Any thoughts on these reproduction units?
In need of them and thinking it may be easier to just use aftermarket rather than source, buy and rebuild genuine parts?

I have an aftermarket master cylinder on my KZ1000. It works fine. I can't speak for the caliper quality from experience, but I have never had a bad part from Z1 Enterprises and they sell the calipers.

I also have a couple of used MC's and calipers that I've rebuilt. It's not difficult but the MC's sometimes need to be re-sleeved, although I've never had to do one.
