Glixal ATKS-04016 18x14mm High Performance Racing Variator Roller Weights Set 152QMI 157QMJ GY6 125cc 150cc Scooter Moped ATV Go-Kart (8 gram)

Product worked well,great acceleration on my gy6 150cc , would definitely buy again weight seemed to be perfect no weird shakes or noises

Perfect what I needed for my scooter thanks for good product

I installed their variator and 2000rpm clutch kit on my 125cc gy6 Chinese scooter and helped the mid range a little bit but was really struggling uphill (I am in SoCal). I was topping out at 30mph with throttle wide open on steep hills. I added 10 gram rollers and was extremely surprised at the improvement. On those same hills I am now getting to 40mph. Lost 2 or 3 mph on the top end but well worth the trade off. Also way more peppy on flat ground and no longer need to open it all the way up to get tailgaters off my back. Should be a little gentler on the engine. As long as everything lasts, these are great upgrades to get some more out of your gy6.

I used these on a 06 kymco people 150. Stock the scoot had 15 gram rollers. I ordered an 11 gram set. These made the scoot launch at a higher rpm, and hit top speed faster. The most useful gain comes when slowing down to 15-25mph and rolling back on the throttle. It’s as if the scooter shifts down to a lower gear, rpms spike zipping you back up to speed. Stock ( in the same scenario ) it seemed to hang in a higher gear, keeping the rpms down. It would take a much longer time to reach previous speed.Great cash to results ratio!We’ll se how long they last.

I didn't expect such an increase in performance probably because I didn't realize how worn out my old rollers were. I got the 15g rollers because I wanted the top end speed and got what I wanted. I only weigh 130lbs so the bike gets to 55+ mph.

The media could not be loaded. Bueno

says would fit but did not had to shave them down on the sides but worked ok after that prolly will tkae them back out

Just installed and tested these rollers in my completely stock ZN150T-E scooter and the performance increase was very noticeable. The top speed increased probably 8 to 10 mph higher than before, compared with my old worn-out rollers. I'm super pleased.
