18x14mm High Performance Polygon Variator Sliders, Racing Sliding Roller Weights 152QMI 157QMJ GY6 125cc 150cc Scooter Moped ATV (10 Gram)

Used these to fine tune a 150cc gy6 scooter. Easy to put in. Make sure you watch a video on YT to get the orientation correct or they flat out not going to work. Lots better take off. Will buy again!

Making a little noise, but that should subside. Vastly improved acceleration. Went from 12 to 11 grams. Solid midrange power band. RPMs will be a little higher. Good as any.

Works great! Had for about 2500 miles so far no problems

As described definitely would be great to of had installation instructions. I’ve yet to install still trying to find references how to

Love these...regular rollers get eaten up in my scooter in less than a month..not these...almost 4 months on longest pair and ended up replacing cause I had everything apart NOT because they showed any wear...a must have for a gy6

They are great quality haven't had issue yet although I haven't opened the pack either 🤫

If you have a 2008 125 Yamaha Vino these will not fit! Not sure about other years or models but these don't fit my moped.

These have been the BEST purchase I have made for my scooter in a long time! My scooter's top speed was around 57 to 58 mph with okay acceleration, and then I installed a big bore kit which increased my torque like crazy, but my top speed didn't increase at all, so I was a little disappointed, but knew there were a few more changes I could make. I bought some different roller weights with a little increase to acceleration but still not much top speed increase. I bought a few different weights of these Glixal sliders so I could figure out which weight works best for my bike because sliders aren't a direct equivalence to rollers by weight. I started with the 14g and when that did not meet my expectations, I increased to the 15 gram sliders. When I put these in, the first few runs were an instant change! Then on my way to work I got on the highway and hit my old top speed (58 mph) going uphill! Downhill I got up to 64 mph!! I was so excited! I was able to consistently hit 60/61 mph pretty easily on a straight road, getting up to 64 whenever I was going downhill. If you're on the fence about these, just do it! They're affordable and the gains you will get once you find the proper weight are insane and DEFINITELY worth it! If you are going from Rollers to Sliders, go up about a half gram and that should be good. (My peak power was found with 14.5g rollers vs 15g sliders). Sliders will give you way more acceleration and top speed than rollers, though! The correct installation will be with the Glixal logo & gram facing up in your variator with the highest point of the slider towards the middle of the variator.

Good quality and lasting with no wear.

Not good
