Wilson K Four 105 K Factor Tennis Racquet
The Wilson K Four 105 is an all-new racquet that represents a new pinnacle of balance in a mid plus headsize. The K Four 105 blends power, stability, and maneuverability with enhanced control, thanks to Wilson K Factor technology. Close to a classic 'tweener design, the K Four 105 has a 10.0 oz. strung weight, 105 sq. in. headsize, but with the added stiffness and power of the wider 28mm beam. A solid choice for a player looking for more pace and spin on their shots, with the control of a slightly smaller head.
What is [K] Factor?
At Wilson's global launch of the [K] Factor product line in Las Vegas February 27-March 1, this next-generation technology was unveiled to Wilson dealers from 50 countries around the world.
All [K] Factor racquets utilize Wilson's proprietary next-generation [K]arophite Black structure which adds additional bonds between the SiO2 and graphite molecules on a nanoscopic scale, resulting in more feel and a stronger, more stable racquet. Overall, there are 4 new key [K] Factor technology concepts found in various configurations depending on the [K] Factor model:
[K]arophite Black-an evolution of Wilson nCode technology which utilizes a new structure incorporating additional bonds between the SiO2 and graphite molecules on a nanoscopic scale, resulting in more feel and a stronger, more stable racquet. [K]onnector-2 external wings molded into each side of the hoop to increase dwell time of the ball upon impact, providing greater control and comfort. [K]ontour Yoke-New frame cross-section shape that enhances stiffness at key stress points for improved torsional stability [K]ompact Center-New shortened yoke design that improves handling, maneuverability, and provides additional feel.
