    G'day All,

    I have 08 Motovert Pro 125 with Marzocchi forks and the brakes had little feel and the firm squeeze required to slow the bike down quickly fatigued my forearm. They were slightly better when I replaced/bleed the fluid but they were still the worst brakes I have ever used on a bike. They are large single piston items and seem to be the standard issue on many of the Marzocchi forks.

    After a bit of research on here I went with the twin piston GPX brakes from DHZ and they are fantastic. The lever pull is softer with great feel and allows me to effectively modulate the braking power the way you should be able to. I wasn't 100% sure about the fitment when I ordered them but they bolted up no worries - 51mm centre to centre caliper mount.

    Best mod I have done so far. Here is a link in case you might be interested.

    Cheers.

    Yer I can vouch that these are a sweet brake setup. They have a smooth action and provide powerful braking. I've been on a few enduro rides and am using the front brakes constantly and they have yet to overheat or fail!!!

    I agree, Motovert RX brakes are shoddy. Too heavy and brake poorly however this brake wouldnt be legal because it doesnt have the senor to click it and activate the tailights :(

    I just measured... They'd fit tho :p

    That caliper is to suit a floating disc, so yeah you could use them if your replaced your disc too.
    It may need a custom mount to suit the bolt mounting pattern and offset of your disc to work on your fork's too.

    Here's one style of a Floating Disc,

    [​IMG]


    These calipers look similar style to the GPX caliper.
    You will need to ask the seller the bolt pattern and what size disc it fit's too.

    What makes the link i added require a floating disk? from memory its a 200mm disk, I might have a look for them. I did just notice the mount is 40mm apart and i think the RX125 was 51mm, dont know how i missed that!

    Off that chart it was #3 and he rear #14. I managed to get 2 sets of each for $32 ;)

    So i guess i will wait till this set of pads burn through and get THIS set and just use the caliper (so i keep the brake light switch).

    Thanks heaps!

    You would be able to swap the switch over onto that new master, they have the screw hole's underneath
    The master that come's with that caliper might be bigger capacity than the stock RX125 master to use with the twin piston caliper.

    The Brembo caliper you linked earlier doesn't have slides on it.
    The slide's allow the caliper to centralise itself onto your fixed disc.
    It would end up pushing on one side more.
    The floating disc's have a fixed mount for the centre section, and the braking area is able to move around left and right a little on the 4 bolt's that secure it to the centre hub of the disc.
