Yes, odd that.
I've got a victim of the fuel crisis in my shed...a 1974 Kawasaki 750cc three cylinder two-stroke H2-750 Mach IV. It goes like stink, and stinks as it goes...
There's no way in hell this thing could meet increasing emissions and fuel economy targets...if you just cruise along on the highway, it might get 40mpg (which is abysmal for a bike), if you give it some stick, it'll drop to 20mpg...and if you really get up it, it'll drop into nearly single figures...
