King cat always had the drop and roll.
17 winder did not.
Clutches.........
And Paint.
Some will tell you wiring/fit and finish. But I couldn't tell you the difference.

In 2017, the King Cat has the drop & roll, narrow boards and cowl intake - the Sidewinder got those items in 2019. Hood plastics, windshield, clutches, and paint/decals are the only other differences

Weren't the hoods different on the 07, Cat vs Yamaha ? Thought they were.
Nope it appears not, looks the same.

As every body has already mentioned.
But i have to add the biggest thing to think about if your shopping are the running boards. IMO most important difference between model year and definitely a handling issue over the other things mentioned.
Everyone i now know riding a Sidewinder/Kingcat have now replaced their running boards to CR boards, the Cat design boards are ok if your of a smaller stature with 9-10 size feet. But if your a bigger guy and have bigger feet the Cat boards really suck, they flex and don't give you the footing you really need to rock this beast.
CR boards are wider then the 17 model so wider then all model years but they are rigid and make you the rider part of the sled so they inspire confidence while your ripping the beast.
So something to think about, running boards are up with lightweight pipes when it comes to up grades on these. IMO best mod to do and almost a must.

I believe they are a bit different, as the aftermarket intake from EVO for the sidewinder fits a bit tighter to the hood on the King Cat. The nose grille attaches the same way, but different styling. Would be interesting to put them side by side and compare.

Ok, i have looked at them side by side in 2017 when i bought mine but i just don't remember, thought they were slightly different just don't remember.
Vernon motor sport here in Vernon is our Yamaha/Arctic Cat dealer and they had both on the floor.

The hood on the king cats is what I meant. They fit tighter to the chassis.

As the season is starting guy's and your getting your sled's ready and serviced up, don't forget to service the ROV, it only takes minutes to do it.
Take it off and hose it insides with WD40 then blow it off. Check it by sucking or blowing through it. Its a one way valve so it will blow or suck only in one direction, if it doesn't do that replace it.
Its an easy item to forget as we all came from the 2 smoke world....LOL

This is the ROV, disconnect the 2 hose clamps and undo the torx screw to remove.
It is a spring loaded ball that seats on a smooth surface, what happen's is condensation will collect and so will oil causing the ball to hang up or stick. WD40 will clean it out and not harm anything. Use a low pressure of compressed air and not high pressure not to cause damage. Then check it, you should be able to unseat the ball by your own power, if you can't its no good. If you can also blow air in both direction its no good.
I recommend servicing the ROV several times during the season to keep it operating efficiently.

So i spent a little time looking at the secondary clutch for the Sidewinder and why we are seeing a roller contact issue, what is so different about this clutch?
Well, the roller's only.
I compared it to the Nytro secondary and the design is pretty much the same in everyway except the shoes vs roller's.
Now here is the catch that no one might had noticed before. The Nytro secondary i was working with is used and this is what i noticed, all three shoes are worn uneven. Infact one shoe appears to carry more of the weight then the other 2 shoes, similarly to the Winder rollers.
It is imo the reason this is now an issue is because the new clutch has rollers in it and we are physically checking them (turning them), while with the shoes there was really nothing to check other then wear. The air gap on the shoes or rollers that don't contact is so tight that it is very hard to see thus would go unnoticed generally.
Now is it truly a problem? At first i was thinking yes but now after seeing that the Nytro had the same unnoticed contact issue, No i don't think its a problem. Yes it could be improved.
The shoe wear on a Nytro depend's a lot on how clean you kept the clutch and would run about 1500km before needing replacing on average. I think we are seeing similar numbers from the roller's, maybe a little less possibly. Yamaha did improve their roller's from what i was told so i hope to see improved life out of them.
So why is this happening?
The clutch consist of a 2 part sheave, outer and inner. The outer sheave is solid pressed to a shaft and bolted to the jack shaft. The outer sheave also contains the 3 rollers that are mounted to it.
The inner sheave and helix(cam) are bushing mounted and float on the outer sheave shaft axis. Because it is bushing mounted, there has to be an allowable amount of clearance to prevent seizing, especially when the clutch gets hot.
When you add the torsional load given by the secondary spring, this causes the inner sheave to become ever so slightly untrue with the outer sheave shaft causing the lost of contact at the helix and roller.
In other word's the inner and outer sheaves are no longer square to each other with the spring preload and bushing tolerance given. Its the nature of the beast boys and until something else comes along we will have to live with it.
I have not heard of any performance issues just minor wear issues with the rollers.

What do you think is causing Winder belt breakage?
I have not held a Winder clutch in my hand so I have no experience with them other than two of my buddies ride them.
