Unlike most road-going vehicles, most UTVs use a continuously variable transmission (CVT). This means there are gears like a standard automatic transmission and no clutch and shifter like a manual transmission car. The CVT is great because it’s a simple design which is ideal for a UTV which is designed to be relatively simple, but there are some downfalls to the CVT system which is where aftermarket clutch kits come into play. But, how do you know what kind of clutch you need? Well, it all depends on your modifications and driving style.
What Does a CVT Clutch do?
The basic idea behind a CVT clutch is to control what RPM the engine and transmission are fully engaged at. Below that certain RPM, the clutch will allow some slippage which will help get your UTV moving off the line. If the clutch was fully engaged at low speed, the engine would end up bogging down and struggling to push the vehicle. The problem is, the clutch is designed around a specific tire size and power level. This means your power adding mods such as a tune, intake, and exhaust, could be going to waste without proper clutching.
Limitations of the Stock Clutch
The problem with the stock clutch, as mentioned above, is how it’s designed for a one tire size and one power level, plus the clutch needs to be suitable for towing/hauling, mud bogging, trail riding, and dunes. This effectively makes the stock clutch a one size fits all design, making it decent at everything but not good at one particular type of driving.
With an OEM clutch in the mud bogs, your engine can end up bogging down and burning up the clutch. In the dunes, you need the RPMs to stay high, so you have the power to keep the paddles spinning. These are areas where the stock clutch will not keep up with your demands, and an aftermarket clutch kit is needed.
What an Aftermarket UTV Clutch Kit can do for you:
Improved acceleration
Faster shifting and backshifts
Much better throttle response
Improved reliability (especially for modified UTVs)
No more belt issues!
What Kind of Clutch do you Need?
The aftermarket clutch you need depends solely on tire size, driving style, and power mods. But here’s a brief overview of what style clutching will work best for you:
Mud bogging requires a low of low-end torque to turn those big tires through the thick mud. Without proper clutching, you can end up stuck with your engine revving up but the tires not moving, resulting in a clutch and belt smoke - yikes!
Dune driving requires more top-end power to keep the paddles turning at high speed. Without proper clutching, you will slowly lose speed while climbing a big dune and eventually the wheels will stop moving.
Trail riding requires really good throttle response. When you’re exiting a corner, you want to be able to punch the throttle and have the RPMs jump right up where they need to be.
If you’re still not sure what clutch kit will work best for your UTV, contact our performance specialists by emailing sales@vividracing.com or calling 1-480-966-3040. We can help you find the perfect clutch kit for your UTV regardless of power, tires, and driving style.
I an a snowmobiler not an ATV or UTV rider. Seeing this I took a chance and finally found a SIMPLE explanation of clutch basics where most videos were jumping into more advanced tuning. Thank you!
Glad we could help clarify!
How do I test my clutch spring on cv te
ch clutch. My long bolt ba ked out clutch h quite pulling
This was a very well put together video. I ride snowmobiles mostly, so this info is still relevant. Thank you very much!
"Everything you need to know" was just an AD for... send it to them and they'll do it for a price. 😂
If you're the tuner type, this drive system is pretty fun to tinker with. Snowmobiles have used them for years so there's plenty of different parts available. While it's definitely recommended for beginners to not stray far from the factory settings, once you understand how they work and the power curve of whatever engine they're attached to you can REALLY change the way a machine feels. I mean like radically. I could have a newbie ride a certain machine and then make nothing but clutching changes and not touch the engine and have them ride it again. They will have a hard time believing its the same engine because the machine just doesn't behave in the same way.
On my Canam 570 I put on heavy black water 27” tires to replace the 25” light tires and did not replace the clutch. Still works good on Colorado trails
Lots of our guys run heavy 30s with their 570 pretty decent. Like 60 pound outlaw 2s
It think it would greatly Enhance your tutorial - if the "function of the Helix" was explained in stronger detail. Thanks nice Video.
Thanks for the idea!
thanks for the info. I have a wildcat trail with a speedwerx header pipe and muffler, performance secondary clutch sheaves (with performance spring), primary weights and spring as well. I installed the header and muffler first ( I haven't installed the supplied power commander yet) and tested it with my stock clutch system. I had the performance secondary spring already installed and the wildcat performed awesome! so I next installed the rest of the clutch parts without adding adjusting weights to the new weights and it feels like it is binding at slow take off. I had also lost some of my downhill backshifting ( I had trouble holding it going downhill). I then took emery cloth to the ramps to clean up any machining defects? and added the "medium weight" to the weights and reinstalled. Now my back shifting is almost all gone! WTF am I missing? All of these parts are sold as a performance kit designed to work with each other and now I just want to put my clutch back to stock. I imagine I need to remove the extra weight from the weights first but one thing that I am unsure about is I used the existing shims from the stock clutch and wonder if that needs to be corrected? could I be out of alignment? thanks for your consideration.
Shoot an email over to utv@vividracing . com and our UTV specialist would be happy to assist you with setting up your clutch. I already spoke with him about this issue so he will be checking for your email :)
@@vividracingoffroad I appreciate you!
If someone has the right tools and understands mechanics adjusting these clutch set ups would be do able
I'll be watching for sure. Great job on the video layout
Thank you!
I have a 2023 Massimo T-BOSS 550,,, Clutch slip in,,Removed the cover and had oil on the belt,in all about a cup of oil, the kicker it only 2 weeks old and 20 mile's on it.....and the Clutch is different than what you show on your video
I have a 2013 Arctic cat Wildcat 1000...The previous owner install a racing clutch which jerks when you give it gas, we checked the belt and it is fine but I think the spring set up is to strong which if I understand your video is the reason for the jerk and this is especially noticeable when you go to take off slow be it in reverse or forward. I think I need different springs. The past owner was kind of a rock crawler but I am a Desert Runner most of the time and would like to know I am not hurting the belt and trans. which feels like it now.
Thanks

Alright, I'm stumped on this one. Have a UTV that pops out of gear every so often, not pulling anything just normal driving. Unhooked the shift cable and manually put it in gear and it still does the same thing. When it comes out of gear it makes a clicking noise that's matched to the rpm of the engine, when the engine RPM slows down so does the clicking and it will engage back into gear. Any ideas at what parts I should be looking at replacing??? ANY help is greatly appreciated.
Is it a Polaris lol…
I can get the motor to run, idles ok, but when I try and shift into any gear, it grinds and stalls out. With the motor off, it wont shift other than into the first forward detent, not the second. No change with the new belt I put on. Any suggestions?
I need to know how to release the emergency brake on my 2023 Can-Am Maverick X3 X rs Turbo RR
We are trying the tune yourself method our only problem is we have no idea what does what.. I.e what weight added to what position does what to start with. What specifically does adding/subtracting weight to the heel or tip do?
He has no idea...they just throw stuff together and call it an upgrade
@Jonny appleseed yep 100%
what is the difference between High and Low range on my Teryx4? Is it just less aggressive spring/weight engagement, or is there actually a gear change before the primary OR is the secondary disabled etc??
Great explanation
Thank you! 🙌🏼
I have a 2015 Mahindra impact XTV 750s I need a secondary clutch The two little roller bearings Looks like a plastic PVC pipe Mahindraus tell me I can only get him by buying the whole clutch assembly for 500 the secondary clutch assembly They're two little plastic bearings basically our rollers Do you have any suggestions Thank you
i have a wolverine x2 2023 and i dont like it because the rpm is running to hight so i want to find a way to lowering the rpm otherwise i will sell it for a pioneer 1000
The clutch on my rzr blew my mind. The belt looks similar to my harley. Looks like it has teeth for a sprocket but there is no sprockets? Why is the belt designed that way? Does the gaps allow it to bend easier? I GOTS to know.
I think it's for flexibility when it has to pinch down. if the belt was solid it would be more prone to crack or tear when it pinches together. it could also be for weight saving, cooling properties, or when it grips the sheaves.... I really have no idea thoe I'm just guessing 😂
I have an idea for a kind of quadricycle with two small engines that each drive an axle. It bends in the middle. The idea is redundancy and an easy way to send power to the axles. I'm not sure if any of this will work but I think you could steer it with an old style steering gear from an old non power steering vehicle. It might have enough power to articulate the quad. I'm not sure how to put power to the axles but I imagine something like this clutch could do it. Any ideas?
If each engine is powering each axle, you will need a chain and sprocket mechanism rather than a full-blown transmission.
@@vividracingoffroad Wouldn't it need some kind of clutch on each axle?
@@herbertbell9438 I would look into go kart clutching with a chain and sprocket
I bought a maverick max 1000r xrs used from dealer. Dealer had to put new tires on before sale and they ended up putting oversized tired on it. First trip out I blew the belt apart. 😒 I got a new belt put on and currently breaking it in. Just worried that with the oversized tires that it will break again. What would you recommend? 🤔. Tia
Honda talon have a not strap transmission. The rear suspension is bad designed but no friking snowmobile clutches..
Talon rides like a brick! Worst riding sxs I’ve ever driven. Traded mine for a turbo s and don’t miss it one bit
I want to ask if the pulley shaft to shaft distance matters as far as smooth running is concerned?
Awsome video thanks
Glad you enjoyed it! 🙌🏼🙌🏼
I have a 2020 polaris general xp 1000. It has a stage 1 evo tune with a gilomen clutch kit. I run highway speeds a good bit but also play in the mud. Im hitting 7k rpms @45-50mph. What do you recommend on getting those rpms back down around 5-6k on highway speeds?
I think you need a heavier primary clutch weight
I've got a Cub Cadet Volunteer. The clutch won't disengage all the way until I pull the E-brake, which inturn beginning to kill the engine, thus disengaging the clutch fully allowing me to shift. Any thoughts? Great tutorial BTW. Thanks for posting.
No clue but I know i had my idle too high in my fourwheeler and when i lowered it it stopper
I’ve bought a New Can Am 650. It will do 70mph +, I’m not interested in driving an ATV that fast. I’d like to trade top end for bottom end. I’d also like to keep the same factory engagement. I used to play around a lot with Snow Machines back in the day for more performance at times. If I were to contact say, Dalton would you say they could tell me exactly what I need?

What about a clutch for riding down the road at low Rpm's 🤔
you'd probably want a heavier weight in the primary and probably a helix that eliminates the ebs
@@BR-qg5jd thanks for the information
some workshop in houston Texas
I've seen this guy somewhere on another channel. I can't remember it though
Hi 👋
Nailed it!
Good video
Glad you enjoyed it!
In a nutshell tons of extra shit to break on the trail nooo thanks
The way you drive plays a huge factor in the CVT system. If you are just trail riding, you won't have to worry about anything other than the belt. You can prevent the belt from tearing by avoiding overheating it. Extended lengths of full throttle will burn up your belt VERY fast. If you modulate throttle, prevent the tires from spinning, and allow for belt cool downs you will hardly have an issue with the belt.
Skip the toys! Sell the junk while you can. Buy canning supplies, food. Separate wants from needs.
You speak much too fast.
Good thing you watch this video multiple times
Exceptionally informative and helped me make a decision to get a clutch kit for my PRO XP because we go to the dunes a lot and i want more performance.
this is the info I needed. Canam Ryker needs , and options are non existent for 600 engine. But we gonna change that
Definitely not everything I need to know cause I have so many more questions other like troubleshooting the clutch to know if the issue is in fact the clutch out something else.
change speed to 1.5 talks to slowwww
Hi, just to clarify. I have a cfmoto zforce 1000 and I put larger tires from 27 to 30inch. Larger tires means I should use smaller weights correct? 14grams is standard plus 8 grams for the plastic sliders that hold the weights. I should go to 10 or 12 grams correct?
Use a tighter/stiffer secondary spring
You can lighten your weight up and make it shift out at your peak hp rpm

Hey brother I have a 2016 kymco 450i it has 3000 miles on this machine. The belt is in peices,half is tangled up behind the pully. On the smaller clutch there is some loose round peices about the size of half inch nuts looks like there's 3 or 4 just rattling around, don't know what they are. It looks like a small groove 1/8inch teeth 1/8 apart and 1/8 tall teeth. The other belt is an inch wide,3/8 tall and 1/8 gap between teeth. Why would there be 2 belts? How would I get a new belt on, what's the best way? I need help, this is my first time doing this
Using a different belt.. can afect the secondary clutch ? Polaris shop made a mistake and put an other belt, and the bearing of my secondary clutch got messed up… does it has anything to do with the belt? Thanks
I got a question for anyone that can answer it.. I have a Cub cadet volunteer and when I turn it on it makes some buzzing sound that gets louder as the engine gets more revolutions plus the speedometer is going crazy as I drive it( says 15mph when going about 5mph)
would that be a clutch issue or something else?
I put my 2020 hd8 in gear an it clunks once I take off then runs fine anybody have a idea where to start fixing stuff or is this common this is my first can am single cab just added 28x10x14 sti out an back 2in rubber tires don't know if this is bad got it used with 300 hrs
Polaris, can am, article cat: yes, absolutely you better upgrade.
KRX: you can if you want to, but not really necessary.
How would i know if i needed a clutch…..the atv seems to have plenty of torque however it is almost too responsive…..im not used to driving a side by side and my atv doesnt do that
Question is why use them in a side by side unless they are simply cheaper??
How about 2012 900xp with some 14 inch 29 inch tires
5000rpm at 30 mph sound right for my highlifter 900xp?
Great job!!!
Of course, the best CVT is designed by Yamaha, which uses a wet clutch so your belt is always engaged with the primary sheave and thus no belt burning. They back up this industry-leading design with a 10 year belt warranty.
Kawasaki uses wet clutch as well
@@flight2k5 they call it a centrifugal clutch.
@@danlux4954 it’s a centrifugal wet clutch. Now you know..
I'll stand by that Yamaha ultramatic. And the wet clutch. I went to change an 11 year old belt and it was still within spec. Best cvt design out there. I watched Polaris and can ams smoke belts all the time
Only thing I need is one that’s not 250$
Awesome. Thanks for explaining all that.👍
excellent video. keep it up
Thank you very much!
Kinda ya
What causes the pop sound when you hit the gas? Only when stopped and you go. 🤔
It is possible that the popping noise you are hearing is a result of worn out rollers or weights.
My brand new 2021 turbo had that popping you were talking about from factory, I upgraded to the aftermarket assassins s3 clutch with hi load hilux and it seems to eliminate that popping
Thats a pretty good explanation...good job.
Thank you so much!
And this is one reason I chose a Honda pioneer, an I’m more then happy with it.
