A great competitive advantage in bowling today is modern urethane.  It provides bowlers with control and the ability to play different parts of the lane than reactive resin.  However, because urethane also has clear weaknesses, MOTIV® set out to create the ultimate cover material that harnesses the strengths of traditional urethane, but offers far more versatility. Introducing the Covert Tank. 

The revolutionary Frixion™ cover material MOTIV® developed for the Covert Tank is not urethane nor reactive resin. It is microcell polymer. Traditional urethane is virtually non-absorbing while reactive resin is highly absorbent.  Frixion™ microcell polymer absorbs oil at a fraction of the speed of reactive resin, but is still capable of absorbing oil at a very slow rate.  This microscopic difference creates more continuation and better pin carry without sacrificing traction. 

While typical urethane balls are primarily used by bowlers with a high rev rate, the Covert Tank is a more versatile piece that will benefit more styles of play because it merges this new microcell polymer cover with a strong Torx™ weight block.  The higher differential produces more track flare, which both improves backend motion and also limits oil redistribution.  Traditional urethane balls tend to have lower track flare, struggle with pin carry, and push more oil down lane.

Even the color scheme of the Covert Tank was created with the competitive bowler in mind.  The solid black cover with dark gray pearl NeoMark graphics provides a crisp contrast to the lane surface so ball motion is easy to see.

    Hasn't found a steady home in my bag, but still great

    I've never had to use Urethane. I decided to try this as my first Urethane...and it is great. This ball has gotten me out of trouble for sport shots or when the transition is evading me. It is a nice follow up to my Villain when the line disappeared. I keep it around, but not sure that it fits me personally. I think it is way more strength than the ball chart shows, but that is just me.

    Covert Tank

    Fantastic addition to my arsenal. I can play this on a fresh house shot down and in and start moving left as the lanes dry out. Very versatile and won't overreact. Urethane ball movement with resin ball finish. The pins explode when it hits the pocket!

    Covert Tank Rolls Over and Crushes Pins!

    Incredible ball. When the lanes dry up, and everything is overhooking, this ball has that old school urethane feel, without having to have a ton of rev on it. I pull it out usually game 3 of our competitive league, and it never fails to disappoint. It pounds right through the pins.

    WHAT DID I JUST THROW!!!!!!!!!!!

    Where has this ball been my whole LIFE!!!! I don't think you can move left far enough. This ball will turn the corner and drop a grenade after plowing through the one-two pocket. Unlike my urethane which I loved, It seems like the more I move left the more this ball loves it. It doesn't give up it, turns and carries unlike my urethane. I don't know what else to say, I just can't wait to get back on the lanes. This is my first Motiv ball ever, was recommended to me by my pro shop. All I got to say is you sold me!! I'm yours take me away lol can't wait to try out some of your other balls! I am now team Motiv, LETS GOOOO!!!!
