I questioned it as well but everywhere I look, it says the same thing. Its in their
spec sheet. 594 dry. Also quoted in every mag and online vlog/video thats mentioned it. The only way I can think that this adds up is to compare them on paper of course. The 2cyl 998 with a gear driven counter balance shaft (5-8lbs?) is going to be inching close to 3cyl 998 weight while being more compact, the difference will come down to specific design and a few cam lobes and valves. That counter balance shaft is not light as it has to offset the moving forces of that 270/90 firing cycle. (meaning having one less connecting rod/piston is offset by counter balance shaft, and larger pistons, rods). All else being equal and with the displacement being the same, the total weight will be in the ballpark. Compared to its 2s cousins, throw in a chaincase with reverse, liquid cooling, an intercooler, a new airbox, battery and starter, etc on top of the new motor and weight is going to creep up fast. The indy XCR 850 btw is
quoted at 474lbs but that is without electric start, throw in electric start and a battery and it will quickly climb as well, call it in the sub 500lb range but not by a whole lot. It still feels like something is missing here but we only have Polaris specs to go by.
Arctic Cat says 603 lbs dry, and the winder spec (most reliable sources) is somewhere between 587 (video of scale) and 590 (quoted) for which the difference could just be track. Intuitively, all of these sleds are going to be in the same ballpark, its not like we are seeing a lot of steel on one where the other is using carbon fiber. Doo claims 550ish for the machZ, and while I haven't seen any third party testimony, I believe it, they do a very good job of packaging. I did a bottom up evaluation of the machz and came to 558lbs so close..
Ahh, and Mark Lester said that the S4 weighs about 50lbs more than the doo 4strokes so those numbers add up as well. While I take all of Marks hyperbole as such, when he quotes specs they aren't his to make up.
