ProKennex Ki Q+ 5X Pro Racquet Review

ProKennex has been around since the late 70s and is now promoting themselves more as a “science and design company”, rather than a standard racket manufacturer. They are the only company using Kinetic tech and that is why I was so excited about this ProKennex Ki Q+ 5X Pro Racquet Review.

ProKennex is not a well-known brand on the market, but they have been relevant in tennis racquet history. They launched the ProKennex Destiny racquet in the 90s that later Babolat bought from them and made into the Babolat Pure Drive, one of the most popular tennis racquets of all time. ProKennex then decided to focus on arm-friendly racquets and they some real classics such as the Redondo 98 and 93 in their catalog. Nowadays, they are most famous for their kinetic technology which has micro-bearings moving around inside the racquet as you swing it. This makes the racquet sound like a music instrument (maracas) and takes some getting used to. And it is one of the most noticeable features in this ProKennex Ki Q+ 5X Pro racquet review.

ProKennex Ki Q+ 5X Pro Racquet Review – Specs and tech

ProKennex Ki Q+ 5X Pro Racquet Review

The ProKennex Ki Q+ 5X Pro 310 gram version comes with an extended length of 27.5 inches (69.85 cm) and the following specs.


Head size: 100 sq inches
Weight: 310 grams unstrung / 325 grams strung
Balance: 6 pts HL (32,5 cm) strung
Swingweight: 340
Stiffness (RA): 67 strung, 70 unstrung
Beam: 21.5 mm all over
String pattern: 16/20

As you can see from the swing weight, this racquet packs a punch. Extended racquets offer higher swing weights, which increases stability and power, but makes the racquet more difficult to swing (less maneuverable).


Quad focus technology – Larger kinetic energy chambers to increase vibration dampening/shock reduction and offer greater torsional stability.

The kinetic chambers are located at 10, 2, 8 and 4 o’clock which is supposed to make the racquet feel solid. The kinetic system sounds like sand moving around inside your frame, but it is actually thousands of micro-bearings moving around inside those chambers loading energy as the racquet moves. So when the racquet hits the ball, the bearings move forwards which transfers power and reduces shock.

ProKennex Ki Q+ 5X Pro Racquet Review – Performance and playability

Besides all the interesting tech, the specs also intrigued me with this racquet. Recently I have enjoyed the plow-through of playing with extended racquets. I am not the tallest guy (176 cm / 5.8 feet) so that extra length, especially on serves, is welcome. And I do like hefty swing weights so that is not an issue.  However, extended racquets require some getting used to since the maneuverability is somewhat hampered and you need to make sure to prepare your shots earlier.

When I timed the ball properly, I loved hitting with the ProKennex Ki Q+ 5X Pro. It really blasted the ball to the other side of the court with good power and spin. It really feels a bit like hitting with Babolat Pure Drive Tour Plus (click here to read my review, click the name for the Amazon link), but with better comfort. It really plows the ball with that intoxicating power and the stiffness is not really noticeable thanks to the kinetic system.

Talking about the kinetic system. The sound of the micro bearings moving around inside the frame takes some getting used to. But when you got over the fact that something is moving inside your frame and it doesn’t mean that the racquet is broken – you don’t think about it.

ProKennex Ki Q+ 5X Pro Racquet Review – Summary

The ProKennex Ki Q+ 5X Pro is an excellent racquet for players looking for extra power without sacrificing comfort. I enjoyed this racquet on serves and groundstrokes and if you can handle the swing weight and the sound of “sand” moving around inside your frame, I bet you would do too. The racquet is also very stable on volleys, but I did struggle somewhat on touch shots. Powerful racquets tend to be more difficult to “feel” and I think this is the case also with this ProKennex racquet. But everything else worked really well with this racquet and I won’t hesitate to recommend it to players who can handle the swing weight, like a powerful racquet but don’t want to skimp on comfort.

Wonderful review and text, as always. For me, those interesting bits on the side are truly 5*. “ProKennex Destiny racquet in the 90s that later Babolat bought from them and made into the Babolat Pure Drive” is an immensely interesting sentence, please tell us some more about it, maybe an entire post?

Tennisnerd March 18, 2019 - 16:07

Thanks! Yes, the plan is to delve into it more closely in the “Tennisnerd Guide to Tennis Rackets” which is a book I hope to finish this year 🙂

SHO March 14, 2019 - 12:38

Sorry for the poor English.
Which maker is the shape of the grip similar to?

Tennisnerd March 18, 2019 - 16:06

The ProKennex grip shape is closer to the HEAD rectangular than the rounded Wilson, but kind of in the middle. Hope that helps somewhat.

SHO March 14, 2019 - 15:13

Have you ever used Pro Staff 97 LS (Red / BLACK)?
I have heard that it is similar to H22 when I put and use lead. Please let me know if you have used it

Tennisnerd March 18, 2019 - 16:05

No, not the Red/Black. Only the CV version. My guess is that it is not very similar to H22…

SHO March 18, 2019 - 16:33

Thanks a lot!
Your comment was helpful.
I’m not too tall, so I’m interested in long rackets. I wish I could sell a long racket like Schwartzman’s racket …
Or I am looking for a racket that I can hit with the tip. Do you have any suggestions?

Tennisnerd March 19, 2019 - 15:00

No probs, when you write “hit with the tip” what do you mean?

SHO March 19, 2019 - 16:43

It is a spelling mistake.
I’m sorry I’m not good at English

Hit with the top
(the upper half of the stringbed)

I am looking for a racket that I can hit with the tip.

Give a try to the Pro Kennex Ki Q+Tour Pro (325)2019.
Serious tennis frame 98 head size. or the lighter version the 315.
Players frame , similar to your Dunlop but not so firm.
Precision, power, touch, stability.

Great review, as expected! I really enjoy how you give even the less mainstream brands their much deserved love.
I know that i’m quite late to the party since ProKennex has already released the newest iteration of this model, but I was wondering how would you compare it to its newer counterpart (ProKennex Ki Q+ 5X Pro 305) and also the Prince Textreme Beast Pro 100 LongBody?

Burn July 22, 2021 - 12:19

Hi Thanos,
I´ve not yet tried the ProKennex Ki Q+ 5X Pro 305 but I do own both this version Tennisnerd is demoing and the next version (2020), which is just a paint job makeover and not a newer version. I also own and used to play with the Prince Textreme Beast Pro 100 LongBody. The power of the Beast is just crazy and although I really liked the racket, I had so much trouble to tame it and I have changed my mechanics to keep the ball in play and that led to a terrible tennis elbow which made me change rackets. The ProKennex Ki Q+ 5X Pro 310 is not even near in the power department but you get a much more heavy and penetrating ball if you swing hard. Also it provides much more control although not the same spin level. The ProKennex has a lot more feel and comfort too.
I think you can expect more or less the same of the 305 with a slight loss of power and plow.
