I’m sure they’re both fast, it’s comes down to how jack the bear you are! I’ve seen guys on 600’s smoke 800 guys it’s just skill and balls! There sweet sled for sure! Thanks Levi! Thanks for everything you’ve done for snowmobiling it’s a dying sport unfortunately! When Polaris comes out w a 800 w sweet suspension for 8000.00 snowmobiling will come back! Thanks buddy
Thanks! Snowmobiling has got a double wammy with powersports being down and having a missing winter last season. Once winter gets going and we have some snow like 2 seasons ago, things will be great! ❄️
@@GunGuyMatt 650 XCR still. I'm telling you, the mid-range powerband is VERY linear and its perfect for staying in the sweet spot when exiting corners. Both the Boost and the NA 850 are punchier and the on/off nature of 850's are killer on the top end, but under 70 mph or so, the 650 just performs flawlessly. The Boost is obviously better for the long pulls on the straights.
I have all three ... 850 NA, Boost & 9R. 850 has power even NA as everyone knows, Boost is all top end and it keeps pulling forever, 9R is all bottom end, pulls so quick from zero and amazingly responsive.
Still could go either way on these. The smooth delivery of the turbo would be nice, but more parts that could have issues. Thought the 9R would be my new choice, but not a lock for sure ! See you in New York mid-February !
I wipp add this, the boost, you need to lern how to drive it! Or I should say drive around its lag! First 2 or 3 drive it fell really slow in smaller trails and couldn't get the ski off bumps and lips like my 2018 assault 800. Yeah it was fast but slow in the small trails. Until I figured it out. It's timming, you need to give it gas like a second before what you are use to. Once you figure that it's a blast! I have the 2 inch track and really it's just not any faster then my 800. It just gets there a whole lot faster. My 800 kinda fell on it's facearound 60-70 mph while the boost will keep pulling to 85-92 on it's way to a top speed of around 96-98 if I remember correctly. The 9r will have alot more bottom end but where the boost will shone is in the ease of getting more hp. Your just a pipe and a tune away from 210-225 hp
Thank you for the comparison . I've been debating between the 2 for trail riding both 1 up and 2 up when the wife wants to come and also i want good suspension for that. You made my decision. I'll go for the 2025 Boost dynamix 👍 👌
Levi, I would really love to see a video comparing entry level 650’s (switchback SP and Indy Sp) as I feel like they are almost forgotten models! Would also love to hear your opinions on those entry level sleds as a professional rider. I’m looking at getting a new sled while spending the least amount of money and I imagine there’s a lot of people in the same boat as me!!
I would love to see a video of you riding the north shore with some sweet 509 quality drone shots overlooking Lake Superior and those rolling hills by silver bay. Gordon lightfoot vibes encouraged! 😅
my 024 VR1 850 boost so far is a great all around sled, i was only able to get 500 miles on last season, hope it snows soon to try soome things. our trail conditions for the 1 week were not the greatest
Hey LEVI!!! My Brother, you're so much fun to watch... I love winter, cause you always come back... You're my sled hero... QQQ Levi, does polaris make a sport utility sled??? And could demo it??? Stay cool my brother, Peace from Cabañas Los Peñas Rochive, Creel Chihuahua, Mexico...
Fantastic feedback Levi. Thanks for the in-depth reviews. If you were riding wooded trails for the most part like what we have in the Northeast in Vermont and New Hampshire - in the hands of highly experienced sledders, do you think the likes of the 600 Cross Country or the 650 XCR is the king of the trail for the maintaining the fastest lines of the day with its mid-range powerband and smoother throttle management?
They work really well in the turns and i'd say most people can go as fast or fast through the turns on a 600 /650. There isn't as much power on with 600/650s to get you in trouble is why I believe that to be. the weight is about the same on the 650 to 850 and the 9R is 13 lbs more so if you know how to deliver the power smoothly with the bigger engines, you can go just as fast through the turns on the bigger engine XCRs as you can on a 650 XCR. Cross country has heavier IFS springs so it wont body roll as much as the XCR so that helps.
That weekend in the UP was fantastic man - loving my 24 XCR 850, the 1.6" track was FANTASTIC in the powerlines that week. I'm torn between a XCR 9R or a Assault 9R, I don't play off the trails much but I love the willingness of the Assault to lift the skis. Will the XCR get some of that "fun formula" from the 9R or will the suspension keep that at bay?
the 136 XCR has tipped rails similar to the assault, so if you get a taller lug, it wheelies also. if you move the rear coupling blocks on the XCR you can get the front end to lift more so it feels more like the uncoupled assault. the 9R definitely helps with lifting the skis as well. I put 1.75 lug on my XCR so it is more playful. Lose probably 5 mph on top end, but still goes over 100 which is fast enough in most cases.
What suspension do you have on these two sleds ? And how’d you get the black hoods on that color scheme all the black and grey 25s I’ve seen have grey hoods the black looks much better
Just be mindful of them dumb ditch donkeys lol. (Deer) . They fly across the trails whenever they feel like it. You don't wanna be blasting down the trails when that happens, especially with not much snow. Deeper snow tends to keep them in the woods. Ride safe Levi. Its awesome that you come up here to the Yoop to ride.
I have an assault 9. The best way to describe it is that it’s a very easy to ride sled at half throttle or less. At half throttle or more it is actively trying to hurt and or kill you 😎
Levi, I snowchecked a 23' XC 850 137 with the 1.35 cobra. I also have a 18' Winder with the same basic setup but the difference is the nimble 850 makes is so fun to ride..the winder is a complete beast with no lag but it also runs hot, how are the boost temps ? Enjoy the UP so glad to see you on our trails buddy!!
suspension is the same on both, the boost is a little heavier but you don't notice that in the turns, you notice the 9r quick throttle response in the turn if you aren't smooth with it.
Coming into the corner fast , braking hard , which one pulls so hard outta the corner to the next corner , that you almost dribble a little , and which one drools , according to you ? Flat smooth trails , Queef Wins
In the twisties , down the Powerlines , local Yooper boy who’s down on power , but knows every corner , bump , he’s hard to keep up to ! YOOPERS RULE ! Get yourself a Stormy Kromer Cap , you’ll blend in better , and if you kiss a Yooper Girl ? You better plan on marrying her ! It’s a Law
I’ve never ridden a 500 but would love to try one. Back in the day I was racing cr 80 and there were some 500s in the bigger classes and it sounded like they were running them a gear high, yet the dirt was flying and they were hauling!
@ if the opportunity arises don’t pass it up. A fellow with your skill set would have a blast on an old school big bore. I have a 1976 Husky WR 360 6 speed and it’s still puts a smile on your face how well these old 2 strokes ran..
If you think you need to ride like you have a death wish. Calling it effective is a bit of a stretch lol anyone that rides the way your suppose to can ride any snowmobile they want girl guy kid doesn’t matter. For the guys that say different, probably don’t want to ride with them if you like your life. P.s. probably not a good idea to have people standing on trail your hot dogging on.
Interesting thing to think about - a 1995 RXL 650 121 MSRP was $7499, factor in inflation that would be $15387.77 today. The 2025 650 INDY SP 137 is $14199 which would be "apples to apples" with RXL other than the SP has 137 instead of a 121. Average Egg cost was .92 in 1995, ave cost as of Nov 2024 was 3.65. Inflation is not ideal.
Awesome vid, your living my dream. Snowcross, x games, and riding brand new sleds every year, keep up the good work
Thanks! I appreciate it. I'm living mine too. 🙌🏼
Thanks for the review. Levi. Was just up there yesterday and it was a blast still.
Awesome! Did you see my "First Ride" video from last week? We had a good time while we were there.
The 9r is an amazing sled its like riding a liter bike in the snow

In the hands of a skilled rider, the 600 class is untouchable in the woods.

Boost Dynamix is an incredible sled! when you go back to back with regular shox to Dynamix, it is amazing to feel the difference.

@@apodbielski913 sleds over 20k are a tough sell right now. A 24k++ machine would be even tougher.

I suppose it depends on what you do with them.

Good eye! They are actually the new QS3 Fox Shox for Assaults. Not quite Dynamix cool, but still cool.

How does the 9r compare to the 850?
much snappier. makes the 850 fell sluggish which makes me laugh because it isn't. 9r just revs so quick.
Ugh , this looks like a great sled ... im in a toss up as I can grab a Cat Riot 9000 turbo ATAC EPS at an $8,000 Discount ...
