			====Sarcastic answer for those doing this for cosmetic reasons====

			There isn't really enough clearance in the swing arm for a really big tire to fit, unless you get the wheels professionally done up (see above). That isn't going to stop some people, though. So...

			Buy EX650 front and rear wheels on eBay. Buy brake disks, calipers, master cylinders, lines, and probably a whole host of bushings and carriers. Then you will need about 4-6 hours of mill/lathe time; a welder would also be helpful. You will have to mill the 650 rear wheel to fit inside the swing arm, then mill the swing arm to fit the wheel. After that you will have to reinforce the arm because you just removed a lot of material.

			After fighting with the sprocket carrier and brake for some time, you will now move to the front end. Here you will fight with fitting a much larger wheel than the forks were designed for. The number of bushings that will need to be used will have to be determined as you use them.

			After a while you will realize that you should have just purchased the swingarm and forks from a 650 and mounted them (with the same amount of work) but then you think, "Wait, why would so many engineers put small wheels on small bikes". Then you would actually read [[Do taller/wider tires work better than the stock sizes?\|a little]], and maybe [[About wider tires\| a little more]].

			At this point your bike is in a lot of pieces and you decide to go buy a gixR1636 because you have ridden your 250 for 2 months/200 miles and you got it to "learn on", anyway.

I mounted up a set of EX500 wheels on my race bike. I did it so I could use a 110 front tire up front and another 120 front tire in the back. EX500 wheels are 3" wide in the front and 3.5" wide in the rear. These are exactly the right widths for a 110 and a 120. Worked great.

EX500 wheels won't bolt right up. You can use your stock axles, but that's about it. The spacers are wrong, the sprocket is in the wrong location. Both rotors are in the wrong location. The rotors are a different size, so the calipers are in the wrong location. I have drawings which show what needs to be machined, but the end cost is still exactly what I paid. Yes it's easier to do a second set, but the only part you'd get to skip are the measurements and calcluations and I didn't pay anything for that part since I did it myself. I paid $250 for a set of wheels including rotors (which I didn't need) and hardware: spacers, and cush drive (which I had machined down).

Anyone interested in going to 17" wheels is probably better off getting a set of 16" wheels welded up by Kosman (they are the ones that did the machining work on the EX500 wheels too).

Unless you're going to race it's not worth it. Even if you are going to race, it's still probably not worth it. :-)
