Here is your answer for a nice display. They go for around R850 to R900.
I have used them before on the quad bikes, and I see they make a unit specifically for the DR650.

I myself ride a XT660R and I love the bike. Itâ??s not as fast as a 1000cc BMW or the big KTM's, bit hell the parts are cheap, tyres last me ease 12 000 Km's plus, I service it every 8000 km/s, I can cruse 160 easy if needed, the bike is fuel injected, water cooled and runs just fine. Why need a big old clunk of metal, thatâ??s heavier, uses more fuel and all the rest.
They can keep their big bikes, a 650cc is more than fine for me.
