Z650 Front discs

[RALPHARAMA]

I am converting a customers bike to twin discs, but whilst he has a pair of calipers he hasn't got a pair of discs. The discs that came with the calipers are too small in diameter (from memory I think they may have been 275mm and he need bigger 'uns!

try kawasakiheaven on ebay they specialise in 650s

The 4 bolt fixing Z650 twin discs as fitted to C1/C2/C3 etc are all 275mm O.D.

The B models with a single brake caliper and usually spoked wheels had a larger disc.

I "think" it was 290mm but do not have a definitive reference to hand that says to confirm.

The larger rotors with 4 bolt fixings were fitted to single disc models

Think the larger Discs were 296mm.

I have a 296mm 4bolt disc here if you're interested

[Charlie]

296mm IS the Z650B and all the other models I listed single disc. You must be running calipers in front of the forks I'd wager. Those are the calipers that go with the larger discs and vice versa

The one on the other side looks like this. Cheers, Ralph
