Ian Pegram, creator of the Burgman 650-based and roofed Genesis 'Safer FF' tries Honda's NM4 Vultus 750 for size. As a tall chap, (well over 6ft) Ian makes the Vultus look quite small. The slot for the ignition key in the side of the seat back can be clearly seen here. Turning the key releases the ratchet which sets the angle of the seat back. It can also be set horizontal to become the passenger seat pad, and can be slid further backwards too, as with a car seat, but not so easily!
There are more than 50 photos of Genesis, including its gradual development through three iterations from 2003 to 2007 and shots of it alongside Quasars, Monotracers, Ecomobiles, standard Burgmen and much else besides, here: http://bikeweb.com/image/tid/18
