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
You should be Ok with the choke cable though !
