    I've heard that changing tires is real diificult on the 950. Any recommended upgrades to ease the process? I've heard of milling the stock rim or replacing with aftermarket rims.
    Also is it needed on front and/or rear, or is one easy enough that no change is necessary.

    The tires on the 950 are no harder to change than any other stuff walled off road tire on any other bike, they are not easy. If you have not done this in the past get someone to show you how and have the correct tools. It is something you should know how it do, and practice will give you the confidence to perform the task in the field, should the need arise.

    Good Luck.

    i think a narrower sun or excel rear is way easier than trying with the stocker

    There are many reasons to change rims, facilitating tire change is low on that list. I've broken bead on 950 rear tire rear tire using the famous kickstand method many times--always solo. It works like a charm.

    "I've heard", or "I've read", are both great, but no replacement for experience. I'd definitely have a go at it before dropping many hundred dollars on a solution YOU may not need.

    I'm in my 100 degree garage, swapping out the TKC's for the Scorps for some road ridin'. As I stand there catching my breath and cleaning the sweat off my glasses, it occurs to me that when the time comes and I do this in the dirt and rocks by the side of the road I'm gonna be risking some damage to the hubs and discs while wrestling with these monsters.

    In the garage I'm kepping the hub ends and discs off the floor with some short pieces of 2x4. Anybody have recommendations for keeping the fragile bits from becoming to dinged up while on the side of the road?

    Btw, the sidestand bead-breaking method works.

    I have a really, really stupid question: how do you put the bike on the sidestand with the rear wheel off? Maybe I'm missing something, but I can't visualize this technique.

    You put the bike on the centerstand first then remove the wheel. Lay the wheel on the ground, deploy sidestand, carefully lean the bike so sidestand breaks the bead (don't forget remove the valve first). Do a search, there is a thread w/ photo's in the Orange Crush forum.

    Got it. Thanks. I've read various references to this technique before but I've never seen an explanation or photo.

    Maybe a smaller diameter inner tube dedicated to the task? Try one an inch smaller than the wheel diameter. A tube will blow up pretty big without a tire around it. That should be enough clearance for the rotors and such.

    Instead of fucking around with the sidestand, it's a tube tire ffs. All you have to do is either ride the bike or walk beside it while in first gear. The bead will break.

    You guys never own dirt bikes before or what?

    nice one fred, you might own a dirt bike but you clearly don't own a 9x0.

    The bead is one mother to break - I've ridden 30 miles fully laden with a flat rear at up to 40mph and it still didn't break the bead, spin the tyre etc etc

    First gear walking beside it eh? I want photos!!!! :rofl

    He may have a point but the speed needs to be up, I did 70 in the wet on the motorway on a flat reat tyre on a 640 and it broke the bead no problem.

    So... Given that it's so damn hard to break the bead on these things, does removing that extra, bead supporting, ridge on the rim make it easier?

    I think going tubeless is the shit for it to be honest.

    i gave two good attempts with mine, but failed both times. or rather - learnt two ways that DONT work. about to give it a try on a third occasion, i bet i get it right this time.

    Maybe I've just been lucky, but I have had 0 problems using the sidestand technique. That is not the hard part of changing a 950 tire, in my experience.

    That said, I can absolutely see how milling that safety bead off would facilitate bead breaking. And it doesn't cost you anything but a little time with an angle grinder. There are some good links, as Mouse mentioned. Search "Alabama safety shoes" and I think you'll find it. Pretty funny.

    Even though I lust after a sweet set of Woody's wheels featuring a 18X3.5" rear, I still wouldn't buy a new rim for this purpose alone.

    Make that "Alabama Safety Boots", and it is called Neduro's Tire Changing Class. First rate post. Follow these instructions to the letter, and you will have very positive results. Another bit of advice gleaned from these pages is to budget 3 hours for the tire change (in the field), and you'll be very happy when it only takes 1 1/2.

    That link, Neduro's tire changing class, is only on tire changing. Your on your own for the other info.

    I chucked my rear rim sans tire back on the bike. On the centerstand, in 2nd gear, I easily removed a good portion of the safety bead with just a bastard file, followed up by a smooth file and then progressivley finer sandpaper until I had it mirror smooth. Took about 45 minutes and makes it much easier to get really stiff tires like the 908RR on and of in a jiffy. Still have prob 50% of the bead left. No lube ever needed for on and off tire changing.

    The centerstand method works just fine, I can debead and change the tire in pretty quick order, esp when the black flies are out.:deal Rinding on a flat just to break the bead seems like asking for trouble and just plain lazy. Mill the bead off and ride on. Can't take credit for the technique, read about it here.

    i went to botswana recently and had 3 punctures on a deserted 300km stretch of road. up untill then, my tyre changing ability was limited to mountainbikes (though i recon this was good groundwork). i learned pretty quickly how to do it with 2 tyre levers.
    i didnt find as difficult to do, as much as i found it a pain in the ass.
    tubed tyres suck!
    i used to have a quadbike with tubeless wheels. if you get a flat, you plug it in 45seconds max. a tubed tyre fix takes about 45minutes to 2 hours in the bush.
