I have been able to use this ball on different conditions and now feel I can offer a good review. Please see this video for layout:

The cruel easily clears the heads. I was afraid that what is supposed to be a strong hooking ball might have issue with doing this. With the layout I have, the cruel gives a very positive read to the mid-lane, while actually staying very controllable on the back. I have used this ball on heavily oiled middles and found it had no issue with making the turn at the back when keeping the ball in the oil. Other balls in my bag, (QZ1 red & SR2) pushed a little too long when playing this same area.  The cover has slight shine to it OOB and is best suited for med-heavy conditions. After throwing this for a while with the OOB surface, I decided to hit it lightly with a gray scotch brite as the ball had glazed slightly, as to be expected. This in when the ball really started to kick. While it still easily cleared the front, the back end reaction was  more positive and pronounced. The reaction shape was hockey stick like but with good continuation. All in all I find this ball to be very versatile, in that you can use it for a while when you pull it out of the bag. It is not like some other heavy oil balls I have thrown, that as soon as the puddle starts to dry up, the ball burns early and loses energy and becomes useless. I like this ball so much I am considering another really polished, as I think it along with the one I have, will give me two balls that compliment each other very well.

layout #1 (pin up)
5 5/8 pin, 40deg x 25deg, highly polished

layout #2 (pin down)
4 1/4 pin, 50deg x 60deg, 1000 ab. pad

layout #3 (pin up)
3 7/8 pin, 50deg x 35deg, box surface

This ball is a monster of a ball.  I've used this on a variety of shots and it has proven effective on most of them (except the short dry pattern, it's simply too much ball)
On your THS all three are very effective and crush the pocket.  Depending on which one I'm using will determine how far left I stand, usually 30-40 depending on which ball.  
These balls destroyed the Shark and Chameleon patterns I practiced on!  This ball gets down the lane very well and doesn't over react to the middle part of the lane and has a very strong continuous finish on the back.  #2 is the strongest overall for me, #1 is the most skid/snap and #3 is the smoothest, but still stronger than #1.  
For those looking for an aggressive ball, this is the one for you!  The surface allows this ball to get through the lane without burning up.  But those looking to adjust the surface, it takes adjustments very well.  It is definitely something different than the rest of the MOTIV lineup, it's backend pop is what stood out to me the most.  Do yourself a favor and put this gem in your bag and be Cruel to the pins and your competition!  

video will come soon, computer and camera problems have kept me from uploading the video.

The Cruel is the latest release from Motiv . . and quite possibly their all around best!  It is also their first venture into the asymmetrical core arena. The core is a low RG, max. high diff. design that means ez rev-ing action & high hook potential.  They wrapped it in the new Formula-5 solid/hybrid coverstock that gets through the heads but has awesome mid-lane read and strong backends.  

I have two (2) Cruel.  First one is drilled w/pin just below my bridge, 50 degree MB-to-PAP w/4.25" pin.  This ball is great in the oil.  Does not squirt in the juice while making a heckuva turn in the backend.  I am a 50+ player and really appreciate the extra help this ball gives me on the heavier patterns.  Really reacted well on the Scorpion and Shark patterns as well as a 40' flat US Open pattern we put out at my center.  Second one is drilled pin just above the bridge w/MB 1.5" right of my thumb hole w/x-hole 5.5" straight across on my mid-line.  This ball give me extra length w/solid smooth reaction off the pattern.  Use this one on medium lane conditions.  Good layout for THS especially if shined just alittle w/Power Gel Polish.  Also, looks really great on the Chameleon pattern.  Both balls are excellent and a very welcomed addition to my arsenal.  If you have ever considered trying a Motiv ball, I highly recommend you try the Cruel C51.  You will be glad you did!

Facing The "Cruel Facts"

                             MOTIV:C51 Cruel Review

My information:Right Handed,Ball Speed-16 mph average,
Rev Rate-280 rpm's average,Axis rotation-45 Degrees,
Axis Tilt-15 Degrees,PAP-5 1/4" x1 1/4 "up.

Specs of balls tested-Ball #1 -Top weight-2.7 oz.Pin 2.8".
Ball Surface-2000 Grit OOB.Drilling-65x60 @4",X hole-P3.

Ball #2-Top weight-3.0 oz.Pin-5",Ball Surface-2000Grit OOB,
Drilling-70x60 @4 7/8",No X hole.

Lanes Tested on-Pro Anvilane- 2 years old.
Pro Anvilane-5 years old,Anvilnes-16 years old.
Wood lanes-30 years old.

Patterns tested on-Red,White,Blue,House shot-42 feet.

The C51-Cruel is the newest entry in the MOTIV
line-up,and the first asymmetric ball from MOTIV.
The all new C51 :Cruel core offers a 2.,48 rg,and a .060
differential with a .030 mass bias differential.

Covering the core is a all new coverstock the Formula 5
reactive hybrid,the first ever hybrid cover from MOTIV.

The color is black/smoke with blood red graphics with
white lettering.The colors are visually eye pleasing.

The cover comes OOB at 2000 wet sanded.

 The intent of the C51 is for medium to heavy oil.

                 The benefits of a asymmetrical core
The asymmetrical core will give you a shorter transition.The
Cruel core allows the ball to get into a roll quicker and easier.
The asymmetrical core of the Cruel is great for lane conditions
that has slicker midlanes.
 Medium and lower rev players will love this ball when the
area past the midlane point is not reacting enough.

 Higher rev players can use the Cruel for control on the back end
where there is a little more friction in the midlanes.
The C51 goes into a roll quicker,and will not break as hard
and sharp through the pin area.This offers control when needed
for higher rev players.

 What I got from the Cruel was a ball that revs up                         early and hard in the midlanes ,but cleared the heads
easily because of the hybrid cover.I got about 5" of flare
from both drillings.The Cruel was at it's best from the mids
to the pins.It had a very quick response when it come in contact
with dry at the backend of the patterns.The length was very
nice from such a powerful core.The reaction and the ball shape
at the backend of the pattern was very heavy and angular.

  The recovery down lane was very impressive,the amount
of area the Cruel creates will allow you to miss right,and
still have enough energy left to make it back to the pocket.

  The Cruel let me play a more angular line to the pocket.I
could more further left and still have enough energy left
to make it back to the pocket.For me this is a very welcome sight.

 The Cruel ate up  the R/W/B patterns.On the house shot,
just hit the pocket and carry was far and above anything
I have seen in a long time.

 For those of you that have tried MOTIV ,you will really
be impressed with the Cruel.For those that have been
waiting for a ball of this type.Well now is the time to try MOTIV.

The Motiv Cruel C51 is the newest and deadliest weapon is the Motiv arsenal. It combines the All New asymmetric core design with the new Formula-5 Reactive Hybrid coverstock so it inflicts some serious damage. Beware its now a Cruel world we are living in.

The Cruel is designed for medium to heavy oil. But what I like about the Formula-5 coverstock is that you can alter it very easily and it makes this ball very versatile for any types of lanes. I gotta put my hands together cause Motiv keeps impressing me. Here is a link to my Cruel C51 ball reaction video. Enjoy! Stay Motivated!

I have drilled up my Motiv Cruel C51 with a dual angle layout 65x4.5x55. I also put a light polish on the factory finish. The first time I used the ball was in a tourny on the 2010 PBA World Championship pattern. The ball was so smooth and hard hitting on the fresh. It wasn't over aggressive and had alot of recovery room if I missed right and still held if I tugged it a board left. The carry on the ball has been tremendous. A light hit sends the pins flying and I have carried stuff that other balls would have left the back row or 7/10 splits. When the lanes tried out all I had to do was keep moving left and eventually like in game 7 and 8 I was swinging the ball really well and even on the dried out pattern the ball never over reacted and started hitting even harder.
I also tried this same ball, taking it back to box finish, on the Shark pattern and was able to play the outside of the lane were people say your not suppose to beable to play and had a great look. Same reaction on the ball as previous pattern. Once that line went away I could move into the track area and got a good read from in there also.

Bowler Stats-Ball Speed 17 MPH Rev Rate-App 280 Axis of Rotation-30 to 60 degrees Axis Tilt 9 degrees Right Handed

The Cruel C51 ball is designed for medium, heavy or long  oil patterns. The ball performs as advertised. It pushes through the heads with ease as on fresh shots.   As the ball gets to the midlane the core starts to take over and you can visually see the ball rev (thanks to the Neomark graphics) up.  As the ball finds the friction a strong but not flippy reactions occurs.  For me the pins stay low and I have thrown more scouts/messengers then I have with any other ball (I don't throw many pins around the deck).   I am able to use the C51 playing both down the boards as well as swinging it out to the dry. The ball recovers well, but when the volume in the heads starts to wear out, the ball picks up earlier.   As long as the Cruel has sufficient head oil it is a very effective ball.

I've seen the ball perform well on a 42 foot US Open Pattern where it actually gave me room to the right (relative to the other players) and I've thrown in on fresh THS on both Wood and AMF Synthetics.  The Cruel does not seem to have a surface preference as it reacted well on all surfaces.

If you use this ball as designed on fresh or long oil patters,  it is a very effective ball. To throw it on a broken down THS or a Sport Condition with a few games will take more ball speed then I have.  

The C51 gives Motiv a piece of equipment for Motiv believers to step down to when their TR2's are too much or are not creating the correct angle to carry.  While I've found the TR2 to be most effective up the boards, the cruel can be played up the boards, or swinging it out.  I'm very colorblind but I've heard from multiple bowlers that the ball is very pleasing to the eye and will give it good shelf appeal.

this ball is a must have. i just joined motivnation with their recon rx-1 with is also a must have.
stats: 15mph
revs: 265
tilt: 14
axis: 70

i bough this bal for longer oil patterns. since i dont have a lot of speed or revs i went for a ball maxed out like htis one, and put wahts considered an average layout. no to strong.
i laid it out 55x4x30 with a p4 hole which ended up being 1 1/2 right of my thunmb which is considered a double thumb. a 1" hole 3" deep pitched 3/4 right.

this ball stores its energy and makes a late mid lane shift, then turns direction and drives right threw the pins. great energy, great pin action, barely deflect.
this is their first assym, ball and hybrid cover and this ball is better than my c system 3.5 by far, and better than my Hammer Jacked which i still love and kicks butt. If you havent thrown motiv now is the time to switch. DO IT!!

check out my video on this ball

Drilled 2 Cruels, one with a 5" PIN to PAP and 4" PAP to MB drilling, and the second with a 4" PIN to PAP and 4" PAP to MB. Both balls left with box finish...
All I can say is that these balls both compliment themselves on a variety of animal patterns, with exception to Cheetah, which I found them to be too strong. They both roll strong and smooth with a continuous arcing motion, which helps makes it easy to make changes when needed.
On the THS, they hit harder than anything I've seen in a long time...Once again, MOTIV has come out with a ball that helps open up the pocket and improve pin carry!

If I could get one lucky hit...

yes had one drilled fairly strong. this ball looks great but is nothing special. leaves a lot of stone 10s lots of solid 8s. and hooks no more than my old eraser drilled about the same tried scuffing it litely with scotch brite and it did hook more. but shined back up quickly. on fresh its very over under for me. I dont see myself buying anymore motiv balls

Me -
Power Tweener - 17+ mph
Rev rate 340-380
Average 220+ (house), 200 (sport)

The basics
Out of box finish (2000 AB)
Pin 5" and above fingers.
Cg lower right
MB lower right below thumb

This ball is just plain awesome!
I was looking for something to combat the heavy "league puddle" or longer sport patterns. What did I get? All of the above and more.

The Cruel has a core/cover combination that revs quickly and has a very strong midlane, but can still get thru the heads and have hitting power with little deflection. I expected it to hook earlier, making it a first game and put it away ball. but, the Cruel is so versatile that it reads the lane great and doesn't hook at your feet and quit.

I honestly feel that if you had 3 of these drilled differently. you probably wouldn't need anything else in your bag except maybe a spare ball. Combine that with amazing looks (thanks to those Neomark graphics), and this thing is nothing but a winner.

Better get you one before the competition does.

Its a "Cruel" World out there!

The MOTIV Cruel C51 features the 1st asymmetric core design.  Its lower RG  allows the ball to rev up easier in the front part of the lanes. The ball has a very strong mid-lane reaction and still stores enough energy for a "nice" pop at the break point.  The Formula-5 Reactive Hybrid is the most aggressive cover stock MOTIV has ever designed. I got the best results out of both of my pin-up & pin-down Cruels on a medium to heavy oil pattern.  I got a 5" flare out of both lay-outs.  The ball is sooooo smooth through the front part of the lane for such a powerful core.  I would highly recommend this ball being added to everyone's bag because of the control, versatility and performance it is going to give you on various lane conditions.

The Cruel C51 features the hybrid Formula-5™ Reactive coverstock. It is the strongest yet by Motiv and matches up on medium to heavy oil.

Box Finish
The factory finish on the Cruel C51 is 2000 wet sand.  This finish will provide an aggressive reaction with length and a very strong backend with continuation.

Inner Core
The Cruel core is the first asymmetric design from Motiv and it is very aggressive. The specs are maxed out. The Cruel C51 has an RG of 2.48 and a .060 diff and a .30 mass bias differential (15# ball).

The MOTIV™ Cruel C51 features an awesome NeoMark graphic.  And, as with all NeoMark graphics, the logo is actually part of the coverstock so it can be sanded, polished, or tuned just like any other performance ball.

First Cruel C51 drilled:
Axis Point - 5" over 0" up/down
Pin to PAP- 5" (pin located below fingers on midline)
Mass Bias Placement - strong
Balance Hole – small hole 2 ½’’ below axis point
Dual Angle Layout - 45* x 5" x 70*
Surface Preparation - Out of Box (2000 Wet Sand)

Second Cruel C51 drilled:
Axis Point - 5" over 0" up/down
Pin to PAP- 5 1/4" (pin located above fingers on midline)
Mass Bias Placement - medium
Balance Hole – small hole just past axis point
Dual Angle Layout - 45* x 5 1/4" x 45*
Surface Preparation - Out of Box (2000 Wet Sand)

If you bowl on medium to heavy oil patterns this bowling ball is a must. Pin up ball works best on medium conditions where the pin down ball dominates on heavy oil. I have also been able to play with the pin up ball on house conditions but when the pattern transitions the Motiv SR2 comes out of the bag. This ball was a must in the Motiv line since now it can compete with those other companies in the high-end aggressive coverstock market. Now all that is needed from Motiv is an aggressive asymmetrical pearl and oh yes a spare ball!

Ball spec's 15lb. 3 oz top, 3.5 pin. Drilled 50 X 4 3/4 X 65. WT hole at P0. This puts the pin below my ring finger. This has been one of my favorite drilling.

Got a chance to use the Cruel on our challenge league. To start the season we are bowling on a 39' foot medium volume oil pattern that starts out a little under 4-1. Not your normal house shot (7 or 8 to 1) but not impossible to start.

The Cruel comes 2000 Wet Sand, it handles Med-Med heavy oil with this surface. This ball needs to have some oil up front even with the box finish. During one practice session on some very used open bowling lanes I could not get the ball down the lane in box finish. The cover stock is versatile, change the surface to 1000 and it will the heavy stuff with ease. I have not tried any polish on it yet.

The first thing I notice (even in practice) about this ball is the carry. If you can get it to the pocket its a strike. I have never had a ball that the carry is this good.

This ball makes a strong controlled move at the break point with the 65 degree val angle. I can see using this ball on over 50% of the normal conditions you see. I have other equipment for the extremes of heavy or light oil.

With the Cruel I was looking for something to fit in between my sanded TR2 and my TX1 at 2000k with lane shine. The Cruel fits that gap perfectly.
