Triumph country HQ told me in 2023 they were paying for it... but several mechanics told me that dealers actually cover it (Triumph at best reimburse brake fluid if you can bare with the process), and I even have to cover for one (that Triumph HQ never reimbursed despite their promise). I don't know which one is the most frequent; but in all cases, this dilute the issue enough for Triumph HQ not even really counting how much bleeds there are, and not really paying for it all.
