    Yeh straight in fella, the only one that won't work is Ohlins legs need larger bottom yoke.

    813 have a 25mm cartridge and use 5mm spacers on the standard calipers

    204 have 30mm cartridge and don't need spacer for standard calipers

    Overall length is same for both I believe

    Yeh same length, but the 204 can't be used with Brembo GP4's so I've heard.

    It's the M4's that can't be used unless you machine 5mm off them, the hpk and gprx I believe are fine! @arthurbikemad is the man to ask

    Can the SP Brembo calipers be used on the 08 onwards fork bottoms ?

    An old post on here Steve....


    I've been told the Mono Block Brembo's will not fit the Ohlins forks as they are and I quote from Brembo
    As for the CBR calipers on the SP, not yet, be careful with the forks if FGRT204 as the fork bottom has been machined to include the 5mm spacer fitted on the standard fork and Brembo GP4RX do not fit and the forks need 5mm machining off.'

    Fgrt 813 are the forks for 08-11 but will fit 12 plus bikes and will fit all calipers as the they were made without the spacer dimension

    Fgrt 204 which I have are for 12 on bike but will fit 08 plus, caliper wise you cannot fit Brembo M4 as they require the spacer to be removed on the std fork, ohlins made the fork with the spacer dimension :(
    So you can either machine the fork mounts or calipers or the HPK calipers will fit as I have them on my bike unsure on GP

    Basically if they need a spacer on std fork they might if they don't they won't (spacer is 5mm on std)

    I'm not using ohlins forks mate

    I'm asking if the sp Brembo m4 calipers will fit in into the standard
    Fork bottoms either the normal 08 to 11 or the Showa BPF.
