Motiv’s new high performance ball is one of the best rolling balls we have thrown from Motiv. The new Impulse V2 core has a shape similar to the original Impulse core used in the Primal Impulse. The core has been manipulated to lower the RG while keeping the five inch flare potential. The Primal Scream covers this weight block with a new coverstock called Whiplash Solid Reactive. This cover provides the most continuous motion we have seen out of a Motiv bowling ball.

The reaction this ball gave us was a pretty remarkable look on the medium test pattern. All three testers were able to play in their comfort zones on this pattern. What was impressive was that during the transition, as the fronts began to go away and the back end to tighten up, we needed to move left to catch more head oil and the Primal Scream showed no signs of slowing down. The ball just wouldn’t quit; it just kept coming and coming.

The cover was not quite strong enough for the heavy test pattern at the box finish. We lowered the box finish to 2000 wet sand on all three test balls to provide the extra hook needed for the heavier volume pattern. The same continuous motion we had on the medium we also had on the wet after the surface adjustment. We kept moving left and never had to worry about the Primal Scream not making it back to the pocket.

The dry test pattern needed the help of some Power Gel Polish. The polish kept the Primal Scream from wanting to read the lane too early like it did at the box finish.

Our sport pattern was at the mercy of the Primal Scream at the box finish. The ball created traction in the oil and was smooth enough off the hook without losing all its energy at the pins. As well as this ball takes to surface changes, even flatter patterns that are wetter or drier would not be a problem with the right finish.

Performance Ratings

The Primal Scream will scream off the breakpoint. This ball not only went left when it exited the pattern, it just kept on going.
This ball is surprisingly clean through the front for a solid resin ball at a sanded finish. Those looking for more length can add polish.
Back End17
The back end is up there with any other ball in Motiv’s history. We do not know if it is just the color, but we could easily see the Primal Scream cover some boards in the last fifteen feet.
Total Hook52
The big back end move pushes the total hook rating up. For bowlers wanting to see even more hook from this ball, lower the finish to 1000 or 2000 wet sand.


Motiv adds a new reaction shape to their line with the Primal Scream. We have not seen a Motiv solid provide this much continuation from breakpoint to pin deck.


There are few things to keep the Primal Scream from being thrown. Super heavy oil or trying to throw it on dead dry lanes are the only conditions which might set the Primal Scream up to fail.

Overall Summary

The Primal Scream is the must have ball for Motiv fans or bowlers looking for a strong, continuous solid ball for use on medium to heavy oil patterns. The continuation this ball has through the entire lane is the big selling point.
