Not to my liking either. Price seems a little high based on just the basic picture and description, however if the price includes major componets to mount the bags, say similar to the need for struts for the sissy bars on some, it may be priced reasonably.
If it requires new struts, lights relocation, etc.
It is a hard bag with vinyl-so make it a little more durable.
Seems (based on what little info is given) priced in same range as something similar from Motor Company and others.
Also with the limited amount that they anticipate to sell, the price per unit would be higher, much the same as many motorcycle parts are compared to an automobile where a manufacture may only be making a few 100 or less compared to 10's of thousands.
Still not my style, that is what I put a sissy bar on for, so I can be like Ray.
I guess the bright side is that there is some leather handbags that go for even more than these and some guys will even buy their lady such (not me BTW).
