The pictures in the first post represents (a souped up version of) the Honda VTR (250); the following page is in Japanese but pictures should still be visible:

The engine is very similar to the VT250's but the frame is different -- somehow recalling a Ducati Monster.
I owned the VTR 250 for four years, it is an incredibly cost effective bike: 26 km/l, price new is one of the cheapest 250cc in Japan, 32HP, 150 km/h top speed (enough to have the police take away your license on the spot if they catch you on the motorway), no MOT.
I sold it at 45000 km wihout ever having to fix it once (aside from tires, brake pads, oil etc.).
