yes and no
I dont think I've ever use std bars on a CX
My first CX had bars from a Kawasaki I think which as they were only slightly higher
meant I could use std cables
Higher wider bars means you'll need to use longer throttle and clutch cables
I have pattern customish bars on the mongrel and just buy custom cables
The Custom bikes usually have a long pull back bars and they also have tilted master cylinders
to keep the fluid level so you may want to consider this when selecting your new
7/8 22mm bars.
Also if you have the STD nacelle and wiring and you want to fit high bars
you may struggle to fit the electrical cables/connectors in their usual place
All these things are quite doable but its best to measure and consider whats involved
before starting.
You should be Ok with the choke cable though !
