Wheels.

[gaz66]

I'm running ZZR11 wheels, on my 2000, not much difference in weight from stockers, but they look nice in black powder coat..

!!!Agreed!!!
ZZR11 rims look good in Black, i'd heard they were lighter than stock REX11 rims, but if you've got a pair fitted, you'll know for sure if they're lighter or not...

ZZR11 rims are way heavier than stock Rex ones, that's why mine didn't stay on long.
later ZXR 750 rims are lighter and give you a 5.5" rear, same spoke design as a Rex

Those wheels look great, are they much lighter? Forks look trick too...nice bike!
