Review: Works on Kymco Agility 50 4T 5mph increase - 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. Review: Can't go wrong - Great product, I've never had no problems with glixal yet. Fits like a glove and good set of weights too ## Features - Variator Outer Diameter:89mm - Variator Inner Diameter:20mm - Bush Size: O/D:20MM; I/D:14mm; Length:38mm - Roller Sets Weight: 6.5g - Roller Weight Size: 16x13 mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01F7H60RW | | Best Sellers Rank | #55,357 in Automotive ( See Top 100 in Automotive ) #35 in Powersports Clutches | | Brand | Glixal | | Customer Reviews | 4.4 4.4 out of 5 stars (1,096) | | Date First Available | May 5, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 13 ounces | | Manufacturer | AT MOTOR PARTS | | Manufacturer Part Number | ATKS-041 | | Package Dimensions | 4.92 x 4.8 x 1.61 inches | ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61SdPpbxIeL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/61mhj4Se3kL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/61OTY4NaJNL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/61bEHD2CydL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/61QfZRTDmpL.jpg) ## Questions & Answers **Q: I have 150 scooter with factory motor cant use that part on** A: I have agility 50 **Q: Will this fit a 150cc scooter** A: Yes on 150cc **Q: Will this fit a honda ruckus?** A: This is for the off-brand Japanese scooters, for any brand scooters like Honda, Kawasaki, Yamaha, buy OEM. **Q: Will this product work ony161QMK?** A: The answer it will work on 139qmb but the shaft for a 161qmk is wider than the 139qmb's.

Fits like a glove and good set of weights too ### ⭐⭐⭐⭐ Good variator but... *by J***E on July 4, 2024* 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 ## Frequently Bought Together - 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 - Glixal ATKS-032 139QMB Reinforced 669-18-30 Racing CVT Drive Belt GY6 49cc 50cc ROKETA Baja Tank JMSTAR TAOTAO JONWAY Scooter Moped ATV - Glixal High Performance Racing Clutch Assy with Clutch Bell for GY6 49cc 50cc 139QMA 139QMB Engine Scooter Moped ATV Go-Kart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/31428102-atks-041-high-performance-racing-variator-kit-with-6-5](https://www.desertcart.sg/products/31428102-atks-041-high-performance-racing-variator-kit-with-6-5) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-22*
