I would say the Bat has out sold the shark for many reasons. The number one reason is looks, and that is what puts most people in the brand to begin with. The bat is more traditional.
I swore I would never own a shark, it was ugly. Then a Salesman convinced me a Shark is what I wanted, a nice long ride on one.
That is all it took to get me into a CVO Shark. The look has grown on me lots.
The room on the bike, the shark wins for me. The ride in high winds, the shark wins for me. The ride going by 18 wheelers the shark wins for me. Slow speed in parking lots and a nice twisty road the shark wins for me.
