Infiniti contracts their outdoorsy accessories like that to Yakima. The Thule ones are of superior quality, and they have a very sturdy feel, with an efficient operation. I'm not a rider I put them together.

With this hitch you can use any class one attachment. I think the EX is limited to an 800lb tongue weight, which is on par the size.
