Good thread, I also have a 21 and went with RhinoMoto + CRG Lane Splitters. I have a set of Luis Moto bar end mirrors (https://www.luismoto.it/pair-barend-mirrors-svartpilen-vitpilen-p-1821.html) I had imported from Italy before finding out the ones on my 21 were glued in. I'll ship them for $65...
