My '14 1000 came with Suzuki:
crash bars. No issues.
taller wind screen- 5'10"- no buffeting. I think your stock screen is different though.
side cases. You don't even notice they are there but I now use Givi outback 37 for longer trips & soft bags for a couple of days.
I added Suzuki:
fog lights. Overpriced but plug into wiring harness so no splices. Purchased with bike and installed at first service. Could have saved $ here.
center stand. Easy install with the spring tool. Easy on/off even when loaded. No clearance issues.
tank bag & ring. Easy on/off for gas. Keeps pockets empty and carries sun glasses, gloves, maps, tire gauge ... junk drawer.
Look at Adventure Tech for Strom specific parts. Front fender raising kit, side stand foot and mirror extenders are the best bang-for-the-buck farkle$ I've spent.
Current ride: 2001 GL1800; Gone away: 5 BMW's, 4 Honda's, 3 Suzuki's

Haven't bought any oem accessories. There too pricey. The ones I've got came with the bike...side panier, hand guards and center stand. For the other acc...skid and crashbar : sw-motech. Oxford heated grip...givi top case...shorty levers
Im hoping my OEM centre stand and crash bars will cross over onto my new XT when it gets here. Also hoping the SW Motech side stand foot will fit with the OEM centre Stand. For some reason Suzuki are saying their side stand foot is not compatable with their centre stand. Ive got Oxford heated grips on both my current bikes and they are awesome, very rare to have them on full as they are too hot, Also like the "Auto shut off" feature if you forget to turn them off. I do like the replacement chain guard that Suzuki have for the 650, rather nice touch but will depend on price. I love the Givi Airflow screen which I have but no sign yet on availability for the new models.
