Air Bike from the world of Gundam

Mobile Suit Gundam is a long running Japanese animation, featuring over sized fighting robots, which were somewhat treated like WW2 fighter planes or AFVs. The original show which came out in the late 70's ignited injection plastic model boom in Japan. The kits were those robots, fully posable in 1/144 scale. Many little boys got sucked into building model kits because of the show. Some of the kids never got tired of building the model about the animation show. This guy, Mr.Sasaki ,builds a fully scratched air bike model with parts from those various Gundam model kits. According to his personal model building site, he used Tamiya's 1/12 scale Valentino Rossi rider figure. Mr. Sasaki also is a motorcycle rider. Can you tell?
