The Wilson K Five 98 is an all-new racquet that represents a new pinnacle of balance and comfort in a mid plus headsize. The K Five 98 blends power, stability, and enhanced control, thanks to Wilson K Factor technology. Close to a classic 'tweener design, the K Five 98 has a 10.30 oz. strung weight, 98 sq. in. headsize, but with the added stiffness and power of the wider 26mm beam. A solid choice for a player looking for more pace and spin on their shots, with the control of a slightly smaller head and comfort of Wilson Triad technology.

What is [K] Factor?
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.

The Wilson K Four 105 utilizes [K]arophite Black, [K]ompact center, [K]ontour Yoke, Triad, and Double Hole technologies to provide the ultimate in feel, comfort, and [K]ontrol.
