Yamaha FX Nytro MTX SE 162
The heavy steel coils in snowmobiles' suspension systems make them tough to maneuver through narrow forest trails. The FX Nytro replaces those coils with nitrogen-filled shock absorbers to reduce weight and enable riders to move smoothly through tight spots and deep snow. A simple bicycle-like pump lets riders adjust pressure in all four shocks depending on their weight and how stiff a ride they want, making the vehicle truly one-size-fits-all.
I don't know how you can overlook the Polaris Rush with it's innovative rising rate rear suspension. It's a fundamental change in snowmobile design. Adjustable shocks have been around for ages. Either Yamaha paid for this or the Pop Sci guys don't ride.
