    Fastway's on low position will get about an inch lower. A Renazo Racing seat will increase the distance to the pegs another inch or so.

    cheers for that, i edited my question to be a bit more exact....

    i couldnt wait the extended wait time for a renazo, so i went with an XPC, and had them make it as tall as possible, i think its just a bit above 40" seat height. but my problem is when i stand while riding off road.... my bike has ABS so im limited as to how high i can raise the bars, currently they have 2" rox risers, but i need more......

    so, before i get a bracket made up to lower them, im wondering if there is anything out there already made....

    hey all, nice to be here...! I wish I could convert the bike to look x-country/challenge, that is more my style aesthetically speaking.. but here is my x-moto.

    Hi. I'm new to the forum but, having joined many such fora in the past, I have dutifully searched to find the answer to my question before posting it. I figure this thread would be the best place to stash the answer, so can anyone please tell me the dimensions of the front floating axle (part number 36317696636), including the bore measurments for the XChallenge/XCountry? The corresponding ones for the XMoto, which I know are different, are 13.5mm and 19mm.

    Cheers.
    :huh

    (FYI: make sure you take off the air box and put some greas around the rubber grommit on the throtel body, I even pulled the grommet and put sum around the top that seals agains the airbox [found a lot of dust in there as well].)

    The Uni foam filter is the only foam one I know of. You may be able to find it other places than TT. I also use a sheet of Uni foam above it as a prefilter.

    I don't recall as it was just a remnant I had laying around. Probably 3/8" or 10mm.

    More dust leaks! Thanks for the heads up.
    The bike is mostly apart waiting for suspension parts to be returned. I'm almost finished with DESERT SCORPION'S air box mod. I need to make the thumb screws, and find a spring to hold them in place.

    Thanks for the Touratech link. I'll get at least one, and seal the air box properly.

    If it's for manufacturing one, I personally wouldn't make it smaller than 19,97 mm. 0,03 mm play at that diameter in a bearing is max imho

    does anyone know the exact length of the spacer in the centre of the rear wheel hub, between the two bearings?

    both my bearings failed - one catastrophically, destroying; the bush on the left side, the circlip, the dust seal, and taking a few mm (i think) off the spacer.

    i have spare bearings, and managed to get a similar dust seal, but i want to get a new spacer machined first thing monday - i'm in namibia (SW africa) and it will take up to 3 weeks to get a replacement otherwise...

    lastly does anyone know the size of the circlip? seems about 40mm but i don't have anything to measure it accurately enough and the remaining pieces aren't really big enough to get a match.

    thanks in advance.

    Sh*t, just did all the wheel bearings for a friend an hour ago. Saw it too late :cry
    Hope somebody else comes with the ansswers. Good luck

    For the circlip, just find yourself a circlip for the the same size as the appropriate seal. Circlips are normalised for internal hole diameters asfaik
