Glixal ATKS-04014 16X13mm High Performance Racing Variator Roller Weights Set 139QMB GY6 50cc - 100cc Scooter Moped ATV (9 gram)

I did notice a difference on top end. Worked good on a supermach 50 scooter. Not sure how long they last yet.

my moped had very little bottom end however it would go 50mph it would take forever and the wind would have to be on your back some days 30 mph tops to much wind. On trails grass topped out at 18 mph. I installed the 5g rollers now i have much more take off and i can drive 45mph even with heavy winds engine is not revving high.

I just want to clarify this, since a lot of people seem confused. Rollers aren't gonna work a miracle. If you have a 50cc scooter, it's gonna feel underpowered no matter what you do. Another thing is that the weight of the rollers counteracts the tension on the clutch springs. If you have stiffer clutch springs, you need heavier rollers for the same performance. If these aren't working for you, it's likely because you chose the wrong weight of roller. It takes a little trial and error. One more thing. If you have 7 gram rollers and 6 gram rollers, you can mix them in the variator to get 6.5.

Originally bought 6g rollers to replace the worn stock rollers, turns out they were too heavy resulting in piddling acceleration, not good for my hometown where there are hills and wind to fight against. Purchased 5g weights, now my power curve is back to what it was with stock, possibly a bit better. My only concern is durability and quality of the product. The first batch was fine after a month or so of intermittent use, but one of my rollers in the second batch came with a slight crack in the outer shell. Doesn't affect performance as of now, but with crankcase friction and heat I'm fairly certain it's going to become a problem down the road. I'm knocking off a star for that. Still, the rollers are fairly cheap and they ship quickly, and one of the few options that doesn't involve buying a complete variator rebuild kit to go with the rollers. Again, if you're looking for a straight swap make sure you purchase the same weight rollers that you have alreaddy. I had to weigh my stock rollers on an electric scale and that lead me to buy the 6g weights which were too heavy (I thought the stock rollers were 6g that had been worn down, turns out they were probably 5.5g and I misjudged). If you want to try to tune your bike for better performance, remember that lighter rollers engage at higher RPM's, this gives you more time in "low gear" for acceleration but a lower top speed in "high gear". Heavier weights engage at lower RPM's which means you will have less power when accelerating, but if you can get it to higher speed you can maintain that speed easier. With the 6g I could get up to 50 mph at the end of a downhill slope but on flat roads it struggled to get to 30. With the 5g I can get to 30 easily but can't really go above 40.

I bought a brand new 2024 Honda Ruckus that stock run 45 mph. It came with 7g roller weights. I replaced the the rollers for 7g Dr Pulley slider and I find out that they are heavier than the rollers so it doesn’t work. Then I ordered 6g of Dr Pulley Slider they work but it take too long to get the top end speed. So I decided to buy 6g roller weight and, wow! It definitely work way better than the slider on the stock variator. Now I have better acceleration without loosing the top end speed. I’m 250lbs 5’8 tall so the roller weighs or Slider depends on your actual weight. Hope this help you all. Thank you

Got myself a 2022 Honda Ruckus and noticed it was lacking low end RPMs, I'm a big rider 6'4 280 lbs so figured I could benefit from lighter weights. Put the 5 gram weights in and the Honda feels like it has a constant power band but does lack a bit on the high end even on longer stretches. I went from 40 to 35-36 mph going from the Stock Honda 7 Gram weights (confirmed on scale) to the 5 gram weights. I'll be ordering 6 gram weights and that should solve it. The 5 grams are good if your a city cruiser they will make your ruckus have a way more constant power band. Remember, depending on your weight and what type of riding you do (flat roads, city, long curvy hilly roads) you will need to experiment with different weights. I do not suggest mix-matching or cross-mixing weights because your Variator will not be opening/closing as smooth and that can cause vibrations or belt issues that aren't fun. You want a smooth ride so just if you got the stock weights buy the 5 & 6 gram packs and see which ones work for you. I will say the 5 gram vs the 7 gram make the honda have constant revvs almost and your take off is way way faster but the speed itself takes a little longer to get there. The 6 gram for my size & style of riding should get me 40 mph again and also add a little bottom end compared to the stock 7 grams.

I bought haven’t installed them yet ; update I have installed them and they really work for hills especially if you’re in the mountains of nc

I noticed my Ruckus seemed sluggish off the line and had more in it when i was full throttle. I gave this brand a shot with the 6g rollers and WOW what a difference. Acceleration, like a new bike, top speed used to be 38 now im hitting 45+
