In answer to your question, I'm 5' 9" and I weigh in at 12 and a 1/2 stone. I'm pretty fit for my age, and over the past 12 months I've been riding a Daelim Daystar 150 cc - which is a forward-facing low slung cruiser style bike - every day in heavy Singaporean traffic, so I'm getting more and more used to riding at slow speeds and filtering.
