    It's not hard, but it's a lot of fucking around. So mounting the standard calliper is likely the easiest option.

    My mistake ... I thought he was referring to the axle that needed heat treatment ...

    How about making a collar to bolt onto the 5 bolt 110ml dia 17 inch rim and bolt the 6 hole 150 dia original disc.
    to that.

    The ting is that with the original disc is 20ml further out on the fzr rim from centre of rim than the bandit one so possibly a 20 ml plate made would mean I could use the original calliper and get one spacer made up to go between the calliper mount and rim with a reducer into the rim.

    Thoughts on that please?.

    That would work nicely I reckon.

    Ok I have the sprocket side spacers being made as I type and should pick up on Monday.

    Then I can get an accurate measurement of the spacer I need for the brake side between the rim bearing and calliper mount bracket.

    I see there are different grades of aluminium plate available and wonder which grade would be best to ask for as I will have to get a piece or offcut from somewhere and will have to be 25ml thick as I think it will have to be 20ml thick as the plate itself and be able to lath it down to leave a flange to fit the disc over.

    So what grade of aluminium please do you think??????.

    Because the bulk of the force is held with the friction of the two surfaces, if ya located it on dowels and held it tight it can be soft as and never cause a problem.

    Wheels are super soft all things considered, after all.

    It's not that fucking easy either. In most cases the first thing you need is an accurate oven capable of around 900deg, which isn't very much below the temperature that will see your swingarm a puddle.

    Unless you know exactly what alloy it is, the heat schedule and the correct tempering procedure don't bother, it's much safer to make a bracket that goes completely around the swingarm tube and clamps on there. I'd bung a couple of monel rivets in there too, belt and braces thing...
    Go soothingly on the grease mud, as there lurks the skid demon

    Flat plate in 25mm thick is going to be hard to find in anything but the more common grades ... ie - 5005/5251/6061..
    plate in 5083 would be the go...5251 & 5083 in the most common plate/sheet used in boat building..try a boat builder
    for offcuts..
    Round bar in 7075 would be far the best..
    But really any of the grades will do , its a short spacer under compression with a great bit of steel up it's guts..
    But as theres a seal that also runs on it the harder grades will last longer 5083 or 7075...

    Yer na sorry mate.
    You got the wrong part.
    The axel spacers are being made of steel.
    The spacer i'm meaning is to bolt onto the 5 bolt 110ml diameter holes and be about 20ml thick and then mount the original disc on that 6bolt 150 diameter holes.
    Why I think I need a piece 25 ml thick is so I can take a shave off one face and leave a flange to fit the disc over like a rim has.
    So I think I need a piece of flat plate 25ml thick by about 180x180ml to get the piece cut out of.
    So what grade as I don't know if I need a heat treated or treatable one or just any grade.
    I think the 5083 on some literature I read it said don't use in applications over 60 deg c but don't know what that really means and if the brakes were worked hard weather the heat would trans fer to the spacer and if so how much and would it matter.
    Hope that's clear.

    You're good to use whatever you can get in my opinion. The rear brakes never get that much of a work out that you're going to over heat the plate, and bolted to the wheel it wouldn't distort anyway.

    Cool thanks Drew.

    Getting quite excited really.
    Fairings off at the moment and getting quite good at melting cracks together with the soldering iron (even making some new bits to weld into where the odd pieces are missing) then I will put a layer of fibreglass over to brace the cracks.

    Should do one of them photo things A
