Yeah apples to apples haha poo 174 434 vs doo 165 446 which holds 2 gallons less so add another 13-14 lbs so 25lbs difference with a longer track. A belt drive poo is 40- 50lbs lighter than comparable doo or cat in the same track length if u don't think that's a big difference take your brand loyalty blinders off.
My 45yr old wife doesn't need electric start I'll give props to doo for the no weight penalty of having it but it doesn't work all the time either.
They weighed a 163 850 so, yes, apples to apples. They compared the same sleds. Polaris is lighter. No argument here but you want to take the lighter Polaris and compare apples to oranges and make it sound like a bigger deal than it is.
You don't add anymore weight. They are what they are. If one has more foam in the seat do you add that. Everyone should have added to the older sled because cat had 4 plugs. If they don't have enough gas they will have to pack gas. If you are so bent on it leave your sled 2 gallons short.
I'm just stating a fact on the electric start. Doo might be lighter if poo had electric start.if you don't like it don't buy it. There are a lot of people, including me and my wife, that do. I am also here to tell you that your sled won't go anywhere that mine won't because you don't have electric start. Also my cranky concrete shoulder will like it better. The shot has always worked. Never not worked so if one doesn't work it needs taken in.
