Using the stock fenders, does anyone know what the biggest wheel and tire I can fit under the front and rear fender is? This is assuming I'm using alot smaller of a tire of course. I'm "considering" getting custom wheel, I don't want to modify the rear at all, short of zipping off the of the rear of the bolts that are holding the rear fender accents on, I would considering doing a very very light mod to fit a slightly wider/taller wheel, but I'd rather not. Anyone have the numbers on this? Thanks guys

Ideally you want the same rolling circumference to keep the speedo/odometer close to stock.

Here is the formula for figuring your tire's diameter. Take the tread idth,(180)and divide by 25.4. Take that total, and multiply it by the tire height in percentage (0.70). Take that total and multiply by 2. Take that total and add it to wheel diameter(16) = 25.92"

Stock = Rear 25.45 .............. Front.....25.21

180/70/16 = 25.92
200/60/16 = 25.45

180/55/18 = 25.80....................130/60/18 = 24.14
200/55/18 = 26.66....................130/70/18 = 25.17
200/50/18 = 25.87....................120/90/18 = 26.50

I believe the stock front fender will also take a 21" diameter wheel and not look too bad.

You can do a 180 with only a little mod to the rear subframe and brake stay mount; a 200 with more 'drastic' mods.

Thanks for the info doc, very helpful, btw what do you qualify as "major" mods to fit the 200? Are they covered in that article in tech tips? thanks ^^

You'll have to spread the fender subframe. Use a small bottle jack.

You will also have to really grind on the brake stay. Most guys seem to be relocating the brake stay by different means.
