    Maybe, but they were still fine in the Wing after 8 years/75k miles: I
    only changed them because I asked here if it was worth doing while I
    had the forks out.

    Fecking nightmare ever since.

  2. 10 quid or so extra is bearable and Honda will probably be using Toyo
    bearings, but 50 quid is taking the piss.

  3. Depends a lot on road conditions. My steering head bearings used to last
    for utterly ages, but sometimes they don't[1]. My mileage since coming
    here has plummeted, but on the UK motorways and roads a set of head
    bearings was lasting 60 to 100k. The state of Irish roads has probably
    slashed that to 10k.

    [1] Best one was a recently fitted set of head bearings was notched by
    plunging down a pothole in Hounslow, accompanied by a loud '****!' which
    got some old biddy staring daggers at me from the pavement.

  4. They can be, for non-standard stuff. Standard fitments are usually
    cheaper from them though, especially if you take the Volvo example[1].
    M&P obviously stock the more demanded odd-fit stuff relevant to bikes,
    BSL would have no need to, unless loads of people started to ask for
    them.

    Another thing to bear in mind though, is that bearings are made to
    different tolerances depending on who's specifying them. Toyo are the
    best, exceeding SKF and all of the others.

    [1]First Volvo I had, a 144 estate, needed a propshaft bearing.
    Something like 30quid with a nice Volvo box - a tenner from the local
    bearing stockist for exactly the same bearing from the same maker - SKF.

    Given the roads round here, and the fact that this appears to have a single
    notch bang in the middle, this sounds *very* likley

    The muttering was at having to change them after less than 25K miles.

    I used standard cheap SKF bearings from a local engineering supplies
    firm. Sorted.

    The sprocket carrier bearing on the Bandit recently failed, after 57K
    miles. I have a replacement bought from a bearing suppliers for 4 quid.

  8. That's just bizarre. I've never heard of any bike going through wheel
    bearings at that rate.
