I love this thread. Having owned a Wee from new for 5 years now, many points are spot on. The two biggest problems with the V are the seat (got a Russell) and the Suspension (still working on it.)
If you can't have two bikes, fixing these two problems will leave you with thousands of extra dollars, and reliability to spare.
I ride allot 2 up and pine for a Stilvio, I'm not sure I could get rid of the Wee even then. I have dropped it off road many times, never broke anything and don't really care if I do at this point.
Dump a Stilvio, I would rather not.
