So i just picked up a KZ550 that i plan to transform into a cafe bike for riding around college and such. I love the solo seat look with the tank matched hump but would like to have the ability to have someone ride with me. My idea was to make the hump on the back able to flip up and use it as storage for registration and some tools as opposed to the electrical system. What is your guys take on this or does anybody have any other trick ideas for two-up seat?
