final drives shouldn't fail. And they don't for probably 99% of the population of the BMW bikes. The failures get a lot of publicity, in part because the marque is viewed as odd and overpriced by so many folks.
And I don't think they're getting publicity because of the marquee or price, but because they're leaving riders stranded at the side of the road and losing rallies they'd otherwise win! I'm the winner of one of those rallies because a well serviced final drive couldn't keep from inverting it's guts for 8,000 miles.
But, far be it from me from dissuading you from guzzling the cherry flavor drink. I've found that BMW folks tend to have to come to the realization themself. Doing it on FJR forum probably doesn't do much good.
Meanwhile good luck I really do hope BMW can get it's act together and fix the beloved brand.
