Fac­tory 250 Yamaha rider Tet­suya Harada turned up at the pre-sea­son Jerez tests aboard a tech­ni­cally fas­ci­nat­ing yet bizarre look­ing new YZR. Sport­ing a bul­bous and droopy tail unit, Yamaha claimed the seat's de­sign im­proved both ac­cel­er­a­tion and top speed as well as mak­ing it more dif­fi­cult for fol­low­ing rid­ers to slip­stream. Looks like a mini-hayabusa.
