Obviously NOT a composites expert, cause that looks like soemthing ShervinRRR would come up with (OK, I admit, better than ShervinRRR)That vid of the zx10r was his first ride ever. The body work is made to combine the engine mounts and he also has an extra mount at the front of the engine. The alloy underneath is to protect the headers. There is a complete build thread online somewhere. The guy that built it is a suspension expert here in Aus and has an amazing fzr400 with a fireblade engine shoehorned in and top of the range ohlins gas forks and rear shock.
