KFactor K Six-One Tour 90 Club

[tennisnoob1949]

I have a K90 that weighs in at about 13oz as well, one of the earlier 'Karbon Black' versions. Feels great to hit with and a great on-court training tool as well, it's one of those racquets which compels you to use good mechanics to hit. I'm a little challenged in longer matches though, the 13oz weight makes it difficult to keep up the timing, movement etc.. I'm considering moving to other racquets with around the same swing weight but lower static weight to solve for this!

It's a misconception that heavy rackets with small heads make you use good mechanics. Since those rackets are low-powered, rec players with bad mechanics can swing really fast and not hit the ball out, which is bad for their development.

My comment was mostly directed at how you cannot just 'arm' the ball with a racquet with a swing weight as high as this one, and how about you're compelled to use your core to provide some power. I don't claim to be someone with good mechanics, but for sure my mechanics are worse with lighter racquets.

The K Six One Tour is still the best-feeling racquet I've ever hit with. An all-time classic.

Love my K90s.

I have 3 of them, but suspect 1 of them to be fake.

Agree with your statement, it's a classic..

Ahh, the K-line, reminds me of this video:

Hi guys, I found a used K90 in good shape. The throat says 12.0oz but says 339 grams. Is it a fake or did any of the versions print the "339 grams" instead of "340 grams"? Everything else checks out.

Thanks

The 12/339 is probably the unstrung weight. They print the unstrung specs on the inside.

Thanks for the response. What I meant was that it normally reads 12.0oz and "340 grams" underneath it. This one reads "339 grams" instead.

Huh. That’s pretty interesting. Perhaps a custom? Quality control?

How do y’all not kill your elbow with that stiffness, is it the weight? I don’t get it.

I definitely avoid full poly. Soft poly + synth gut for me.

Stiffness of? The K90? The weight has something to do with it, but I've mentioned it a number of times before that at least all 3 of my K90s play softer than some other "similar" racquets with lower RAs.

To me it is on par in feel with the 93p, and they definitely feel softer than both the Graphene Touch and 360+ Prestige mids, all which I've demo'd.

Now, I've never been one keen on stiff strings so my comparisons are with like string between frames. I tend to gravitate to gut/poly and multi/poly hybrids, never play with full poly beds.

Have a good multi/poly hybrid you can recommend?

There's many good ones depending what you're looking for. Are you a string breaker? If not, best feeling, affordable one for me is Head Velocity with Pros Pro Concept or Black Force.

I like Gamma syn. gut with Silver 7 as well. Pretty soft combo.

I guess I'm sort of a string breaker. I used Head Velocity 16g mains with Tourna Big Hitter Silver 17g and it lasted about 4-5 hours before the mains popped. Felt sweet though.
On the other hand, I normally use Tourna Big Hitter Blue Rough 17g mains with Gosen OG Sheep Micro 16/17g crosses and cut them out after 10 hours cuz its too stretched out and notched at that point.

Do you use the Gamma syn gut in the mains? Never tried that combo.

Has anyone tried Poly Tour Pro on a k90/ak90?

I know the dilemma being a chronic string breaker myself. I go back and forth with setups that give me best feel (multis or syn. gut in the mains w poly crosses, i.e., lowest durability in the 2-6hr range depending on which of each type) and decent durability at reduced feel (poly in mains, multi or syn. gut crosses in the 10-18hr range).

I would then say best overall is nat gut mains / poly crosses. This lasts me the most. I tend to pair the nat gut with a good tension maintenance poly such as Silver 7 or SPPP.

BTW, having grown up playing nothing but syn. gut, there's nothing better feeling to me, other than nat gut, than having Gamma or Prince original synth. gut in the mains, but that setup may last me 1-2 competitive singles sets at most.

Dusted off my K90's and acquired some more. So i'm revitalizing this ancient thread, hahhahahahahahaha.

The version of this frame that came pre-strung with the red W painted on the string bed, is that the Asian version?
