Winter riding bolt on bits for the GS500, recommendations please

Need some input with regard to what winter riding bits I should get for my Suzuki GS500E? It’s an R reg so getting on a bit but in tip-top condition. I’m thinking screen, heated grips and a rack/box combo for storage, possibly some muffs too. If anyone can recommend any particular make I’d much appreciate it.

I’ll be riding all year, covering about 50 miles a day.

Cheers

Craig
