• SR2519/8



till 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.
