WR521 SEADOO RX/RDI SPONSONS

In testing we discovered that this ski lacked directional stability at speed in choppy water conditions and has a bad tendency to over steer. If you start to turn sharply the OEM sponsons bite and spin the boat into a hard turn that you can't pull out of. The Worx sponsons change that and make this boat a pleasure to ride as you can run as fast as you like with complete control and turn as you hard as you want to again in control.
