I have a crf230 and am adding new high bend bars and bar risers because I am a 6ft tall girl!

Do I need to get longer cables?

I am 6’2” and raised my 230 to fit. High enough I found it necessary to add 3” to the kickstand.
I did use higher bars but not risers. However I replaced the forks and trees requiring a ½” spacer over the bearings, which raised the bar mount. I don’t recall any issues with the 230.
I have a 450x with risers and have no issue with them. Just do it and fix it if you need to.

I've added 1.3" bar risers to a 230 without any problems with cable lengths.

I have not changed the bars, so can't help you with that part of the equation.
