650 Matryx RMK

[flying frenchman]

What's your thoughts?
If your an 800 rider will this sled be a good replacement power wise with 138 hp? Runs on 87 octane and fuel efficient so I could drive the piss out of it more.
Clutches should last a long time since it won't vibrate as much as the 850.
My plans if it's a go is a 650 Matryx and do a 163 or 165 with it.

I was hoping for a 650/155/2.6 Khaos...

Rarely are they more fuel efficient.

It takes a given fuel consumption to make the HP needed to move the sled as fast as you would like. You'll likely just use more throttle on a 650 and burn just as much fuel, until you hit wide open where you'll be left wondering where that extra 40hp went.

After running out of power with an 800 163 in deep snow, a 650 just seems like more struggle. Unless you're only riding spring snow in very low elevation, and then why not just go down to a 146 and gain the benefits of a shorter sled?

I've been wanting to try a 600 for my style of riding for years. Now they came out with the 650 and the reviews (even from SW but snow tech and others have good articles out there too) were all positive. I was going to go that route but I've never got to test ride a 600/650 at elevation and was a little gun shy. It runs the same primary weights as the 800 which should say something.
The main reason I was going to try it was one review said it seemed so much lighter than the 850, albeit in a trail sled.
Will it hold you back? Maybe, I mean it's 200ccs. But by a large margin? I sure don't think so.
If I had the ching for 2 sleds I'd for sure have a 650 146 in the stable.
Clear as mud?
And FWIW. My family member who works at a dealer said they had 2 650s go down this year but haven't had a non-2019 850 go down yet.
My final verdict, Buy it and ride the $hit out of it.

A 650 with a 165” track sounds like a terrible idea. And it’s significantly less power than an 800 or 850.
The 650 has the same crank unlike the 600 that had a lighter crank. I can understand a 650 for a trail burner or spring sled in a 146 or even 155. If you’re a new rider or female the 650 might be good as it’s not as intimidating though learn on. It could have its place, but is no replacement for an 800/850.

Thought it was the same crank but lighter pork chop? Different part numbers.

650 would be a great UP, midwest, tug hill, maine alternative. Everyone who's ridden the 600 RMK at elevation knows the hp and track speed challenges, and there are just some places you can't get up, unless you are a 1%'er. As said above, at elevation, it would likely be pinned much of the time, like riding the 600. Guesses, but likely good ones.

The wife and daughter both ride 2020 RMK PRO 600 155. The 600s are great for lighter less aggressive riders, they weigh about 120 with gear, as they are easier for them to control. We ride in the 5,000 to 8,000 elevation of central Idaho and find the RMK PRO 600 155 to be a great sled. The 600 has no problem spinning the 155 - 2.6" track.

The RMK Khaos Matrix Slash 650 with the 155 2.75" might be a real sweet spot for this coming season.

Don't look for any great fuel savings, the 600s use almost as much fuel as the 850s.

Just my $.02

I don't think you need an 850 to smash all the meadows.
A buddy of mine rides an Axys 600 155
and his other sled is a 660 from Carl's. He seems pretty happy with both. Always says man do these things rip an reliable as hell.
He goes everywhere everyone else in the group goes.
I'm sure the 650 can turn a little 165 track just fine. I'm not into being the king of all sledders by needing an 850 ,climbing all the big stuff ,all I want to do is smash all the terrain in sight. If it's got 138hp that should be enough to make many people happy.
Like we used to say back in the day:
Man that guy just goes everywhere with his big sled, up and over.
Kinda gets boring.
Riding a smaller sled is much more fun as you can do it over and over.
Someone mentioned that 2 650s went down,
I'm sure the 850 isnt the most reliable sled out there.

I’m not doubting that a 650 can spin a 165. I just know a 650 is better suited for a 146 or 155 if you’re going to ride it in mountains or anywhere really. Don’t plan on ever lifting your skis lol!
Oh and a 660 from Carl’s is not in the same discussion as a stock patriot 650.

650 in a 146" (2.6) Slash with a 34" ski stance would probably be so fun!

Polaris now has the premier engine in the 600 class. I'm surprised they are not offering more variations such as a 155 Khaos and Pro RMK Matryx Slash with the new 650. The only way to get Velocity shocks and a 7s display appears to be with the 146" track Khaos. I would like to see those options available on a greater number of models with the 650. I don't think it would require any re-engineering just a matter of using existing options. C'mon Polaris. Quit treating the 650 mountain sleds like a red headed stepchild.

I think the advertised fuel economy improvements of the 650 engine are primarily the result of changing the exhaust valves to computer control. The previous vacuum operated valves on the 600 aren't capable of the precision provided by computer control.

I was close to getting this. Settled on a 155 K 850.

Your 800 163 needs tuned if its running out of power in deep snow.

Reminds me when they started putting 151/156/159 on the 700's & 800's early 2000's. I'm pretty sure that these 600's/650's are putting more hp to the track than the vertical edge/extreme's, summit x's, and mountain max's.

The evo is putting more to the track than the powder specials, trust me I had one and for some reason my father still keeps his!

It runs just fine. Well, until I see a cheap used turbo kit, then I second guess myself.

8-10000 feet and chest deep powder was slow going on any steep climbs. We were getting 16"+ every day we were at Cooke City this year, it turned every little thing into a playground. I've never held it pinned so often or so long before or since. That's where a 600 would be painful. (also dug the biggest pits I've ever dug, we were 6-10' deep sometimes to hit stable snow pack that would support weight trying to get the damn kids un-stuck).

Where are the pictures? This didn't happen without pictures. c-mon man.

GoPro died earlier in the season, and I don't ever stop to take pictures. Especially not when the snow is above my head.

So any one ride a 650 RMK or everyone too busy riding the 850s.
Should be a lot of fun in the trees since it's got lots of torque. Should be a great zippy sled.
Looks like I'd have a blast in that much snow too with a 650.
With that much snow might as well bring a grain shovel.
