Something interesting on the sidewinder chassis vs my old XR Doo

[ronzx9]

Had both sleds in the garage today getting ready for snow and did some measuring and observing differences in their layouts and here is what I noticed, if anyone cares.

1) I would have bet from looking at the sleds the seating position was higher on the SW, it isn't. They measure the same from foot board to seat top.
2) The handlebar post is 3 inches farther forward on the SW. I measured from the ski spindle to the bar post. I wonder if the difference between the 137 and 129 cat chassis as to where the pivot point vs rider makes a dramatic change in transfer? I wonder if having the rider that much more forward affects the transfer folks complain about? The center mass may be closer to the pivot point on the Cat chassis and that's why the track length makes a big difference?
3) The SW is infinitely easier to access under the hood/engine than the Doo. I had no idea what I was missing. You can reach the spark plugs without total disassembly. Sweet!
3) The center line of the SW's motor is a lot farther forward than the Doo. I measured from the ski spindle to the clutch and it's 3-4" farther forward. The mass appears to be lower also.
4) The main mass of the engine appears to be farther back on the SW even though the crankshaft is farther forward.
5) Weight past the ski center-line is significantly less on the SW. Nothing ahead of the skis but the intercooler. Not so on the Doo. Exhaust, radiator and lots of other stuff hanging out there.
6) The handle bars are higher and so is the body work on the SW.
7) This is huge, you can remove the front shocks in about 15% of the time it takes to remove the Doo shocks. I realize not everyone cares but I like it a lot.
8) The engine revs way quicker to throttle input.
9) Despite the world saying the SW is heavier it is easier to lift the skis vs the doo. I wish I could put a scale under each ski and the track to see what the distribution of the weight actually is.

I was about to sport wood sitting on the SW, can't wait to ride, common snow! I've been blinded to other sleds for too long. This machine is sweet.

Post all that on dootalk and see how it goes. Lol!

Post all that on dootalk and see how it goes. Lol!

Stop causing trouble,again,JOE

I wouldn't do that. Jamie is already doing his best to make all the 850 owners regret buying them. I predicted that last year and I was right. I think the less we post on DT the better but sometimes I can't help myself.

JOE,most Doo dealers i know are almost sold out on 850s .My yamaha dealer sold 0 sidewiners this year and only 2 last year and i bought 1 of them .Both for me are great sleds .Jamie just has a dealer that didn't pdi his sled correct .Happy Holidays .You get your seat ??

I just found out today another one of my buds bought a SideWinder! Cripes they are popping up everywhere around here. I've never seen so many people switching to one model of machine since the old Polaris Indys. Generally its ski doo country around here. I would have never predicted I'd have so many friends on the YamaCat.

Ron, You think your in love just sitting on it, wait till you get to pull the trigger on that thing! You need to get you're list of sleds changed up. If I'm not mistaken you found a LE, and that suspension is going to surprise you out back. The front suspension is even better, you just wait!

The motor back thing is something they have been pushing for a bit with new chassis. Motor is more “centered” on the chassis aswell as closer to center of your feet so center of mass is more centralized. I totally support and agree with those 2 theories. The rest idk. All depends on riding type I suppose. I’m sure all sleds have a list of nit picks that every backyard engineer feels they can do better

What's Jamie pushing now? Rocky mountain king! He's running out of product to peddle. Lol! Sucks.

Stop causing trouble,again,JOE

Sorry bud. No problems.

Lots of 850's around here and SW. My dealer sold 35 Winders last year. Jamie knows what he is doing he does it all the time and I predicted he would do it again this year.

His new Assault. He likes doing it. I told the guys on DT he would come back this year and brag about his next favorite sled and he did.


Sorry bud. No problems.

Ron I'm glad you are liking the new sled. I really was impressed with mine last year and I can't wait to ride it again this year. With all the talk about Cat quality or lack of I think the Winder is put together quite nicely.

Better access? Try adjusting the chain; or changing the chain case oil; or changing the engine oil for that matter. Most will never touch the spark plugs on any four stroke, but the chain needs to be adjusted regularly. And yes I have owned both 900ACE and 1200 Doos and do my own maintenance.

 

[Doc Harley]

The most sophisticated 4stroke turbo to ever Grace the field of honor. Not everything is going to be easy.

That's like comparing a Porsche to Kia......
