    A while back I acquired a spare rear wheel for my Sherco. The idea of keeping a competition tire fresh and sharp and then having a practice tire/wheel sounded great. Easy enough to throw in the van as a back up too. Well, the Sherco was sold and replaced with a TRS. I discovered that the Sherco wheel would fit the TRS with just a 1mm washer on both sides of the wheel. The most important thing is to get the brake disc to roll free between the brake pads. Now, I am playing with a Montesa and it makes me cry to think that expensive Michelin is going to wear out just practicing. So, on goes the Sherco wheel. This time I need a 3mm washer on the disc side and a 1mm washer on the sprocket side. Now I have a Montesa practice wheel. Just for fun, sized up the TRS wheel to fit the Montesa. I needed to use the TRS wheel spacer on the sprockets side plus 4mm of washers and the stock Montesa wheel spacer plus a 1mm washer on the disc side. You can get 1mm washers and 3mm washers and mix and match. Moral of the story is it is very likely most current trials wheels can be swapped with one another with the help of some washers - they all seem to have a 17mm axle . Sprockets, of course vary so they may have to be swapped but that isn't too hard. Besides saving my good tire, my spare has already saved the day on far away ride for a friend that that had a flat. Grabbed it out of the van, swapped sprockets, and off he went. Here are a few pics.

    I am a bad person, I was hoping this was going to end in that you were unable to swap wheels, so I could buy that spare wheel from you....

    I spot that wheel every time I am over his house. Either on the back of his TRS or sitting in the corner of the garage. I always think, “damn, I need to get a spare wheel.”

    That's good info! Now I wish I had a spare wheel:bow

    If it works on a 4RT it could also work on the 315R, and that bike has an issue, I think, of using an oddball rear sprocket that is hard to find. A modern wheel with no old-style rim sealing band would be a great upgrade.

    My Sherco practice wheel just founds it's way onto a Vertigo. One, 1mm washer between the swing arm and the left wheel spacer was all it took to fit perfectly.

    You need to pack up the various washers into "kits" for each manufacturer. Then, sell them for exorbitant prices....

    Wait, too late. You posted all your R&D info. :bluduh:D

    Good on you for sharing.

    I have thought about having some new bearing spacers turned up so that the washers don’t need to be used.

    :hmmmmm If you swap wheels with a Beta, you can run down your nubs evenly, since it would be backwards!

    The WR450F I worked on and rode had a spare set of wheels. One set with a smaller rear sprocket with trials tires, another geared down with knobby tires. I fit the latter and converted to Tubliss to be able to run the stiff knobbies at lower pressure (7 - 10 psi). Very handy to have two sets of wheels!

    Friday Fun Fact, replacement Beta rear wheel is bare, just rim/ hub/ spokes, replacement Sherco / Scorpa wheel is the whole enchilada, disc, sprocket, even IMG_8763 2.JPG the coveted X11, and priced accordingly ha ha.
