This post is old but I will respond. I too bought a Yamaha Bruin 350.  I was told the same thing about the Kawasaki 360 by the dealer.  He sold Honda, Suzuki, Yamaha, and Kawasaki so he could care less which one I bought.  The Yamaha and Suzuki have a self adjusting belt.  The Honda does not have a belt.  The Yamaha was cheaper so I bought it......
