    I dare say if it was middle o the season I would be slightly annoyed, but Scotland in January, am no riding anyway, so if it needs fixed before the season plenty time

    Thats penetrated the lacquer... can't think how that could be removed without affecting the integrity of the rim.... shambles in places with this bike.

    Your no mug, glad to hear that... Soof has already asked the next question... where's the leak coming from....

    I'd whip off that caliper as curiosity would get the better of me...

    They will spend more fixing the issue for all bikes now plus those with carbon wheel damage.

    Their business case of using same calipers for several bikes is now into the red!
    GS’s also report the issue.

    I have an RT with Brembos and absolutely no issue

    Re: Gen4: check your brake calipers. Leakage. Danger.

    Is this a problem with early bikes or new ones as well? I’m due to collect my new bike this weekend and wondering if this issue has been sorted on later production bikes. Because if BMW know of the issue then one would think they’ll rectify at the factory. Mine is a Jan 2020 produced bike. I’ll ask the question when I go to collect.

    Sadly, it’s the way most companies are going, in trying to cut costs. Clearly, this has gone wrong for them though. Ultimately, they should have stuck with Brembos on the RR’s at least, their flagship model.

    On a positive note, most well respected journalists say the Hayes brakes have a better feel and less snatchy compared to the Brembos. Hopefully they’ll sort it, annoying as it is...
