They went with the single because of the weight.

I am wondering what corners Kawi cut to get the Brute Force to weigh only 2 more pounds than the the Prairie 700.

 

Actually, they probably went with a single because single cylinders are torque monsters. This thing is amazing. It should absolutely rip. I just read that the intake valves are 36mm! Dual overhead cams, EFI, looks great. I like it. Good job, Suzuki.
