If you rolled up beside me on a Ducati the last thing I would think is Butch! I'm 52 yrs old,been riding since I was 6 seen lots of chicks on bikes olny met 2 or 3 dykesin my intire life that were riding.I think a chick riding her own bike reguardless of what type is pretty hot.
Stop caring what people think, you can waste an entire lifetime doing that. If the bike fits you and you have enough experience and can handle it go ahead buy it. besides what a beautiful contrast a very feminine young lady that rides a duck.
