Additional product information:

The Bonus adds a new motion to the Radical Reliable price point. The Bonus uses a newly developed core with a lower differential .030 and a low RG of 2.48. We are for the first time using our Forged cover (this is the cover we used in the Katana line) at a price point other than Top Shelf. The addition of the Forged cover and the lower differential core design creates a ball motion that is easy to control yet offers plenty of down lane motion and continuation. The Bonus ball motion is stronger than the Intel yet more controllable than the other Reliable price point balls in the Radical line up. As with all our Reliable and Top Shelf price points, we use the hard-hitting popular DynamiCore.

    Bonus solid

    Posted by Robert Way on May 2nd 2021

    Bonus solid I’m a left handed bowler. I’m ball speed is around 14 mph. My Rev rate is around 280 rpm. I recently punched up a solid Bonus. The layout is 80 x 3 1/2 x 45. I must say how much more this ball hooks on the backend that the Intel solid. It was the length of a Intel but the backend motion is a least 10 more boards hook than the Intel. If you look at the flare rings on the bonus you can see it saves all it Energy for the backend. I think this is a great addition to the radical line. Looking forward using this ball a lot.

    The Bonus replaces my Intel as my benchmark dream ball. The smooth predictable motion not only makes this ball perfect for the THS but also ideal for those challenging sports patterns. I love that I can keep this ball in front of me when they are tougher and open them up when the pattern dictates it. The Bonus comes with Dynamicore technology giving you that extra striking power for those off hits. I highly recommend everyone has at least one of these in their bag. I have two :)

    get out of jail card

    Advertised as an intel replacement, I was excited for this one and it hasn’t disappointed. I drilled them identical and for me they are really close, I have the bonus just a hair longer and a hair more on the backend. This ball has really excelled for me on a couple different situations. I really like it to start at a couple centers that have a little drier house pattern on the fresh, also its really good for me a little later in the day when I need something to blend out the pattern if im getting a little over/under after they’ve been beat up. Another thing I like is I really feel like I can manipulate this ball and have a lot of versatility with it based on hand positions. No matter where Im going this one always makes the bag.

    Radical Bonus

    Posted by David Meyer on Jan 27th 2021

    The Bonus is the most predictable bowling ball I have ever thrown to date. The Bonus is smooth, continuous and is the benchmark ball in my bag. Versatile is another adjective that goes hand in hand with the Bonus. Radical has outdone themselves with this one. The Bonus is a must have in the bag so visit your local Pro Shop and get yours!!! “WOW!!! That’s Radical”

    The Bonu$ from Radical should be one of the first balls out of your bag. It has that smooth, but not too aggressive reaction. It's surprisingly very clean through the fronts and delivers a strong backend finish. You will not be disappointed when purchasing the Bonu$

    Radical Bonus

    Posted by Manny Castillo on Dec 11th 2020

    The Radical Bonus is my benchmark ball. It’s my first ball out of the bag because of its lower RG and low differential while pairing it with its solid combo. I’m able to use it on several patterns. The ball is extremely smooth but DOES not lose any hitting power. The cover is very versatile and takes surface adjustments well. Put your favorite layout on this ball and you’ll see this ball becoming your benchmark ball like it has for me.
