Muzzy Raptor replica using the built ZX-9R engine you mentioned. Even though the Raptor had an 850cc engine IIRC and plenty of beans, a big bore ZX-9 would have even more power.
Rather than a Thruxton, how about a '95-96 Speed Triple and prep it like the Speed Triple Cup bikes were done back in the day?
And finally, rather than a Mladin rep from that time frame, how about an '04 ZX-10R race rep like Rog rode back in the day? That gen 1 ZX-10 seems to be forgotten today, but was an absolute monster when it was released.
