YunShuo Performance 16x13 6 Gram Sliding Roller Weights GY6 50cc Scooter 139QMB

Mixed these will some Dr pulley sliders to get a 5.5g average. The Dr's definitely hold up a little better but they also cost at least twice as much. Guess it depends how often you're ok to pull off the variator. I put about 3000km on the 3 I installed before selling the bike. They still did the job but I recommend that the buyer install the spare set of included.

They'll work like ANY other brand.

These Slider weights are just as good quality as the Dr. Pulley slider weights at a fraction of the cost!

Good part
