Another thing I don't understand is how the Viper is not any lighter than a Nytro? As I recall last spring the Viper was supposed to be 20-30 lbs lighter than a Nytro. I think I even remember reading something like that on the Sled Talk Blog. The naked Viper chassis looks so much lighter than the Nytro. The rear skid looks lighter and more simple. The Viper bulkhead is stamped aluminum rather than steel tube like a Nytro, so it should be a lot lighter.
This is disappointing to me. The 6 model year old Ski-doo 1200 is still lighter than a brand new Viper. It is listed at 507 lbs dry for the TNT model on the website.
