First, let me state that the RTV900 is a fine machine. Truth is, the RTV1100 shares basically the same platform. Prior to the RTV1100s' introduction, if you wanted a cab, you had to go with an aftermarket bolt-on unit, aftermarket heater etc. A good solution no doubt. However, having driven both models, the cab on the 1100 is superior, as you would expect a factory cab to be. The a/c is an added bonus. Plus, pricewise, it's about the same money as an RTV900 with cab and heat. As a new model, the 1100 is more refined than the 900, again, as it should be. The RTV900 remains a great choice for those who don't want a cab, the extra weight, or the extra size altogether. I look at it this way, each machine shines in it's own way and it sure is great to have a choice.
