Storm Pro Motion Bowling Ball

(39 reviews) Write a Review
To create this very special PRO-Motion, Jason teamed up Storm’s Research and Development department to create a weight block design that is unique and benefits bowlers of all styles. It is a dynamic symmetrical piece that has some very unique characteristics. For bowlers looking to roll their best scores, the PRO-Motion gives total performance from foul line to head pin with a ball motion akin to the pros'. THE ENGINE OF CHANGE The Piston core brings with it months of testing and validation in conjunction with the best player of our time: Jason Belmonte. Developed specifically for his line, the Piston Core creates separate helical archs that make the shape corkscrew as it tumbles. You can see the channels on the sides of the Piston Core and the large band through the equator which displaces the mass in a very specific way.

    If you want consistency and smooth with urethane like ball motion but reactive hit, then here you go. The Piston Core with the SPEC cover really complement each other. I keep mine at 2000 grit and it's the first ball out of my bag on league night. Because it covers all the medium lane conditions it is a great benchmark ball. This ball will not over-under on a typical wet/dry house pattern and will keep you in play and out of trouble on tougher challenge/sport shots. Stronger than an IQ tour but less than a Phaze II. You don't need 2 hands to throw this ball! The Strokers and Tweeners can play their "A" game and play the oil line effortlessly. Smooth and steady wins the race here. Do your favorite pin up layout with this one. It carries the swisher hits as well as the high flush shots. At the end of the game, when everyone else is grinding out 200 even, you will look up and have a 220. The Pro Motion killed it at South Point in the arena. #Stormnation

    Hello Everyone how goes, just wanting to take a little time to talk to you about the Storm Pro Motion. First off I really don't mind the once colour choice for this bowling ball really nice blue colour with nice logos. 2nd thing is im really a huge fan in the iq tour,who isn't a fan of this ball lol.3rd thing is that this ball is so smooth and controlling sometimes to smooth,reminds me of a iq tour but stronger.Ive used this ball on lots of patterns and works really well on all of them,lots of midlane able to control the backend very easy with this much midlane reaction.One thing for sure is this ball really tends to shine up very fast,thats cause of the slower cover spec,great ball for multiple parts of the lane ball I would for sure have in my bag everwhere I go.I know alot of bowlers might of not of like the first 2 belmo balls that were out but for sure this is something I belive bowlers should try and have in there bag.

    Pro Motion - RG 2.52 - DIFF 0.049 - If you are looking or a benchmark ball this is for you. This ball features the SPEC cover that has quickly became one of my favorites. The Pro Motion with the new Piston core gives you a different motion than the previous two collaborations with Jason Belmonte. This ball is going to get lots of lane time on all kinds of conditions. This ball has allowed me to have success on house pattens as the ball doesn't over react to fiction but the cover is strong enough to hook in the oil in the middle of the lane. Also this ball has been huge on sport patterns as it is my go to with the smooth motion and the predictably it offers. I put this one next to my Phaze II in my must haves.

    The Promotion is the 3rd ball in the Jason Belmonte signature line. For me the Timeless was decent and had its place for certain lane conditions. But it was a little squirty at times. The Storm Drive was really early and smooth down lane. Which also for me it ended up being a conditional ball. Now with the Promotion it is a different story. With the new Piston Core and wrapped with the Spec coverstock the Pro-motion can be used for multiple conditions. I drilled mine with a 5 inch pin up with cg stacked. I added step 2 compound to the surface. While the Pro-motion needs some oil up front, but the down lane motion is very controllable. It's hard to explain but the motion is just different than anything we have in the line today very unique motion. I think it fits just below the Phase 2 in overall ball motion but stronger than the IQ series. Or maybe a stronger beefed up version of the IQ tour.

    So, where do I start? The ProMotion is really good...thanks for reading. Ok, maybe it's not that simple but, it is a great ball. This is the third signature ball from Storm and Jason Belomnte following the Drive and Timeless. They stayed with a symmetric design once again with the Piston core shape, this block produces an RG of 2.52 and a diff of .049. Pairing Storm's SPEC cover and the Piston core creates, by far, the most continuous motion that I can remember seeing on the lane. We released a ball review on our channel, Callahan's Performance Bowling, with three testers, one traditional and two two handers and it is impressive watching ProMotion go down the lane and through the pins. It reminds me of a Phaze II as far as the shape with more roll on the back end. I think this release could find a home in anyone's bag, I wouldn't call it a bench mark due to the strength but, it has the predictable look that you want on a fresh block or league condition. Team Utah and Belmo at it again! Great ball, go get one. Thanks for reading

    The ProMotion features the SPEC (Storm Performance Enhanced Cover) and the new Piston Core. The ProMotion in my opinion is an IQ Tour Solid on steroids. The IQ tour solid is one of my all time favorite balls and the ProMotion gives me a similar ball motion when bowling on heavier volume and longer oil patterns. The ProMotion is a very versatile ball and allows you to play multiple angles on the lanes.

    This is by far the most versatile ball I have ever had the pleasure of throwing. It is so buttery smooth and predictable that I can use it on almost any shot thrown my way. On top of that the continuation is so strong I almost never leave ten pins with it. Yes, SPEC loves oil as does this ball in particular but I also have thrown this ball on a house shot many times with amazing results because of how controllable and predictable it is. I do not have to make big moves with my feet as this ball blends the pattern so well, it's almost as if it gives me subtle warning signs that transition is happening without completely washing out or going through the nose. I will be buying another one if not two of these balls at least for tournaments. Do not hesitate to buy this ball, it lives up to the hype and then some!

    One of the most versatile balls I have ever drilled. Love the motion this ball gives me down lane. Very predictable smooth and continuous. This ball hooks a ton but its gradual down lane and doesn't lose anything going through the pins. Originally didn't think that this ball would fit my game so I was hesitate to drill it ..but since I have I cant get it out of my hands . The pro motion seems to blend out every condition I use it on .. loving the promotion

    The Pro Motion is very versatile, I am able to play any part of the lane that I need to and not sacrifice carry. The ball retains its energy very well which allows it to go through the pins well. I have tried the ball at a number of surfaces, I have found that having the ball at 3000 helps it read the lane well in the mid-lane while still allowing me to use the ball anywhere on the lane. I did not have a lot of success with the previous Belmo releases, however this ball is in a league of its own. It is far and wide better then the other two Belmo releases. I strongly recommend drilling this ball if you would like a versatile ball that is able to play up the boards or get in and loop the lane. https://www.youtube.com/watch?v=hg-aw61gVvw

    I really wanted to wait a while to release this video to give myself adequate time with the promotion. Since drilling, I've put about 100 games on it and still continue to throw it all the time. SPEC is truly an amazing cover. With its ultra slow absorption rate, I find myself able to stay in the same piece for a longer duration of time. This combined with the lower RG and higher Diff core provide a very smooth and predictable motion without sacrificing continuation. Throwing it all three games of league or the middle chunk of a tournament block is never a problem. What really sets this ball apart from anything else on the currently market is it's continuation through the pins. I honestly surprise myself with how continuous the ball is from every part of the lane. It somehow manages to strike a ton with steeper angles as well while still remaining very controllable. As you can see, we both decided to compare it to the Phaze ll. The phaze ll provides a slightly cleaner and faster look compared to the promotion.

    This ball will store up all its energy and release it all at once on the pins. It gets through the heads easily and reads the mids great. Once it finds the friction it's like watch pac man eating ghosts. It destroys the pins. You can literally watch it load up and release the energy. This is a great benchmark ball.

    I drilled my Pro Motion up 4 3/4" x 30*. I have been putting 2000 or 3000 depending on what pattern I am using this on. I get a type of strong benchmark motion out of this ball. I have been able to use it on league using the strong cover to blend out the puddle in the middle. I also get good traction on longer patterns and use this as a ball down option when my Halo is too much. The cover is very needy as i do have to clean or scuff it after any real usage.

    Storm PRO-Motion Cover: SPEC solid Core: Piston Layout: 3 X 4 7/8 X 1/2 With the Storm PRO-Motion, we have the 3rd collaboration between Jason Belmonte and Storm. I drilled two Crux Primes which share the SPEC solid cover with the PRO-Motion. I love how slow the SPEC cover is and how it seems to almost simplify moves. But, as we all know, a slow cover with a big asymmetric core sometimes has a short use window. So, bring on Belmo and the PRO-Motion. We now have a symmetric option that is naturally more continuous and a bit more poppy off the spot. I still find the PRO-Motion slow, but it has a longer use window and matches up very well on medium length/volume house patterns and a variety of sport patterns. I drilled my PRO-Motion with a little shorter pin to complement my IQ Tour with the same layout and it does just that on the lanes. I think my IQ Tour is overall a bit stronger thru the lane in hook, but the PRO-Motion feels more archy and smooth. I will definitely drill another very soon with a more conventional layout. If you were not a fan of the Timeless and/or Drive, don't be afraid to give this one a try - it is a completely different ball!

    Ball Specs: Storm Pro Motion 2000 SPEC™ Solid Reactive Weight Piston™ Core (Symmetrical) Color Steel Blue Review: WOW! We feel this is by far the best of the Belmo signature line balls. This ball is comparable in wow factor to the legendary and original Hy-Road. You can compare the ball reaction to that of the Phaze II. Storm did an incredible job on R&D for this product. This ball is incredibly smooth and predictable. The cover and core work very well together to showcase what many call a "benchmark" bowling ball. Versatile on many different parts of the lane on very different conditions, this ball can virtually be thrown by any type of bowler. Those of you who may think you need to use 2 hands to throw the Belmo signature line, please think again... you may be missing out on something SPECtacular!

    This new Pro Motion is a beast for heavier oil conditions! If your looking for your next heavy oil go to ball this is it! The new Spec Cover wrapped around the all new piston core is strong but controllable at the same time. Storm and Belmo have really created a real head turner with this one. I drilled mine 60x3.5x40 to try and use this ball for heavier oil conditions as well as still being an option for league when the lanes are a bit tighter. So far this ball gives me a ton of forgiveness in the oil and is not a stranger to the dry boards either. I get complete control when I need it most, right out the gate when the lanes are still opening, even with my lower rev rate this baby still makes me look like I'm hooking It with the big crankers.

    My drilling I used is a simple pin down layout about 4 inches away from my pap. Storm's new collaboration with Jason Belmont's has given the world a very unique bowling ball called the Pro Motion. With this SPEC Coverstock wrapped around the all new Piston Core this ball will provide you with a Storm benchmark shape in a bowling ball. I personally have been able to throw this on the shorter oil patterns including Cheetah as well as throwing it on the longer oil patterns for just a controllable ball motion. Jason Belmonte and Storm you've hit a grand slam with this one.

    Excited for this ball would be an understatement. This bowling ball is in Storm's Signature line developed by Storm's Research and Development Department Hank Boomershine and Storm's Professional Bowler... the #1 Bowler in the World Jason Belmonte. Combining the thoughts of Storms R&D team and Jason Belmonte produces a ball with a unique shape, one that is smooth and controls the break point. At 15lbs the bowling ball has an RG: 2.52 and DIFF: .049 which creates a motion bowler's need in their bag! I drilled (2) different Pro Motions. One with a 5-inch Pin to PAP and 50-degree Val Angle and the other with a 4-inch pin to PAP and a 35-degree Val angle. I was able to create a smoother rounded shape with ball 1 and a stronger down lane motion with ball 2. The Pro Motion uses the solid SPEC coverstock also found on the CRUX Prime. A strong and versatile coverstock combined with the new Piston Cores creates a ball shape I was missing in my bag. Sanding the ball to different surfaces from 1000 to 4000 and even adding polish to the bowling ball allowed me to play different parts of the lane and create the ball shape I was looking for at different bowling centers and at local tournaments.

    I am angry at myself for sitting on this one for so long! The Pro Motion is the 3rd ball in the Signature Line featuring Jason Belmonte's Logo and suggestions in the R&D process. Knowing what balls Belmo has been throwing a lot of on tour over the last year, it was no surprise that it was very Phaze2-ish. I knew that this was supposed to be the newest "benchmark" ball and that Belmo even said that it's the "best ball I have ever thrown." Well that's A LOT of hype. After the Crux Prime, I wasn't totally sold on the SPEC cover. I really did my homework with this ball, asking lots of questions and watching every video out. It took a conversation with a pro staffer for the curiosity to finally get the best of me...The verdict is, I can't believe it took me this long to drill such an amazing ball. The Hype is real. On the fresh, this ball is clean through the fronts, provides ample mid lane read, and has AMAZING continuation through the pins. I will be shooting a comparison video soon, look for it on my youtube channel! https://www.youtube.com/channel/UCQGnqqbw86syZ0hwIDtQ8sA?view_as=subscriber

    Pro Motion for me gives me a predicable smooth reaction down lane. I was able to move left out of my comfort zone and still have confidence that it will still recover and go through the pins. This ball will give you that benchmark reaction on higher volume and long patterns. Compared it to my phaze 2 and I seen that the phaze 2 got down the lane a lot cleaner. I had to move about 4 and 2 right compared to the Pro Motion. Video link Below. https://youtu.be/4emNYeQsILg

    The third installment into Storm's Signature series is the PRO-Motion. The PRO-Motion features the Piston Core and SPEC Solid Reactive Shell. This combination of core and shell allows the PRO-Motion to rev quickly in the oil and still maintain enough energy for the backend. I was surprised by how much the PRO-Motion actually hooks on the backend. I compared the PRO-Motion to the Drive and the Timeless and the PRO-Motion was far more forgiving and more versatile then those two other nuggets. The layout I used was 5X5X2.5 or simply pin above my ring finger and cg not too kicked out. Off the drill press on to lane the PRO-Motion reminds me a lot of a Phase2 upfront with the backend motion of a HyRoad. On a fresh House Pattern I had unlimited room as long as I kept my angles close to the oil line. The PRO-Motion does need a little help to get down the lane but it is consistent off the dry. I was waiting for the PRO-Motion to lose energy as I moved left... It really did not happen as long as I did not throw it directly into the dry too quickly. My rev rate is on the lower side (around 300) and ball speed is medium (15mph to 16mph) so usually moving left and following oil line will result with over under. The PRO-Motion blended out the pattern nicely and I just had to keep the ball on line. The PRO-Motion went through the pins the same way whether I was playing 5 or playing 15. The Signature line was UPGRADED with the addition of the PRO-Motion. Power and Performance that smells like Vanilla Snap!

    Ladies and Gentlemen, may I be one of the first to introduce you to a ball that has redefined the definition of a bench mark bowling ball. Jason Belmonte and Storm bring you the Pro Motion. The Pro Motion has the Spec Coverstock featured first on the Crux Prime and an all new core design called the Piston Core. In 15lbs, the RG is 2.52 and the differential is 0.49. The motion I see out of this ball is a very controllable motion, but a controllable motion like I've never seen before. The ball gets through the fronts with ease, see's the middle part of the lane and keeps continuing through the back end and the pins. There gets to a point where your bench mark ball has reached it's limit as you migrate more towards the center part of the lane, but with this pro motion, it doesn't stop continuing no matter how far left (being a right hander) you get with it. This ball is quickly becoming one of my favorites. I like to stay in benchmark bowling balls as long as possible because I really like that shape, and with this pro motion, it's allowed me to play from very far right, to lofting the ball return and still maintaining great carry. You won't want to miss out on this bowling ball! It has revolutionized what a benchmark ball needs to be!

    Storm's new collaboration with Jason Belmonte is an absolute MUST for tournament bowlers. I have thrown this ball on multiple patterns with different volumes and this ball just NEVER quits and always continues through the pins. It is as smooth as an iQ Tour but as clean through the front part of the lane as a Phaze II.

    Ball Specs: Storm Pro Motion Spec Solid Reactive 2000 Grit Ball Specs: Symmetric Core Layout 65 x 4 x 30 Bowler Specs: Right Hand. PAP 5" Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The New Storm Pro Motion is the third ball in the "Belmo" series of balls. I did not care for the Timeless, but I really like my Drive even though it was not a popular ball. The Blue sanded reactive finish looks good to me even though I have had a few ask if it was a traditional urethane ball. I like the mint smell also. The Pro Motion has the same Spec cover as the Crux Prime wrapped around a brand new core. Storm set out to make this ball react well for many different bowler styles. I know the Belmo fans where excited for this release and I heard varying accounts, so I was eager to drill one up. My first impression was though the Pro motion had the Spec cover it was not a hook monster like the Prime. I first used it on a medium house pattern and it was too early and strong. My next test was done on an oily, modified house pattern and it didn't see the lane soon enough. I then put it on a long flat shot and there was where it really worked well for me. I was able to play outside and let the Pro Motion roll up and hit. I was never worried about over and under reaction. In all the patterns the ball was very predictable and continuous. I think this ball will best suit the no thumb bowlers and high rev players. The ones I have drilled have been well received by the no thumb crowd or bowlers who want a smooth motion. The Pro Motion will fit between my Crux Prime and Drive. Summary: The Pro Motion has a very smooth roll. The Pro Motion is very predictable. When you match up with this ball it lives in the pocket. A good choice for the rev dominate bowler. Glenn Wendel PBA Member Storm Pro Shop Staff gwendel@comcast.net www.stormbowling.com

This might be Storm's best ball ever. It makes a really unique shape. You'll have to throw it to see what I'm talking about. For me it was a nice benchmark ball. Strong enough to use right out of the gate, but it never misses the breakpoint. AND the backend motion and continuation is unreal. It's truly a "PRO MOTION"! I was not a fan of the Timeless or Drive, but this is NOTHING like either one of those. The Pro Motion is a special ball.
