Mag wheel for a Z1

I'm toying with the idea of putting mag wheels on my Z1 and keep the rear drum brake (haven't mounted new tires yet, now is the time to look into it.) Never seen an 18" mag wheel with drum brake for sale, so either they were never made, or maybe they're rarer than hen's teeth (which would mean way out of my budget).  I like the spoked wheels on it now, just curious about options.

TIA

  I did it years ago ,I believe I used a kz650 18 in year. 

Thanks Ronnie.  Now I know they do exist.    

Just remember the 650 drum is a smaller diameter.
They did make 900 drum rear mag wheels in the UK. In fact I went the other way and put 900 drum rear mags on a 650. CMA 900 race mags.

Hi, First pic 74 z1 w/ Lester cast wheels, bought in 76/77, drum brake, second and 3rd, 81 650 with Enkei cast wheels, sourced fro ebay, rear had a 16, but found a 18, looked for about 2 years, from 650 F model, sold in 80 to 83, and I think only in Europe, Lesters are around but very pricey now, hard to find in US, located in Germany (global moto)605 wheel has smaller brake and axle

sorry too many pics checked, and a few typos, happens when your over 70

Here’s one. No brake plate and kinda expensive

Ebay

Thanks, had a feeling they would be kinda high priced.  Nothing wrong with my spoked wheels, I'll put the money towards tires and a header.
