We had our Nytro Black on the snow for the first time today and even though the snow was marginal, (about 2 feet of wet heavy snow) there is a night and day difference between how this sled worked before and after the conversion. The sled actually responds to your input now instead of fighting it or in some cases just doing it own thing and totally disregarding what you want it to do. Kind of like a parent/teenager relationship. For example, you want to go up the hill and the sled just wants to go down, and if you dont do what the sled wants it just rolls over on it side and spits oil out the intake. I think anyone who has ridden a Nytro in stock form knows what I'm talking about. Of course there is more to the Black than just the Skinz front end, but the combination of modifications that goes into a Black are so far proving that a Nytro MTX can be more than a glorified forest road runner or a point and shoot sled if you boost it. Hopefully the weather will improve and we can get some more seat time on this sled soon.
