First off, this is the regular FX version, not the RTX version.
That aside - the FX Nytro brings to the rider quite simply a marvelous experience, due to how great of a handle "grip" it has, which is always important for those who look to ride quality snowmobiles. I tried out the '06 version (a friend of mine has seven different snowmobiles, and according to his claims, the one I've tried in comparison was the older 2006 edition), and compared to this one, the '06 is simply put to the minor leagues.
I must say that I'm very impressed with the improvement Yamaha has incorporated within their snowmobiles, with the '08 version's quality shining right at the rider, immediately hinting that you'll be in for the ride of your life. Fast, great accelaration speeds, comfort - what more could you ask for? Of course, there's always the more "advanced" types - ex. the RTX - for those who are very much familiar with snowmobiles and collect them on a say, regular basis and want more out of a snowmobile, but especially for the beginner user or even the intermediate, this is quite simply THE gem.
This is the blue-colored Nytro, and I've seen the rest - in my own personal opinion, this blue-colored version by far blows out the rest. But then again, that's just me being biased on blue.
