If you are a tennis fan (like me), you would understand that to be at the top of your game you need to have a tennis racket that you play your best on. Although it’s not like Roger Federer or Serena Williams when she plays, at least one has to be competitive. This can be achieved when you are equipped with a tennis racket that best suits your needs.
The Wilson K Factor K4 is one of the newest tennis rackets released by Wilson, the world’s leading manufacturer of tennis rackets. The K-series rackets were designed using the Karophite Black construction which gives them a stable feel. K4 is specially designed for players looking for more rhythm and spin in their shots. It has the best combination of power, stability and control. It has unique frame engineering to provide a greater sense of strength and stability while giving you a larger sweet spot in a medium-large head size racket. For top spinners, this racket is very effective in power and control, maintaining a full swing stroke on both forehand and backhand. It has some stiffness in a wider beam that gives the player consistency in each shot. Aside from what it can do, the K4 is an attractive racket with its blue, white and black color scheme.
On the other hand, the disadvantage of this racket for a flat-hitting player who does not normally complete a full swing would result in a constant outside shot at the baseline. For players who are used to a string tension of 55-58, this racket does not work well as it works well with a high string tension of 60-63kg. Like all good tennis rackets, the K4 is quite expensive when it was first introduced to the market. Market price ranges from $200-$250.00 and has limited availability.
This racket was named K4 for its [K]oraphite black structure, [K]center of impact, [K]around and [K]check. All in all, despite some drawbacks in price and availability, the K4 is a racket worth owning if you’re a player who feels the need to improve the stability and power of your game.
