The FZ1 wasn't intended to be an out-and-out sportbike, so gone is the R1's full wrap-around race-inspired bodywork. But the designers at Yamaha didn't go full retro with it either. On went a sleek sporty fairing that left acres of engine and exhaust pipes on show. The all-alloy twin-spar frame on the R1 has been replaced by a steel tube affair that's more in keeping with the style of the 'naked' or 'retro' class that the FZ1's aimed at.
