Another wheel fell off...

[PMK]

I'm no expert but I work in the engineering field. With the quality of simulation software engineers are able to test all sorts of parts/designs/ideas for various types of failures before the actual part is ever built. The software is expensive and BRP is running the Dassault Systems suite of tools. These are the same tools many aerospace companies use (boeing, Airbus, etc) to simulate designs. The software is very accurate. I'm not saying it never happens but typically, in today's world, if a failure takes place its a materials/manufacturing issue rather than a design issue. You can't completely release the engineer/designer from the hook because its possible they design something difficult to make and that leads to a materials/manufacturing issue but in general an experienced engineer would know if a design will fail long before its ever built.

CATIA is an excellent program. As mentioned when correctly used, it does offer an immense capability. I do agree also that it does very well at predicting time to failure or first failure location.

Without doubt, if the issue is identified as defective raw material, there is no means to predict anything more than replace the part.

Regarding what software or evaluation is utilized by BRP, the end result is the fastener failed. Defective material could happen in solid material or hollow material, so that is an interesting remark.

No doubt BRP will sort it out and restore confidence.

There's a novel thought.

I found info. on reason for cracked nuts. HOLLOW extrusions caused COLD SHOTS. The 3rd picture are example images of Cold Shots....NOT Pictures of nut defects!

I have total confidence in BRP. I haven't been easy on mine and have had no problems. If there was a design issue it would have shown up on mine by now. I believe it was just what they said, a bad batch that they discovered and are now correcting.

I bought mine 900 on feb 7. I have hit I don't even know how many bad bumps. Mine seem fine so I agree it might just be a few of them, not good if your one of them though. I pulled a wheel a few months back and as I recall the nut was quite heavy- maybe solid. At any rate that should have never happened. If I had one that was in the time period of the flawed nuts I would park it until the new ones were replaced.

 

[canamryder]

You most likely have nuts that were manufactured pre 2/19. On the frame, under the seat look on the label near the upper right corner. The build date is there. I bought mine 7/19, but build date is 10/18.:yes:
All the nuts are heavy and solid. "Hollow" extrusions mean the were made from a long piece tubing (like a straw with thick walls) If the bar stock was maybe 10' long and the nut maybe 1 1/4 thick, the bar would be cut up to make close to 96 nuts. I don't mean to play Mr. Teacher, but you noted that you thought the nuts felt solid. That threw me off....they're all solid. Well except for the flawed ones. You wouldn't know the difference in your hand.

Mine was made 5/19, no cracked nuts, no weird problems, it just goes. New nuts on order though per the recall. Bit I do maintain y stuff also. I don't just hop and ride and not check things over.

So are you saying that these cracks are visible prior to the nut giving way, KC61? If the cracks are not visible, I don’t understand how checking things over before you ride would show anything untoward in this case.

I visually inspect them and just today I checked the torque of all 3 wheels as well as the air pressure. That's what I mean by not just hopping on and riding. I guarantee you if the OP would have done a visual check of things before he took off this more than likely wouldn't have happened. These things always get blown out of proportion.

Not blown out of proportion at all. When a Recall is issued it IS a big issue - and wheels falling off is about as bad as it gets.

There are like 7 documented cases and the recall isn't a "Do Not Operate" the vehicle type of recall. No one knows what caused this guys wheel to fall off but it was supposedly just at the dealer. So draw your own conclusions. All I'm saying is this isn't some widespread issue and the internet does in fact blow it out of proportion.

 

[Freddy]

Spyder fires of a few years back were not a widespread issue either nor was it a 'Do Not Operate' recall but it was a BIG issue if yours caught fire - or if a wheel falls off your Ryker these days. It all depends on where you're sitting.

The most important thing that I can see is that every one that have the bikes in the time span of this screw up, be careful!! If you want to ride LOOK them over! Why they would build a wheel nut out of alum just blows my mind! I have spent 40 years in the welding and fab field, working side by side with some really smart engineers, but some times things don't work!!! If all your ducks are in a row, finest kind, but one gets out of that row your #$%^!!! All you need is one bad batch of material and this is what you get! My thoughts are, why take some things to this hairy edge, and put your bacon that far out?? To every one with the Ryker's be safe, ask the questions, and keep your eye on the problem!! P.S, I would have said nuts, but would want to offend any lady's out there riding one!!:2thumbs:

 

[KC61]

I'll make sure I check my nuts often

 

[Wildrice]

I can't think of any other location to save production cost

That would be worse to save money than the wheel lug nut:banghead:

I'm not going to make any friends but I'm getting old and could care less. Reading all the threads and posts complaining about the Ryker BY PEOPLE WHO DON'T EVEN OWN ONE is really getting old!

Amen Brother, couldn't agree more

Nuts!!!

Watch your nuts brother!!! And if I find you beside the road , I will pick you up, even if I don't ride one!!!!!!!:lecturef_smilie: Good Day!!!

And I would greatly appreciate you stopping and helping me. My comments weren't directed at this particular thread. But reading all the posts from the year since the Ryker was added to this forum, the majority of complaining has been by non Ryker owners and it come to a boil at this time. Complaining about the design of the bike, the materials used, the use of the bike, the maintenance and about BRP in general. I love my Ryker and wouldn't take anything for it and have absolutely no issues with it. I have no issues with my Spyder either but they are two totally different bikes with two totally different purposes (at least for me). Yes, they had an issue with a vendor on a batch of wheel nuts, but they are correcting it. I have complete confidence in my Rally and it's design and am just asking that if you don't own one please quit bashing them. There are plenty of sections on here to discuss your Spyder. Have a good day and enjoy the ride.
