A closer look at the engine in those patents reveal what could be a supercharger or alternator.
Fortunately there's a lot of space in the engine bay. If power isn't enough, I might go with aftermarket FI.All I know is this 3-cylinder engine desperately needs some form of forced induction to keep power/torque numbers up, especially in line with its rivals like the RZR, Talon and YXZ. Kawasaki almost always match figures of the competition. So i'm going to say Supercharger.
I'm going to be very interested to see what the aftermarket support will be like for the KRX.Fortunately there's a lot of space in the engine bay. If power isn't enough, I might go with aftermarket FI.
