Yamaha Sidewinder

There are advantages with 4 strokes and there is still a place for the lighter 2 smokers. To do it right a person should have at least one of each.

I cant believe i just spent my entire noon lunch break reading about a sled that probably less than 1% of new snowmobile buyers actually purchase lol

The ProCross chassis was never designed for the Sidewinder motor or for the Zuk 4 stroke that preceded it. It was made for lighter weight 2 smokers. If you look at a 'Winder there is a lot of room between the bottom of the engine and the bellypan. So the heavy weight that is the engine is 6 inches higher than anything 'Doo makes. Pol has their engines right down low also. It makes the weight problem even worse when it sits up as high as it does. Handling could be improved exponentially if there was a purpose built sled made just for the Sidewinder motor. They could also address some of the other problems at the same time. However I am not optimistic this will ever happen. Snobuilder is on the right track. There are advantages with 4 strokes and there is still a place for the lighter 2 smokers. To do it right a person should have at least one of each. So the sport just got a little more expensive. Again.

Agree with all that grub. Design, and built to be together, and in the proper position for a low cg. Not a misfit kit project. Many years back now, Doo developed the "cylinder reed" engine designed precisely so as be able to get the engine as low in the sled as possible. Many at that time said the cylinder reed design would not work well with induction, and exhaust. The CX chassis set up was one of the best conventional chassis built, very low cg. But then came the REV, and still with the cylinder reed. Lower cg makes for better handling ride. The sled racers have made the biggest developments to our having such good rides!
I think your all over that one indy!

I gave my .02 when the SW came out, saying that engine deserved it's own chassis. Cat hasn't listened. Still working on LED lights.

I believe Textron AC will do this. But with their own designed, engineered, and in house produced engines. They appear to be going to modular production platform of multi use.
