I am a new rider and own a brand new z500 SE 2025

I want to buy a radiator guard, tank grips, phone holder and maybe an aftermarket exhaust

Should i just buy original guard and grips from kawasaki or can you guys recommend where to look for, what brands are good? What phone holders are good? I keep getting bombarded by quadlock ads

Im in EU if that matters
