Glixal ATKS-041 High Performance Racing Variator Kit with 6.5 gram Roller Weights for Chinese Scooter Moped ATV 4-Stroke GY6 50cc 80cc 100cc 139QMB 139QMA Engine Front Clutch

USed on My 2019 Kymco Agility 50, Works perfectly, went from 28-29mph GPS to 34mph Consistently. I've changed the roller with some other weights, but so far the original Kit that this came with has worked perfectly. So 6.5 gram rollers work great. 34mph not bad, but 28-29mph really sucked. Put perhaps 1k miles on it, friends rode it exc. Had no issues at all. Highly recommend. Tried Glixel Dr. Pully clone sliders 7g weights, it only goes 32mph. Still trying to tune for the proper weights but so far these with 6.5g rollers have worked the best.

Way better than stock even though I purchased separate weights for my riding preference. Seems good quality, 350 or so miles in and not a bit of an issue. Would buy again.

Perfect the scooter runs good

Quality products improved my acceleration

Variator has a higher gearing than the stock Tao pony 50 but it seemed geared too high with a loss of low end power especially on hills. I switched back to my stock variator which seems to have more balanced performance thoughout the power range.

Very good. I do doordash on my 50cc so i'm on it all day every day. After a couple months the stock part must have been worn out, because the belts were breaking prematurely. I switched to this and haven't had to change my belt once in 8 months. must be working. I was riding a standard Chinese 50cc

Part works great. Highly recommended, best price I found, awesome seller

Thought my 50cc engine wasn’t performing. Replaced the spark plug and carb. Felt better. Still bogged off the line. Replaced the old variator and rollers with this new one. Wow. Huge difference. No more bogging off the line and up to speed nicely now. The old rollers were sticking I guess and these new rollers move freely. Very happy with this purchase.

Been using this set up for 2 full seasons now without any problems on a geely 50cc scooter. Was a perfect match to the old worn out stock variator. I will buy again if needed. Highly recommend, but do make sure it will work on your scooter. There are so many slight differences between different brand scooters.

Just bought a clapted out Chinese scooter. I wanted faster acceleration. This variator seem better than the OEM one. The thing is I weighted the roller on a scale and the one I received are 8gr not the advertised 6.5gr. since the ones that were there were 5gr. I got not slower accel but definitely less resilience in hill. The variator itself is smooth and progressive and more substantial than the one that came on my Juajei. Just wish they would advertise the real weight.

Très bien

these dont fit 50cc piaggio this one way is too small
