New to Harley’s... I have a 2008 Harley Nightster and I’m looking to get some taller handlebars. Are their any sizes that I can get that won’t require changing lines and wiring?

 

Another co-member may chime in with exact bar makes/ models and what was needed for their install.

I replied to ask further info:
How much taller?
1) One inch, perhaps no cable wire mod needed.
2) Six inch?
2) Thirteen inch?
OP, it might help our co-members reply if you post the bars you are interested in.

Anyway, good luck!
