I'd suggest here in Canada Kawasaki isn't necessarily considered part of the "Big four"
And to clarify im not knocking them...... In my opinion and based on what I see out there, The most popular ****** rockets in Canada are Honda's, Yamaha's, Suzuki's and then a combo of Ducati or BMW.
Generally you'll see Kawasaki ninjas but usually little 250cc and generally it's learners (M1 licenses)
Hell I borrowed a Kawasaki Ninja 250 when I was learning.
