The Big 4
Honda, Yamaha, Suzuki, Kawasaki.
I have been reading about these brands since I was a kid. They are great motorcycles and their market share and the loyalty of their customers proves it. I have owned a few of each.
They are great, reliable, well build and boring. I am glad new companies from China, Tiawan and Korea are here to stir things up a little. The next 10 years are gonna be very interesting for the motorcycle industry and more importantly, motorcycle owners.
