Additional product information:

U-Motion was one of our biggest ball tests over the last 6-9 months, we understand the need for urethane and tested many different core designs and urethane formulas. The core features a higher RG and lower DIFF for excellent urethane ball motion. The U-Motion will provide consistent and predictable ball motion on any condition and is most effective on lighter volume and shorter patterns.

    Brunswick U Motion

    I purchased this ball to compliment my Purple Hammer. The Purple Hammer I can use on fresh and is a lot more ball, but sometimes you need a different motion to carry. Thats where the U Motion comes in. It is weaker, earlier and far less angular than the Hammer. This ball loves the desert. When the lanes are dry and toasty this is my go to. Normally I start with the Hammer and finish with the U Motion. If you like to throw urethane then these balls make a great one two punch.

    Urethane for the House

    The Brunswick U Motion is a great low volume/short pattern ball to have in your arsenal. Unfortunately, given the pandemic, I have not had an opportunity to use it on medium to heavier volumes, but on the drier conditions I have been able to use it on, it's provided me with some great controllable backend reaction. You can definitely see the predictable ball motion downlane and make adjustments when necessary. I drilled mine 55 x 4.5 x 20

    Great Urethane Option!!!

    This ball is the perfect compliment to the Purple Hammer. I really shouldn't need to say anything else. Where the Purple Hammer has a tendency to go a little too long before seeing the friction, the U-Motion picks up. It's a staple in my bag with the Purple. If you're looking for a urethane ball but this one. You will not be disappointed

    Urethane With Extra Backend

    BALL SPECS Pin Length: 2.5" Starting Top Weight: 3.2 oz Ball Weight: 15 lbs 3 oz DRILL PATTERN Ball: 55 x 5 x 70 X Hole (if there is one): none BOWLER STYLE Rev Rate: 375 rpms Ball Speed:17.5 mph off hand PAP/Track: 4 1/4 over 3/4 up SURFACE PREP Grit: 500/1000 Siaair Type: (Matte, Polish, Sanded): Sanded LANE CONDITIONS Lengths of patterns: 41 foot house shot Volume: Moderate Type: House BALL REACTION Length: Moderate Back End: Smooth Arc Overall Hook: Mild Midlane Read: Smooth and Controlable Breakpoint Shape: Arc COMMENTS Likes: Backend Recovery Dislikes: none The U Motion is the modern urethane reaction I have been waiting for from Brunswick. It gives me some extra down lane motion I have not seen out of previous urethane balls. The U Motion allows me to open my angles and still get the corner pins out. Compared to the True Motion it is a few feet later and has 3 more boards of hook on the backend. This one saw some use already on a shorter tournament pattern playing the gutter and will definitely see more in the future. If your looking for urethane control with just a bit more backend pop check out the U Motion.

    A must have

    This ball is a must have, once the lanes burn up and everything starts to hook more than you like, you can pull this baby out and play your same mark and still control the lanes, such a smooth continuous roll, I absolutely love this ball...if you don’t have one of these in your bag you’re definitely missing out!

    U Motion

    I haven’t used urethane much but after drilling this ball I can see that changing. The U Motion is strong and controllable through the front part of the lane and still retains enough energy to drive through the pins. Great ball to blend out those wet/dry conditions as well as the flat tournament patterns

    Put one in your bag!

    Myself I was slow to get back to a urethane ball but this one did not disappoint. Great thought the front part of the lane and gives a smooth continuous motion to the pocket. If your bowling on older wood lanes or short pattern tournaments this is a great buy for any bowler.

    A new brand of urethane

    The U-Motion is a release from Brunswick that combines the needed characteristics of a urethane ball in today's environment, with the motion to provide hitting power unlike previous urethane pieces. I had thrown a True Motion in the past couple of years, this ball moves for me probably 3-4 boards more (with identical drillings) and the DynamiCore improves the carry percentage. I feel like I have far more mistake area with this ball than I did with the True Motion. For short sport patterns where you need a controllable reaction, or for wet/dry league conditions where you'd like to stay toward the outside of the lane as long as possible, this is your solution. It also adapts well to changes in surface, so if you feel you need to move the breakpoint forward or back, don't hesitate to break out your pads or polish. If you need a urethane ball in your arsenal then the search goes no further, look for a U-Motion and you won't be disappointed. Jeff Poholsky Brunswick Regional Staff

    Plenty of Motion with the U Motion

    The latest phenomenon in the rebirth of modern urethane, the U Motion is a step up from the True Motion. A good 3 boards stronger than its predecessor the U offers an a strong smooth motion with plenty of drive to kick out those corners. This ball will not disappoint and is easily my favorite piece to bet me through those early games on sports patterns.
