Great product

I've had this system on my (2) 2019 Kymco scooters now for 2 seasons now. Best investment I could have made for the scooters. Had no idea how factory restricted they were. First of all the Speedometers read wrong so took the speed by GPS. The Speedometer said like 34 and the real speed was actual only 29 mph. After replace the front pulley with this kit the Speedometers read like 41 and GPS has the speed at 36-37 mph. I'm happy with the 7 to 8 mph increase. That much gain for this little money...Sweet!! I'm sure I could do some additional tweaking of other things and get up near 40 mph but this was the best improvement I believe could have been added. Highly recommend. Not to difficult to install, but do need some tools and have some experience. I watched some videos and the first one took me maybe a half hour. Second one went faster after I knew what I was doing.

Seems to be quality I do wish it came with the variator shims necessary to get proper fitment but I can't complain to much given its price point. It's just another purchase to be made... you might get away with using your oem bushing or what ever it's called but I still needed a small shim to get full travel of the belt.I do have a quality complaint they painted the inside of the backing plate so you'll wanna sand that down otherwise you'll wear your rollers flat as it breaks down the paint from regular use.Glixal usually doesn't make small mistakes like this it's not a big one and it's easly remedied with some 800 grit. But it is frustrating cuz it's such a silly one lol.The 6.5 gram rollers is a nice touch though I didn't use them as I've put a big bore kit on it and other mods. So it prefers 8 grams weights but for a close to factory gy6 it would be perfect

Installed on my 05 Honda Metro as a cheap upgrade for a bit more speed. Already have a NYC cdi box from previous owner. I'm about 250lbs and I was getting to about 30mph. After installing I noticed better performance immediately and can to almost 35 now which is pretty good for a metro. For 25$ I'm happy but after about 100 miles I have noticed it getting a bit sluggish when accelerating but I'm still getting to 35. Pretty good indicator the roller weights are starting to flatten so I will be upgrading those but the variator itself is holding up so overall it's worth 25$.

Before I put the variator on, I watched videos of how the person's moped would accelerate much faster. I didn't believe my heavy moped would go faster. It most definitely went up to 65cc on an open road. I had to slow down with how fast I was without a helmet haha. Best thing I could've bought for my Chinese moped 💯💯💯🔥

First I must say, the only “performance” aspect of this variator is the roller ramps, that’s the only thing.I’ve been modding all types of CVT scooters and mopeds since I was old enough to ride. 2 stroke and 4 stroke. What I noticed immediately was that the slide bushing on this variator was machined too small for the bore in the variator and had noticeable amounts of “slop”. After 50 miles it’s already garbage. Another thing I immediately noticed is the horrible drivetrain vibrations, from the moment I installed this variator, I felt them at any rpm, and speed. The faster I went the more “rhythmic” and pronounced the vibration became. THIS IS 100% due to poorly measured and machined slide bushing. This is a poorly made part which is weird because usually GLIXAL makes pretty decent stuff.My review matched many others about this variator and honestly I should have listened and bought something else. I will be requesting a refund for this junk product.FACTS:- brand new hi-quality roller weights are already flat spotted after 50 miles.- this variator is already garbage after 50 miles, and honestly it was garbage to begin with.- this variator weighs exactly 300grams without any weights in it, my stock unit weighs 280grams.- the roller ramps are not consistently shaped from one ramp the the next. Which will cause weird variations when variating.DO NOT BUY!!! Save your money and get a name brand like polini or Malossi! This is crap!

So I bought this variation I didn’t need the heavy rollers so I put my own in and then my scooter wouldn’t go very cst then swapped the back plate the boss and the slides over from my old one now runs great then I get home my frame breaker on my scooter haven’t done anymore testing I am getting my frame breaker welded here soon so I can drive it and will probably update my review

Great for Kymco Zx-50's!
