need a little help

[Nightengale]

i know i have seen a thread on here that talks about putting a 16 inch special rim on a standard, but i cant seem to find it anywhere. i was just wondering if any thing needed to be done to make it work. i thought i read that you would have to modify the drive shaft tube, but not sure if that wasnt just for the wider tire. any help will be greatly appreciated. and the reason that i am switching to the 16 inch is for a wider selection of tires, especially white walls. i havent been able to find one in the 17 inch, and i have been looking since i first got the bike almost two years ago. thanks in advance for the help.

You also need the brackets for the brake caliper and the axle spacers and it will fit.

im sure we can figure it out. when i switched to the 17on the 850 it was a direct swap. someone before used washers as an axle spacer on the 850 so i used the 750's axle spacer on the 850. I dont know if that applies to what your doing. lol. Hell i dont know much. lol.

Here's the difference.... the pic is fuzzy, but you still should be able to tell...



On the left is the Special caliper bracket and spacer, right is the standard. To swap to the 16" from the 17" you need the Special parts. The inner spacer for the Special is .300" thicker, the bracket is different, and you don't use the outer standard spacer.

The reason for the different parts is the Special wheel moves the brake rotor outboard .3" further with different machining.

height

would there be much of a hight difference between the 17 and 16.

One inch, or 1/2" ride height....

[cpmaynard1980]

Here I go with 850 stuff again. lol. It wasn't much but it was noticeable when i switched up.

[cpmaynard1980]

crazy thought but would it be possible to remove/ machine .3 from the 16in wheel to make the current brake setup work?

Swapping to the Special 16" wheel does not change the actual brake caliper or its mounting. Just the bracket Steve showed, and the corresponding spacers.

These are fairly common parts, and not typically broken or damaged so with as many bikes as there are out there broken apart there are plenty of these parts available so the machining would not make much sense...IMHO.

Possible if you have a lathe that will swing something that big in diameter... but you don't want to do that. The reason for the different machining is with the smaller diameter wheel, if they had left the rotor where it was you would have to remove the wheel/brake assembly off the bike to get the caliper off. Bit of a pain if you need to do any brake work (like changing pads... )...

Hi John,
not as much as you'd think; the 16" wheel runs a fatter tire so some of what you lose on the wheel radius you gain on the tire height.

i didnt think that it would much , on my other build i am doing right now it had an 18inch rear and i switched to a 16 and there was a difference but it wasnt as much as i thought.

rim

the rim i am getting is off of a xs850, would it have the same bracket that i need, to make the switch to the 16.

I do not know for sure, if you go to http://www.cmsnl.com/ you can look at parts fishe for pretty much any bike. I use it all the time. You can compare the part number for the XS850 components to the ones for the XS11 and see if they match. Not always going to give you the full story, but it certainly is a good start.

+1, Thanks for the link. Is there any place on the forum that lists all the useful links people have found?
