425 lbs combined (or as close as she'll let me guess).
Once we're over 10mph, I don't have much problem, but stability is an issue at slow speed. I did fit a set of Works' shocks which are a big improvement
To keep weight transfer constant, I have my wife keep her head in line with her spine and always peek over my inside shoulder in turns. She NEVER looks over my outside shoulder and doesn't lean more than it takes to peek over. This works out great and keeps everything consistent.
