I like my Versys, I have ridden the Wee strom and like it also. I ride 250 to 400 mile day rides and get along well with it.
I have a 16 tooth front sprocket on the front, which slows the engine down some , and makes a more relaxed ride imo. I can travel at 75 to 80 at 5700 rpm all day, and it is very smooth at that speed. I get 50 to 55 mpg all the time.
Probably can't go wrong with either bike, the Wee is a little larger bike, the Versys is a little more nimble. Both have about the same power, the Wee is a smoother engine as far as buzziness is concerned. I don't have any problem with the small vibes the Versys puts out.
I am assuming you are talking about the 650 strom and not the 1000. I have no experience with the 1000.
If you think the Versys is down on power, you should probably go with a larger bike right from the start. Most of us think the Versys has great power, but if your other bikes are big bikes you might not be satisfied with 62 hp and 40 some pounds of torque.
The stroms have a few quirks, just like any bike, as does the Versys. For whatever it's worth though, I am very happy with the Versys and would certainly recommend it to others.
I have a big windshield, corbin seat, and Trax panniers on mine. I am using distanzia tire on the front, and Tourance on the rear. I does a great job on gravel roads, and handles twisties with the best of them.
+1 on everything you said!
I do quite a bit of "light touring" one up and this bike is comfortable for 200 - 400 mile days. I did 500 miles one day, no big issues with that.
I have a Vario Screen to which I added the stock windshield, this made the V much better for longer days at speed. I also have the corbin seat, 16 tooth front sprocket, a Rapid Transit Recon Tank bag and the Kawasaki (Givi) hard cases. I often cruise at 75 - 85 mph with no problems. I LOVE this bike in the twisties!! Oh, and I have a vista cruise universal installed, which really helps right hand fatique on longer trips, and the Speedy peg lowering kit (I'm 6'2").
I've added many other "farkles", but they don't really add to the light touring capabilities, so no need to list.
I'm on my second set of tires, and about to replace the rear again, the current set are the Bridgestone BTO21's. Already have about 2k more miles on the rear than I got with the stock Dunlop.
I considered replacing the V with a bigger bike, but over time have to admit that the V really is versatile, and cheaper to maintain/operate. I can jump on it to run errands in town, have a lot of fun in the twisties, or go on longer trips, "loaded up". It does it all!!
