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

excellent quality

I’m using this product on a 50cc Benzhou retro Scooter. Reason for not giving 5 stars : those weights have to be installed a certain way, the full plastic side goes towards one side, it is easy to learn it on Youtube but they could add a short note on the package.

Product was as expected

What did I use this product for?2022 Honda Ruckus Stock 7g roller replacement.My riding routes vary. Some are stop and go if I go into downtown and some are long stretches, if I go to the suburbs to visit family and friends. Based on this mixture the review I am giving is very balanced. The elevation of road I ride is also very balanced with lots of uphill, downhill, and flats.What did I like?I did like the shipping time on this item, ordered November 8th and they arrived November 18th. Expected arrival was November 24th.The color of the rollers is visually appealing. Cool 90's style.What did I dislike?Performance:Brand new 0km/0miles with stock 7g rollers I was able to hit 68km/hr | 42.3miles/hr. My friend 6'2 210lbs was able to hit the same speed on his 2022 Honda Ruckus brand new, we purchased the same day.At 4897km | 3043miles with stock 7g rollers I was able to hit 61km/hr | 37.9miles/hr. My acceleration was quite good, however on some hills I desired more consistent powerband so I purchased these rollers at 6g.At 4897km rollers were changed from HONDA to GLIXAL (top speed 63km/hr | 39.1miles/hr).Immediately after replacing my old worn rollers I noticed a substantial power decrease with dead stop acceleration. It felt like there was not enough resistance/weight.After going for a test ride I was disappointed thoroughly. I took my usual routes and compared my speeds on flats, inclines, and declines compared to the stock rollers I had when new and when worn.The stock Honda 7g rollers when new outperformed these rollers in every measure possible, acceleration, flats, downhill, uphill, and top speed.The stock Honda 7g rollers when worn after 4897km | 3043miles outperformed these rollers in every measure possible EXCEPT top speed and downhill.This was also confirmed going for a ride with my friend who had GLIXAL 6g rollers and I having HONDA 7g stock rollers on some long flats, accelerating from a dead stop, downhill, uphill, and top speed run.Final Thoughts:Initially Honda used 9g rollers on the Ruckus when first released in 2002 had a rev limit of 8000rpm.Then Honda switched to 8g rollers on the Ruckus late 2000's and had a rev limit of 8000rpm.Late 2010's Honda changed to 7g rollers on the Ruckus and increased the rev limit to 8900rpm.The majority of feedback I have read on forums regarding the Honda Ruckus and 6g rollers were from posts pre 2010's. It could be the old setup of the Ruckus where these modifications worked best.With the increase in rev limiter by 900rpm it seems the Ruckus is able to handle go a bit faster stock and handle a heavier weigh than 6g (7g stock).ADDING AIR TO MY TIRES (Front 28psi | Rear 33psi ) gave me better acceleration than adding these rollers to my 2022 Honda Ruckus.I would NOT recommend these rollers to anybody riding a 2018+ Honda Ruckus. You are better off getting stock 7g rollers OR 6.5g rollers.*Remember, the worn rollers in the attached pictures were outperforming these rollers in almost every measure. 3km | 1.8miles difference in top speed only attained on a downhill.

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.
