Dr Pulley Sliding Roller vs Round Roller in variator
Vložit
- čas přidán 7. 10. 2012
- In the video,you'll see the low gear shift of Dr.Pylley's SR is much lower than round roller and the high gear shift of Dr.Pulley's SR is also higher than round roller.
So SR will provide powerful take-off and higher top end.
next video: Why sliding roller is more durable?

Finally understood how it works.
Thank you.
Anyone who thinks round "rollers" actually roll needs to ask themself which surface it rolls on. Because if it's rolling on one side then it's slipping backwards on the other side. The Dr Pulley sliders work better because they are designed to do what they do and the round ones are designed to do something that they don't actually do. The flat spot wear that developes on round "rollers" is proof of that. Whether or not the Dr Pulley design will actually improve the performance of your scooter depends on the weight you use, but they should definitely last longer.
WOW ! Barry you're the first one that understand the movement of RR ,SR so well.
Best explanation I've read. Definitely lasts longer, and acceleration performance depends on the experiment..
@@DrPulley Hi, for Kymco Dt x360, which rollers do you recommend? 2012(8) - 14g? Thanks
The best explanation i've heard on anything.
The flat part isn’t because they don’t roll, it’s because they don’t roll/rotate 360 degrees. Since they only roll back and forth on a side of the roller, that side wears down while the other does not
Explanation and graphics are clear.
Thanks.
Im using it on my race scooter. Its a very smooth operation and holds it rpm well
Thanks for the video 👍👍👍
150cc Gy6 here .. I bought 13 gram Dr Pulley Sliders .. Turns out my stock rollers weighed exactly the same 13 grams on a postal scale .. I did gain 3 mph top speed with the sliders. Everything on my scoot is stock except for the spark plug and the CDI. The RPMs did NOT change at Wide Open Throttle. They stayed the same as it was when the rollers were installed. I know all these gy6 scooters are different and get different results, but mine gained a few mph with 13gm sliders in place of the stock 13gm rollers. Both tests were at about 4 in the morning, no traffic or wind to interfere with the results.
These work great and the speed increase is very noticeable at first ride after the switch is made. THESE ARE THE SHIT!!! If you haven't upgraded, then I suggest you do so as soon as you can.
Thank you...🐝
Na een paar maanden met 28 gr rollen gereden, ik vond het toerental tussen de 60 km. en 80 km te hoog 5500 toeren, heb toen 30 gr besteld
Erin gezet ik ben nu echt tevreden toeren bij 80 km is 4500 toert een stuk rustiger dank aan dr Pulley echte aanrader
Bij bestellen dus eerst overleggen of sportief of touren
Hi, Alex Leier, thanks to your comment. We'd like to inform you Dr.Pulley will have a new SR (black color ) in the name of Black Pearl, its quality is better than previous IVORY color. Next time you can ask the scooter shop near you about this new SR, where're you located ?
where can i get black pearl dr pulley for skuter sym gts 200 16g
Can i get these in uk?
very nice ilustration and explaination
Hi, thanks ,you like it
Thanks.
Nice info sir, but how about gas consumption? Is it more efficient?
i just gone one set, i think i'm the first in Romania to have dr pulley! cant wait to try them :D
Did you like it?
I was thinking of buying your sliders for my Yamaha Majesty 400 2006 model.. it's a bit sluggish of the line. But when I took it apart it already had them. One thing I noticed when taking it apart was that several of them were fitted wrong. I put them all in the right way and first few take of was amazing.. but now it's back to how it was before.. would they ve to worn when this happens?
It depends on how long of the rod, and how deep is the innerlock in the center of the pulley.
donde compraste lo polini y de que peso son??? gracias
link for the variator kit ? is it specially for the symphony st 200i?
Installed on 2020 xmax 250. Stock weights are 17 grams and i installed 17 grams dr pulleys. Its not faster on low speeds and revving 300 rpms higher on top speed. Tested with a different motorcycle before and after. Thinking about installing 18 grams but since its slower with same weights than original rounds its gonna be significantly slower on low speeds and rev the same as high speeds. I cant say its better than originals.. if i install 16 grams its gonna lose more top speed its already revving more with the same weights. If i install 18’s acceleration will drop. Whats your recommendation ? Should put stocks back? Thanks
Comprei o de 18G fiz todo procedimento de correia nova original, 0,5 e 1 mm desbastada, agora a moto só fica boa qd esta fria, esquentou, já era, trava em 80km
I have been using the Dr. Pulley 4.5 gram sliders in my 49cc scooter and, you do get a lower 1st gear and a higher 4th gear and much longer life than stock rollers. With out a doubt, it is not even close.

I have a set in one of my 50cc Yamahas that have close to 15,000 miles on them. They still perform great, and look almost new. I went 20% lighter than the stock rollers. Much better take off and mid range, about 10% more top end.
I just purchased a 2014 zuma 50f--- Is this and a performance ignition coil the best basic mods I can do for faster acceleration?
Polini ħi-speed Variator. The performance ignition coil is a gimmick. Does not work. Get better variator , malossi 70cc kit with the computer to unrestrick the rpm's and youll have a nice 4 stroke hitting 50-55mph depending on how heavy you are . Im 220pounds and reaching 53mph

Hennie Dohmen de mensen waar het 'fout' gaat hebben meestal de gliders lekker ingevet...en dat mag niet.
I remember experimenting with the honda variator who had grease in it... it worked verry smooth and adding thicker grease made it keep the rpm verry well and consistant !!
with dr pulley rollers?
@@ivarellefsenmentz7446 no with regular rollers. Anyway it does not matter if the rollers go higher because in the end the plates will touch and the belt can not go higher. Damn i spend weeks tuning a variator but only now i know you should only keep them in a good shape and if you want more speed just change the gear ratio in the wheel. Because the bigger the vario gets the more friction and wear on the belt. Adding Mallossi grease is also good but does not last long.
@@moekakke How to change gear ratio in a scooter. And does changing gear ratio make the belt last longer? How?
@@adibz959 No what i mean is that you can better keep the variator and belt small. Because you only have 1 pair of rollers and the bigger the difference between the low belt and high belt the less you will be happy with the weight of the rollers because first it wil be to light and then too heavy. Ther should have been some sort of spring system in the variator that adjusts the counterforce for the rollers. Anyway you can buy gears for a scooter. Not for any scooter but there are brands you easely find another gear ratio for...
Does it increases torque??
its only for stock pulley?
Im running my 2014 yamaha zuma 125 with the stock 12g roller weights. If im looking for more botton end take off power which size rollers should i purchase? Somebody told me i should go with 10g rollers. Is that accurate?
Yes
After ~1000 miles since switching on my scoot (2012 Burgman 400) I have to say that I wish I'd done it sooner. Have found no downsides...around-town response is better, highway riding is much more relaxed.
Did you use same weight as original or higher/lower?
I have a 2016 MP3 500 and I'm trying to decide what weight to go with. I'm afraid of going too light and losing top-end.
I definitely don't want to have to rev the piss out of it on the highway. It could sure stand an improvement from standing still to about 25-30 mph though.
I have nmax150 cc, I want to replace the roller of your product. what size of roller weight is suitable for nmax 150 .. thanks
@Andrian A but their claim in this video is that this tool provides both powerful acceleration and increasing top speed solely because of its geometry apart from effect of mass.
Can you tell me which heavy-duty rollers would be ideal for the Yamaha X-Max 400cc scooter is 2018? Now it's 19g 25x15 original. tnx
If you talk about the durability of weight roller,i'll suggest you can try the sliding roller.
is it increased mileage?
For a Hammerhead GTS 150 to be used on fairly steep hills what GRAM Sliders should i use? I'm unsure if heavier sliders/rollers means more torque or if lighter ones mean more torque i assume it would be LIGHTER to increase power to weight ratio but need clarification.
P.S I'm a newb just started doing this research any assistance in improving my knowledge of such things will be appreciated!
I'm sure by now you found out what you need but lighter more torque, heavier you reach top speed quicker...
Carlos Vreal heavier roller wieghts ship faster but not reaching the the top speed quicker , imagine a car you ship it quick to 5th gear with out giving enough rpm on the engine.

Los rodillos malossi de 22g aceleran más rápido que los rodillos bajados de peso a 22g de pulley ,estos últimos eliminan el corte de inyección por bajar las rpm pero no aceleran más rápido

Hello
I have a 2015 Yamaha tmax iron max, I purchased Dr pulley 16g plus sliders will get yamaha dealer to replace stock rollers at 10000km. If anyone else has done this modification did you get good results? Will post again after 500km with my experience.
how's the performance bro??
Have done close to 5000kms now with the dr pulleys. Stonger bottom end rpms basically the same as before slightly more vibration feel through the foot boards strangely enough. In summary pulls harder from lower rpms.
Hi Dr :) do you know the roller size of Yamaha delight 115
115
Une première
Do you need to use the same weight as you do with rollers?
Normally the weight of SR is 0.5 to 1.5 gram lighter than stock round roller for 50 cc to 200 cc scooter.
@@sebian807 thank you
I am not knocking Dr. Pulley however if the correct rollers profile and pulley diameter/taper has been machined and the weights travel from min to max as intended then the items are correctly doing their job. A different ramp profile with appropriate weights would give a different result. If the original manufacturer wanted the original pulley to give a lower gear for take off and a higher top end gear they would have machined it to do that purpose.
Also if you require a certain minimum belt speed to cause the centrifugal clutch to engage (this being at the rear pulley)then lowering your take off gearing may not help you achieve the required rear pulley RPM for clutch engagement at the offered lower speed. All of this however is also affected by the design and springs used in the clutch & I am well aware that Dr. Pulley offers a good range which I assume overcome this obstacle to performance.
My point is with all the correct components you will achieve the desired outcome of the manufacturer. The idea of replacing rollers with sliders as the only thing you do simply changes what the original manufacturer designed into the components for performance etc. I am sure much testing goes into making matched components but myself would not advocate fitting unmatched or untried components together on the hope of a improved power/performance outcome. Also the sliders have a larger contact area and we have all seen the rollers wear flats onto them self, so wear evidence indicates the larger "flat" surface area should provide longer slider life over roller life. (This is just offered to consider when mixing together components of different manufacture.) Evidence indicates Dr. Pulley is a good product when all components used and also correctly matched together.
Guess these will make your vario the replacement part, instead of the rollers
How if it doesn't sliding but rolling inside the pulley?
I don't know if i understand your question very well, normally the movement of SR is only sliding, never rolling. But in some situation such as the movement of variator and V-belt is not in synchronized then there might be a gap existed when throttle is closed and roller is back to bottom position of ramp faster or quicker than variator back movement. At this moment the SR might tilt if the throttle is open again immediately after the throttle is closed.
Hi man. Is the reason why the belt in the variator not riding higher at the top on WOT be because my slider is not heavy enough? I'm using 5g sliders at the momentno my stage6 vario and will still leave about 5-8mm on the sharpie marker. Got 1500rpm contra and 1000rpm clutch on the rear on a 792x16.6 belt. Take off is nice though.
Hi, we're not familiar to stage6 vario and as i know normally the height of V-belt is mainly determined by the shape of variator but the heavier SR did will make V belt go higher but will have defect about the acceleration.

Which is better the oval or the circle?
The oval one or the sliding roller is better than round one in durability, throttle response that means acceleration is better or no lag.
All you guys are under the misconception that the round "rollers" actually roll in operation. You've got a round object sandwiched between 2 flat surfaces. If it rolls on one side it would have to "roll" backwards on the other side. Since this isn't going to happen it ends up just sliding. Which is what Dr Pulley "rollers" do too, but they are specifically designed to do that, whereas round "rollers" aren't, which is why they always develop flat spots. They are both just sliding weights, but the Dr Pulleys are better designed sliding weights. Just because something is round doesn't mean it rolls.
Hi, you're right the round roller is with hydride motion of rolling & sliding in the variator so you can see flat spots on the roller ( czcams.com/video/E5GXRF5zCsU/video.html#t=4.681244 ).
if this dr pulley roller are really good why yamaha or honda kawasaki or suzuki scooter etc.they did not recomend to their motorcyle?comment please?
+Mike Salta Jr At a guess, they might cost an extra three cents per bike, and/or they do not want to pay the patent licensing money!
Also, Dr. Pulley might not have the capacity to for the number that would be required.
hi john f,now im using 5grams racing roller 6pcs,it work jonh accelarate tke off uphill good,also imusing power pipe zero..my suzuki address 110 go faster..try it..remove the stock pipr look for zero pipe.muffler burial stealth it will break you piston promise..burial stealth no good lost some money...
Sorry to reply so late.Since the cost of SR is higher so Yamaha and Honda didn't recommend this kind of SR but for Piaggio Group's GP800, SRV850 they use SR as stock roller since the maxi scooter GP800, SRV850 is worth to use Dr.Pulley SR.

Mau tanya
Klo rumah roller selain gerak maju mundur, apakah dia muter jg gk?
Rol bergerak naik dan turun, tidak ada rotasi, check Dr.Pulley slider in CZcams.
i want to try it but the problem is the price for these in Indonesia are 200- 300% more than that of normal telfon rollers.
Google search it, I got 6.5g and 7g sliders for $10 usd each. Sliders at the end of the day last longer than roller cause it get flat spot quicker.so you might spend more at the end on rollers.
Hi,thanks to your interest in Dr.Pulley Slider, you can find SR in Indonesia at least from three dealers. As you say the price is 200 % higher than normal teflon rollers, i don't the price of teflon roller. As i know there's no pure teflon roller in the CVT market. Mostly someone will add a little teflon powder in the roller . You can get the SR from Ebay too.

I’m reading the comments in here I feel I have to leave mine.
I’ve riding scouters for 20 years and just scooters for everything as I didn’t own a motorbike that I now do.
I’ve done hundreds of thousands of km and never I had a scooter unmodified.
I have tried every company there is for upgrade anything possible.
My last scooter is a Vespa gts300 which has all the Malossi catalog added and goes really well with better 0-80 acceleration than a t-max530 my brother owns and top speed on tacho (which is very ambitious 150km )
What I want to say is that I had Malossi variator in my last Vespa lx150 also modified to 190 and I needed rollers every 3-5000km. Then in my gts I read and decided to try polini as everyone said is better with 9 rollers instead of 6. It was great from performance point of view but again new rollers in very short time and then after 20.000km my mechanic said it needed replacement as it became unsafe to ride with because it became loose. So I opted for the “best” option I could find the j.costa evo 3. Acceleration was better the bike was always ready to take off but after just 1000km 3 of the roller fingers or however they call them completely broke and the rest were in bad shape and the cost to change was very expensive for just 1000km. So my mechanic said let’s try stock variator with dr.pulleys.
I wasn’t very excited but I’m always open in new things so I said I have nothing to loose.
I have at least 95% of the j.costa evo3 performance with a fraction of the price and what about longevity.
32.000 enthusiastic km and they still look as good as new. I actually inspected them today and was sure I’ll have to replace them but no they are good at least for another service. I never ever heard a performance set of rollers lasting that much these sliders do and my mechanic puts them to every scooter that needs replacement with not one complain yet. Actually no one has yet managed to destroy them and asking for replacement. That to me sounds like a winner and I won’t look elsewhere anymore.
That’s my point of view guys and you can learn something if you listen and save a few €€ by not making my mistakes.
Are your Dr. Pulleys the same weight as your stock rollers? Thanks!
That's a lot of experience. Thanks so much for sharing. Will save me lots of $ not chasing rabbits down their holes.
And dr. Pulley rollers with polini variator works? Incresses something?

@@top1mvp no, its effective for my 113cc scooter..
faito xforce not drpulley.. but still identic tho
If we look at how it works, this type of roller does not rotate but moves. That way the friction on the roller surface with a face comp is very large. This will make the roller quickly damaged or perhaps the face comp drive is damaged due to friction. Spread the standard roller which rotates during displacement is safer due to mini friction

Our opinion to the question of " why yamaha or honda kawasaki or suzuki scooter etc. " is the cost of SR is higher than round roller. And actually Italy Piaggio did use SR as stock roller in GP800 of Gilera and SRV850 of Aprilia.

I just install these Dr. Pulley 14g yesterday, a replacement from 15g stock on my Yamaha Majesty. Didn't see much of differences, except RPM are now much higher during cruising (700-1k). Engine run hotter, losing top speed and also degrade accelerating for passing. Removed and put back stock. What a waste of $55.
You probably need to go heavier 15.5g - 16g.
You're a dumbass. Installing lighter weights will result in quicker acceleration but higher RPM at the same speed. Any weight would have done that. You went from stock 15G to a lighter 14. That's not Dr Pulley's fault, that's yours!
Telling the truth helps, even if it’s painful.

Dr. pulley increases your maintenance cost. Sliding friction is more than rolling friction..
Anwar sadath KT on paper, not in the real world
But the round weights don't really roll, as evidenced by the flat spots that wear into round weights.
Err no the sliding friction is irrelevant in this case and has no bearing on fuel economy or maintenance .

Let me explain some shit to you: EVERYTHING can get better.
I have a 50cc derbi, one of the best 50cc's you can get (Also owned by piaggio), but it still goes faster if I port the cylinder and change the gears. So no matter how good a brand is, it can always get better with some tuning and some mods.
SpookySnek Yeah no shit it can but with these kind of mods it cannot get any better. The vario is already well engineered and improvments are sparse on these things.

Does your stock roller weigh the same 15g? I have pcx 150
Light rollers get less speed and stronger. Heavy rollers, higher speed on the road.
For conventional round roller, it's true " Light rollers get less speed and stronger. Heavy rollers, higher speed on the road " but for SR sliding roller, its shape is designed specially to make low gear becomes much lower (much acceleration at initial step) and high gear becomes much higher (higher top-end at high gear) so you can select one suitable weight to get both excellent acceleration and higher top end.
Indonesian language please
No diff

LOOK AT THE ROLLER DEMONSTRATION!!! "Round Roller in high position" and "Sliding Roller in high position" has a different Rollers house shape, so the ROUND ROLLER LOOKS LOWER and a SLIDING ROLLER LOOKS LIFT FURTHER. It's not not fair...... WTF
Are you stupid? Or joking? That's the point of the sliders being better. Same revs, higher lift.
