I've got an excellent condition black 5.5" rear wheel with all the extra hardware to mount i.e. sprocket carrier and spacer(s).
So if you've been thinking about adding a larger rear wheel to your dual sided swingarm and your bike is 2002 or newer this will be everything you need (except the bigger tire) to do the swap.
I'm looking to get $275 (or very close) plus shipping and if you're anywhere near NYC and can pick up even better.
Either PM or email me
if you're curious/serious.
