I used a set of Apex bar risers on my old R1, lots of flexibility on the height and positions.
I did have to get new brake lines, clutch and throttle cables and re-route some of the electrical connections to each handlebar.
Apex 3" Riser Clip-on Set with 7/8" Bar
I wouldn't do it on my 1299.
So while we are all bitching about having the right bike,
My 1299S mostly sees track use only.
For spirited street rides, the Aprilia Tuono V4 does the duty, with the ability to pack for a weekend using a Ventura removable luggage rack.
For slightly longer stuff, the Multistrada handles that.
On a scale in the twisty street stuff,
Panigale 9.5/10
Tuono 8.5/10
Multistrada 7.5/10
All of each provide an amazing amount of fun and ridiculous corning capability, loaded/unloaded on the street.
