Very nice looking bike. :) And it\s the first year model. Not many bikes were sold in the fall 1978 as far as I know.
Did someone replace the Z model tail light with a US model light.

Welcome here :D

Your CB looks really good!

Be aware that the (US) CB650's with spoke wheels only have one (larger) front disk. But from the scenery in the background I would consider that two front disks should be appropriate. :wink:

Great looking bike. I would sure like to up grade my US model 79 cb650 to have dual disk. Anybody know if I need a european wheel or will the disk just bolt on to the
stock US wheel. Also how hard would it be to get a right fork leg with the caliaper mounts on them?

Hi Chuck,
although I guess I cannot really help, I try to summarize a bit how the situations looks for me:

The double disks are not just two single disks, thickness is definitively different and diameter probably also. But as you have the comstars, at least the holes for a second disk are available. I remember there were aftermarket second disk and caliper for CB400 and CB750 (and others) where the second caliper was just fixed on the original fork with a special holder. No idea whether one of these could fit a CB650. Be aware that the master cylinder may have to be changed then also.

The European Z-Model had the silver comstars, if you need or want black comstars you need a RC05 front wheel with a different disk diameter than the Z-model. I do not know whether caliper holders are equal, but the RC05 forks are 5cm longer. I would guess you could fix the smaller Z-model disks on black comstars (but then it should probably also just work for yours) and use a Z-model fork and brake. I think the fork bottom part of the Z-model looked a bit different however. In case caliper holders require this, maybe one can disassemble a RC05 fork and just fix the bottom part with the caliper holders on your original fork right side. If you can't use the present caliper holder position with the smaller disk, you may also have to do that for your second fork tube. If caliper piston diameters are equal, you could also keep your original disk and caliper and only modify the right fork side and get another master cylinder (in case piston diameter is different).

Hope this helps a bit to see your options.

The dual disk models had a wider triple clamp also.

I have a comstar front wheel with dual disc, forks that will accomodate two calipers, both from an 83 650 Nighthawk. No calipers, tho. Can you use them?

I like the look.........are the bars the original ones ?.......they look a bit like mine - a tad more sporty than the turned back ones I remember .......but then again, my memory may not be as good as it was when I was a lot younger ........ :oops:
