I have ridden the Versys but not the Wee.
What are the factors that you all prefer about the Wee over the Versys?
I owned a '09 Wee that unfortunately was involved in an accident and totaled by the insurance company and I am currently riding a '08 Versys so I have experience with both bikes.
The Wee feels slightly heavier and slower handling compared to the Versys but I have lowered the Versys and this made the handling feel slightly sharper.
I had installed a fork brace on the Wee which gave the front end a much better feel. It felt more planted.
The Wee engine feels like it has more touque than the Versys. The Versys motor is more of a rever.
The Wee feels like there is more seating room for me. The Versys is more compact. The Wee is a better tour/sport tour bike because of the ergos.
Stock braking performance feels about the same for both bikes but adding a front brake upgrade to the Wee was a huge improvement over the stock brakes. I plan to upgrade the front brakes on the Versys when the caliper brakets become availavble (SV Racing?).
I never had either bike off road so can't make any comparisons.
I enjoy(ed) riding both bikes. The key is which bike fills your needs/wants/expectations/budget and fits you ergo wise.
