This isn't something I'd ever do but because a Street Glide is my second favorite bike, it'd be the faring. I've always liked how their profile looked. But that's all I'd do.

I'd like to have the ability to put the '14-'17 infotainment system into my 2011 Street Glide.

FXRT fairing on my Dyna

Twin disc setup from the roadster on the front of my custom

Wiz

A Heritage Springer front end.
Sadly, not possible.

This^^

I would take a speedo from a victory highball and mount it on my slim really like the speedo mounted to the handle bars like that

I would put the bars from my Heritage Softail on my Ultra Limited.

ABS and cruise control.

I would put the rear end from a Dyna (so I could run without bags) and the dash console from a Heritage (hate the long console on the RK) on my RK Classic.

Yea, I know. Prolly should just bought a Switchback 7 years ago instead of a RK.
