I also decided to buy hard side bags for the Zx-14. I shopped at TwistedThrottle.com and bought the SW-Motec brand, quick release mounts for the Givi PLX style bags. I also ordered a set of color matched inserts for the hard bags. They are a Kawasaki item intended for use on the '09 Versus with Kawasaki hard bags. The Kawasaki bags are the same as the Givi bags. They are painted the same color as my Candy Lime green, 09, Zx-14.
I still have to order the Givi brand hard bags, but judging by the way the weather is going, I'll have a few weeks before riding season starts.
