Claim:
1. A pulley for transmitting rotational motion between first and second rotating shafts of a continuously variable transmission with a belt, the pulley being fixed to the first rotating shaft, the pulley comprising: first and second parts being traversable closer to or further away from each other, each of the first and second parts mounted onto the first rotating shaft of the continuously variable transmission, each of the first and second parts having a skewed surface which interfaces with the belt and collectively forms a groove, a laser induced friction surface applied to a portion of the skewed surfaces of the first and second parts which engage the belt during operation of the continuously variable transmission, the first and second parts fabricated from a metallic material; and the laser induced friction surface applied solely to the skewed surfaces of the first and second parts.
