Performance Analysis
Performance Analysis
The Radical Max Bias wears its design brief in its name. The Maximum Results asymmetric core posts a 2.49 RG, a .050 differential, and a .030 intermediate differential, and that last number is the headline: it is an unusually large mass bias figure that produces a sharply defined, angular breakpoint. Where many asymmetric balls carry intermediate differentials around half that, the Max Bias was engineered for an emphatic change of direction. Radical paired it with the HK22+ Textured Hybrid reactive cover at 1500 grit, a sanded hybrid that digs into heavy oil while keeping a touch more length than a pure solid would allow.
The ratings follow the blueprint: 8 hook potential and 8 pin action against a 6 length rating, the profile of a ball that reads the midlane with authority and then makes a strong, defined move. The heavy oil designation is not a suggestion. With this much core asymmetry and a textured cover, the Max Bias needs volume to operate, and on its intended conditions the big flare keeps the ball in a strong roll through the pocket, which is where that pin action score comes from. Radical’s release footage with staffers like Aaron Phillips shows the ball at home on exactly those conditions.
Two honest caveats come straight from the card: the versatility score of 6 marks a true specialist, and a 1500 grit textured surface needs regular maintenance to keep performing the way the spec sheet says it should. The ball is also discontinued, making it a used-market purchase today.
Who Is This Ball For?
The Max Bias is for bowlers whose problem is too much oil. League players in centers that flood the lanes, tournament competitors facing long or high-volume sport patterns, and high-rev players who want a controlled but powerful hook all match the design. If you have watched your strongest current ball skate through the midlane on fresh, this is the category of equipment that fixes it, and the sharply defined asymmetric breakpoint gives accomplished players a shape they can aim with confidence.
It is the wrong ball for house bowlers on medium conditions, where it will read far too early, and for anyone unwilling to refresh the surface periodically. Treat it as the big-oil specialist slot in a tournament bag, not a benchmark piece. Since production ended after its June 2024 release, finding one means watching the secondary market, but for heavy-oil specialists the spec sheet still reads like a solution.
The Pros
- • Strong hooking power with Radical Maximum Results Asymmetric Core
- • HK22+ Textured Hybrid coverstock provides excellent traction in heavy oil
- • High flare potential creates impressive pin action
The Cons
- • Limited versatility outside of heavy oil conditions
- • 1500 grit surface may require maintenance for consistent performance

Bowlers frequently mention:
If you were ever a fan of the Radical Maximum Results, then you will be very impressed with the new Radical Max Bias. This ball has one of Mo Pinel’s last core designs in it and it was an absolute winner in the Maximum Results. The Max Bias now features the HK-22 additive to it, which allows a bowler to move the breakpoint further down lane but retain its energy and create dynamic ball motion off the spot. I have the Max Bias drilled with the mass bias on my track side, allowing the ball to have a smoother, yet controllable and stronger ball motion through the pins. This ball is super clean and rolls very consistent. This ball is best used when lanes have heavy oil and you want to have predictability when the ball is going down lane. The Max Bias from Radical is a fantastic add to any bowler’s arsenal and this ball will not disappoint!
The Radical Max Bias will be that long oil, heavy volume ball in my bag. I anticipate using early this weekend bowling on the Billy Hardwick Pattern, 44' & 30 mls. I have only used it on a THS so far, but I like the shape it creates. Picks up early but is very continuous for a snow tire type ball. That is probably due to the addition of HK22 into the textured cover-stock formula. It also has a high asymmetry core that will add to the flare potential. If you are a speed dominant player or have low revs, this very well might be the everyday ball you need. I like what I see so far.
Max Bias I’m a left handed bowler a ball speed around 14.5 mph. My Rev rate is around 275 rpms. This ball is a beast. I compared it to my max results. The Max Bias cover is stronger. This ball has more continuous than the Max Results. If you are looking for a ball for heavy oil. Well then this is a great choice. Thanks, Robert way
Max Bias The Max Bias was created to be the ascension of the Maximum Results. It is just that in my opinion. I have the Bias a few boards stonger than the Max Results. It has a strong cover that re Iquires oil to retain energy at the pins. If there is oil the ball has great continuation through the pins. The Max Results was one of my favorites when released and I believe the Max Bias will be a great replacement.
I drilled the Radical Max Bias 90 x 2.25" x 45 to give me a short pin layout, big ball, that would churn in the mid-lane and keep going to deliver predictable motion in the heaviest of oil. The Max Bias is a new version of the Maximum Results, featuring the new HK22+ Textured Hybrid cover, and a stout 0.030 int. diff, the Max Bias gives bowlers the strong ball they're looking for, with the predictability you've come to expect from Radical. I have used this ball on everything from Earl Anthony to Cheetah, and have been able to play inside and outside angles with great results. This ball picks up earlier than The Hitter, but is smoother with the same amount of overall hook. If you are looking for that big ball with pattern versatility, then the Max Bias is for you.
