I recently bought a V-Strom 1000 and it's got standard Suzuki panniers and a 50l Givi top box. I recently bought a Givi screen in an attempt to sort the horrendous turbulence I was experiencing. It has made a difference but is by no means brilliant. It would be nice to have factory fitted heated grips but it hasn't got them and I can live without them. I recently bought a replacement seat though the original, in fairness wasn't that bad and is much more grippy than the Sargent. A radiator guard is always a wise purchase and I should really buy one

.
My wife and me have done a few 500 mile plus days on the V-Strom and had a couple of weekends away on it and the panniers and top box were more than enough (we don't camp). If you need more load lugging capability a tank bag would be the obvious next step. Personally I hate them but I do use one on my FJR1300 for European trips.
I hope you enjoy your bike when you get it - buying the Suzuki is the best bike buying thing I've done in years
