    Default Yamaha Blue Spot calipers

    Couple of questions -

    1) Are they all the same?

    and

    2) Which bikes were they used on?


    The reason I ask is that the XJ900S that I acquired earlier this year (after first asking about them 5 years ago) has them fitted. So, I'll need to service them at some point and want to know what seal kit I'd need to buy.

    What says TRC?

    I think they're all the same internally (pistons/pads, etc..), however externally, there are ones with a link pipe and ones without.

    A link pipe? I've not noticed a link pipe. Must have a look tomorrow.

    The early ones (think Thunderace) had a solid external link pipe between the two halves of caliper (even tho they're unibody and don't have halves). The R6 ones don't have the external pipe, but the mounts are the same.

    Yep, basically as above. Thundercat and Ace had external pipe linking the halves, R1/R6/Fazer etc didn't. Pads are all the same and they all have the same 100mm mountings. Another difference is the R1 type have the fluid inlet on the side, Thunderace ones have it on the back at the top.

    I may have some unopened seal kit parts down the garage you can have

    So, these appear to be the R1 type.

    Don't think I need any at the moment, but it's very kind of you to offer.
