As trotts said a givi airflow works great or if you like a small screen an mra.
Luggage I'd buy givi or the like, you can transfer them to your next bike.
Centre stand and crash bars I use Suzuki but I think there's better and cheaper elsewhere.
Hugger helps keep bike and pillion cleaner.
End can, no reason other than looks.
Also use a scottoiler, 23k now on oe chain ( just about done)
