My 2022 RR6p. 4 mo, 459mi, 5 crashes (most recent just now).
Stored "Wesr Bikes" Ulock to the rack which offsets the pannier nicely in the appropriate color scheme. This lock works perfectly as a cafe style lock and it's rubberized.
8" Bar extender with a Hirreyis 1800 lumen light bar giving a flat bar look.
2 Corky Urban bar end mirrors (Not shown (very well)).
And some 4mm cable wrap. This stuff is awesome. I even wrapped  the silver fender braces with it. So now...they blend.
Planning on swapping out that ugly, buzzing 7 speed shifter with an under the bar quick shifter.
The UI controller looks like an old CRT television mounted on the bars. If anybody knows of low profile unit or modification, please chime in.
