Bandit 250, Japanese spec by the looks of it.
I was tempted to duplicate it a while back and this is what I came up with. Frame has been cut about 1.5-2" after the rear joint with all unnecessary tabs removed. Probably a 4 cell A123 battery under the seat cowl. Seat and cowl custom using the original seal pan. Battery box removed. Coolant overflow is custom and sitting above the rear of the motor. Air box removed and running no filters. Rear sets are custom made from 3/8" steel tube or round stock. Stock headers cut down with generic muffler. Aftermarket clip-ons mounted under top clamp. Aftermarket front master and reservoir. Aftermarket speedo or tach. I'd like to think it's a dual gauge, but probably not. 4-5" headlight. Cut down 70s era metal front fender.
I was very tempted to do it, but I cut the tail off of a bandit 400 while I was in Japan and never could get used to the bob-tail look.
