Dr.Pulley

DR.PULLEY is a manufacturer from Taiwan that manufactures products for transmissions for Scooter and Maxiscooter.

Better known for their SR variator "Rollers", which have a revolutionary design by not being round, made with a nylon polymer with self-lubrication, compatible with the aluminium on the variator and cover.

The friction on the ramp is lessened besides improving the sliding which prevents wearing. Without a doubt, its functionality has been more than proven, offering a better response from the engine and an increase on the top speed, since it allows for a better opening on the variator and longer shelf life.

Besides rollers, DR.PULLEY also offers centrifugal clutches with a patented high-quality spring tension system.
