dual discs is it worth it??

good looking Z1 bob love them wire wheels ! :woohoo: im thinking about 17s for my next project ,lot better tire selection but im just wondering i somebody makes a short front fender that will match the radius of a 17 better but still have the old Z1 look to it!are those tubeless ?ive seen pictures of tubeless wire wheels before that were sealed around spoke nipples but dont have a source for them ,any ideas?good luck,happy wrenching!

Wireman: Nope, those are AVON radial tires on SS-spoked Excel aluminum alloy rims with radial tubes.

Bought a Beasley fiberglass front fender that Mr. Beasley and I thought would work with my 110 mm X 17" front tire. It did not. Got a chrome front fender from Klasmo (though you can get it in the US I later found out). It was a serious chore fitting this front fender but it sure looks good I thought.

Wheel Works will seal wire wheel rims. I called Wheel Works about this, but once you've had this done, you CANNOT retighten the spoke nipples again, so I decided just to use radial tire tubes.

There are a number of things to consider with 17" wheels on the Z1s and KZs. I went with 17" wheels because of the wider radial tire choices.

i never knew they made tubes for radials,i wonder if having wire wheels sealed would keep the spoke nipples from working loose?

I did not get that impression when I talked with Wheel Works, that is, that the spokes/nipples would never need to be re-tightened after sealing. Thus, I used the radial tire tubes.

I put dual disc on my KZ 900.I dont think I really needed to. It stops real nice, and I like the symetrical look of the front end with the dual set up.
I put a set of newer sport bike disc and calipers on my XS 650 just for fun.

Hey Fixer,
I added a dual setup to mine just for the looks, the better braking is probably offset by the heavier unsprung weight. I still like it, seems more visually balanced. those old disks are heavy.
Check it out.

I'm considering dumping my second disc and going with a larger single ventilated disc and 4 piston caliper to increase stopping power and shed some unsprung weight.

What might be cool is to use two full floater EBC rotors and aftermarket calipers, which I believe are both lighter than the OEM rotors (even the 4.5 mm OEM thick ones) and the OEM single-action piston calipers found on the Z1s and KZs. Bet even AP or Brembo double-action single calipers like the ones used in the early 70s Superbikes would work well on the street.

KZCSI - I like the look of the later dual disks where the calipers are on the other side. I have the front end off a 79 LTD on my second KZ900 for that reason plus the fact that the front end was free... The dual disks plus the rear disk do stop better than a single front disk and rear drum. Not all that much but some. I have single disk / rear drum on one of my KZs and the triple disk set up on the other.
