The Flex Forks are made for a heavier unit and what you'll find by placing them on a Sport would be like placing stiff shocks on your truck. They work, they smooth the ride, but work better on a heavier machine.
My new 72" Super Z rides better than I could have ever imagined. The 35 hp Kawi adds weight along with the bigger frame, and the longer wheel base with the added flex forks really smooths things out. I bought the first flex forks that came to my dealer, and I also bought the first flex seat as well. I still run my 2006 Super Z, well my wife does, but the new heavier mower rides better than my older machine. The weight and longer wheel base is what I believe makes the most difference.
