Radical Katana Assault Bowling Ball Features:
The Katana Assault has an RG of 2.501, a differential of 0.051, and an intermediate differential of 0.020. This core yields a quick response to friction and a lot of continuation through the pins. The Katana Assault and the new chemical compound cover known as HK22 Pearl create a new level of backend reaction. This is a Katana on steroids. A monster flip ball, a motion the industry has always craved and now we have brought it to a whole new level.

Once again putting the HK22 Pearl cover on a Radical piece has raised the bar in expectations. I drilled mine pin down as I wanted to add an asymmetrical pearl to my pin down bag. I have only had the control given by the pin down layout in the Max Results. This ball is exactly as expected smooth and strong through the pins. The HK22 cover gives that special punch on the back and carries the slight misses much like the Bigfooot Hybrid. Love this one and I will be getting another for a pin up layout!

The Katana Assault is going to be one of the strongest pearls ever made. They took the katana core and added a giant flip block at the bottom. The cover is a pearl reactive with the HK 22.
I drilled mine 50×4.5×40.
With this layout the ball easily gets through the front of the lane that’s absolute hook monster on the back end it doesn’t die out and gives you that great continuous finish through the pins. This ball is a must have in your bag.

I loved my original Katana. Now with the new HK22 cover, it is back, and better than ever. Being a Hybrid, it fills a gap between my Top Speed and my Black Widow Ghost. This ball fits perfectly in my arsenal.

The Radical Katana Assault is a nice option to have in the bag. It has the new HK22 cover-stock that blew me away in the Brunswick Defender Hybrid. The Katana Assault is a little cleaner getting down lane a bit farther than the Defender but has a stronger, more defined change of direction off the friction. It goes through the pins very strong. If you like having the head pin fly off the wall, this is your ball. They only give me 5 Stars to work with, but I would say it’s a 4.7 star rating.

If you loved the original Katana’s you will love this ball and if you never had one you are missing out!! Really clean coverstock combined with a fairly strong core creating a great smooth motion down the lane and through the pins. What I like most about this ball is I never have a problem with it getting down the lane. It is almost as clean as the Widow Ghost but overall earlier because of the core.

Radical Katana Assault Review
Stats: LH: Speed – 17.0; RPM – 350; AT – 19; AR – 55
Layout: 45 x 5” x 65
Radical’s newest Top Shelf launch, the Katana Assault, is a newly engineered version of the legendary Katana series of balls, featuring several improvements that should surely get lots of attention. The Katana Assault and the new chemical compound cover known as HK22 Pearl create a new level of backend reaction. This is a Katana on steroids. I chose the layout I did to get the ball to roll forward a little sooner due to my slightly higher tilt but transition a bit slower to really utilize that longer, stronger roll phase of ball motion. I have used it on a couple of different patterns and here is my assessment:
42 ft. THS (typical house shot): The Katana Assault has been a very strong, yet predictable ball for the house shot in two centers I frequent. What I love about this ball is that it can handle decent volumes of oil, makes a quicker defined move off the spot, but is still predictable enough to control from shot to shot. Very versatile to cover changes, I took mine from box finish, down to 1000 and back up to 2000 polished, and it responds to all of those very well. If you are seeing too much early hook, take the cover up to 3000-4000, too much length, just sand it to 1000 or even 500, it takes to those changes extremely well! Do not be afraid to adjust the surface to your game, this ball can handle it!
36 ft. Viper pattern: I roll on this pattern every Tuesday, and the Katana Assault was the best ball in my bag on the fresh, alongside the Bigfoot Hybrid. I could play further in the sauce with the Katana Assault compared to the Bigfoot Hybrid, but they played off of each other very well. Projection and speed control are key on Viper, and the Katana Assault at 3000 was the perfect matchup. It rolled forward perfectly and hit heavy through the pins, carrying the off pocket hits extremely well. As the night progressed, I was able to move slightly further inside, roll the ball firm off my hand, and it saw the friction consistently, making my moves easier and more trustworthy, resulting in higher scores and more confidence in the ball.
If you are looking for that quick responding, heavy rolling ball all the way through the pins from a high end asymmetric pearl, look no further than the Radical Katana Assault. Available now from Bowler Builders Pro Shops, and at pro shops everywhere! Join the Radical Revolution today!

I went with a 40x4x30 drilling. My speed is 14.5 and low rev rate. The original Katana has always been one of my all time favorite balls so I was very excited for this one.This ball is very clean, gets down lane longer before making that monster hook into the pins continuing through the deck. I use this ball on medium oil lane conditions and see very little transition only needing to move 3 to 4 boards over a 3 game period.

I’m a left handed bowler. My ball speed is around 14.5 mph. My Rev rate is around 275 rpms. I recently drilled the this ball. I’m layout choice is layout B (45 x 4 x 35). I think is ball is great. I use this ball for my first two games in league ( house shot). This ball is very quick off the spot at the break point. I’m amazed by how well it carry the pins. With Hk22 cover it is very clean through the fronts. And with its dual density core makes it continuous through the pins. Great job Radical Bowling Technologies. Another great piece of equipment.

Stats: PAP 4 over ¾ up, 15 mph, 18 tilt, 275 revs. I drilled mine 60×3.5×20. Designed for massive flip on the backend, this ball will not disappoint. For someone with average to lower revs like me, this ball provides a lot of help on the backend, recovering from parts unknown when I miss. This ball works best for me on medium oil conditions. Do not be afraid to get it out to the friction!
