Sliding Roller Weight 20×12-6, SR2012-6, Yamaha X Max 125
The choices you make,
make you.
Still struggling choosing initial acceleration or higher top end when tuning your vehicle?
Well, why choosing one over the other?
Now you can have both, with Dr.Pulley patented sliding roller weight (SR).
Here we need to talk about something technical.
There are two crucial factors that make a SR work: Dimension and Material.
First, the calculated design makes SR startup with more power, so you get greater acceleration.
And then the design is able to open the variator wider, push the belt out further, and get you to a higher top end speed.
Next, and yet the most important, produce SR with our special formulated material. The key to ensure
– faster movement (low friction coefficient),
– better wear resistant (bearing grade material), and
– more protection to your variator (non-abrasive fiber)
is in your hands.
Now, combine these two magical factors, and we have the sliding roller weight created and handed to you.
In short, the fastest way to improve your vehicle performance is right here.
What are you waiting for?
Remember
Never use any fake SR on the market, as SR won’t work without our premium material.
In the worst case scenario, those fake products not only just don’t work; but most likely, they will scratch your variator badly.
Nobody wants to waste a whole variator set because of using a bad set of rollers. So, don’t try it.
In order to bring you the best result for tuning, we use high-level alloys in our Dr.Pulley SR and RR.
The copper and aluminum alloys we use allow us to provide you a higher accuracy on the weight you choose.

I can’t believe the significant improvement in performance, from idling around to top speed. Gained 10km per hour or more. Shipping to Canada on two separate occasions was three days! So pleased with the shipper and these Dr. Pulley sliders makes me wonder why Yamaha didn’t use these from the factory.

These sliders are top of the products. I am using them in all of my scooters. They last a lot.
The company has a high customer service. Fast shipping.
I recomend buying dr.pulley sliders directly from manufacturer as they offer relaible worldwide shipment. Best regards from Slovenia.
