I put a ZX-6 master on mine. Worlds of improvement. The 650 handlebars don't have a mount for the remote reservoir so I just drilled the handlebar and put a bolt through. But yeah, the reservoir is pointless without a radial master.
My bad, and thanks for the explanation. I will try to post pics later.Some people are confusing a radial master cylinder versus any master with a remote fluid reservoir. A radial master cylinder has the piston and cylinder turned 90 degrees compared to a conventional master cylinder. It is a feature that is different than having a separate fluid reservoir. In fact, the MC's on my mountain bike are radial, but do not have remote reservoirs.
