I always tell the horsey crowd when they start going on about horse accidents that they need to take up a safe sport - like racing motorcycles.
At 16 the daughter was BC provincial Dressage champion, and was eventing. later on got kicked in the warm up ring, rode the cross country course, went past me with tears streaming down her face, and I gave her a bad time about her jumping style. Dragged her off the horse, having gone clear and iced the sore ankle. When home several hours later took her to emergency for x rays, now late in the evening, and as we walk down the hallway the doc holds the x rays up to the fluorescent ceiling light and says, wow, that is a very unusual break! Went on to A pony Club. Ended up with a Dressage schoolmaster and still loves the horses to this day!
But enough of this, the bikes are worth what you value them at, whether pleasure or financial, and to each his own!
