    Gearing.....

    Has anyone used the primary gear an clutch of a KTM dirtbike in the XC 525?
    I`m rebuilding a friends quad, been running 16-36 sprockets, but still has way to high RPM.
    This quad is riden way too much on the fast roads, so it needs the higher gearing.
    Any other solutions for this.....?

    I think you can get a husaberg primary gear that will fit not exactly sure what model but it has fewer teeth than the ktm version.

    Ok, will need to look into this.
    Just wondering if the quads larger clutch is for the gearing only,
    or if its for the bigger load caused by more traction.....?

    larger clutch as in you mean the gear and outer hub ? yes gear is larger, hub is the same as the 07 dirtbike. Clutch pack is basically an 07 dirtbike unit.

    you just swap the gears, don't need to change the inner clutch hub, it's the same as the 07 dirtbike as well

    Sure the dirt stuff works. Outer clutch hub and primary gear and the freewheel gear outer hub. Bought a shelf dozen quad clutches inner hub and plates and fibers from failed quads to use them on dirt bikes as I had the primary gears and outer hubs.Less power needs lower gearing. More power can be geared up....Bob

    Here you see the bike primary gear on top, and quad closest to camera.
    Must use bike e-start gear hub, or as i do, the whole e-start gear, since the primary
    gear of the bike is not a direct fit.
    Will be interesting for the testride.....

    Can you please post up a list of the parts you need for this including ktm part numbers. And let us know how it goes. I have my xc on the road and always run out of revs. In fact I'm sure that's why I blew it up!

    59032000033 PRIMARY GEAR 33-T
    59032000476 OUTER CLUTCH HUB 76-Z/20-Z 01
    0912060106 AH SCREW DIN0912-M 6X10 10.9 (x6 pc.)
    59040025000 FREE WHEEL HUB

    This should be the parts needed, just replacing the freewheel hub of the e-start, and re-using
    the e-start clutch/ freewheel of the quad.

    Got the XC back on the road today.
    Gearing seems much better, but have not done a full road test yet.
    Final drive is 16-37, looking for 36 rear sprocket.

    All parts for primary gears is a direct fit, i used a 2006 EXC 450 as donor.
    The e-start kit for the RFS bikes is no longer awailable, but you might
    get the e-start freewheel hub as a single part....?
    Have not confirmed this, as i had the parts in house.
    One nice touch is the billet clutch cover now fits the quad.....
    Sweet!
