I do not totally agree with this statement. I believe that weight in some instances can effect a sleds performance, but I believe that it is a brilliant marketing tactic by Poo to illuminate the fact that poo offers the lightest sled out there. I too often fell that guys are stuck on concept of light = better. I for one would rather a sled 40lbs heavier and able to take an awkward drop, or a sturdy hit to the chassis and be able to shrug my shoulders and keep riding rather than have to get towed out of the BC.
The next factor to play on the weight equations is the engine. There is a reason both cat and yami engines are bullet proof.... because they are designed to be. Once again, riding out rather than towed out
I would have to think that the snow weight accumulation vids have more to do marketing fireback than anything
Had Nytro's that were heavy ... they couldn't take any more abuse / hits than the pros .... great motor but the weight & balance (lack) was noticeable and lousy engineering re skid and front end.
Design spiral for most items try to get as light as possible so that everything else can be made comparably smaller ... lighter chassis means less power is required to move and smaller break systems required to stop which in turn allows the chassis to be lightened as the other components become lighter .... yes there is a limit .... and in most cases its cost.
