Thanks for that ADV8 ..... and eakins!
It took a while but we got the answer.
I've currently got a Motomaster 320 disc and 4 pot caliper, a Brembo KTM 640 master cylinder, a HEL braided steel line on a 17" road tyre.
We'll see how it goes once it hits the road.

The stock DR650 clutch cable fits up to the RMZ clutch perch and lever also,quality parts and shorter levers unlike the bargain basement DR items.
This picture needs updating as it was before the pressure switch banjo bolt arrived
