Maybe it really is a 450 not a 420?

Nah, it's a 400. However next year Yamaha releases a 421cc R4 to one-up Kawasaki in the stupid cc wars.

This is all kinda Yamaha's fault. With the R3, they didn't have the balls to compete with Kawasaki and release a bike of the same cc displacement. Instead they chose to make a 321 to start the cc wars.
