Some tracks outlaw them as well. So if they aren't recommend for street use, tracks don't allow them, I guess they are for "display only" bikes :D

Fact - CF wheels have lower failure rates than aluminum and magnesium wheels.

Yes, you can break anything. That's a no brainer, you hit the wrong bump, and boom, your oe wheels are toast.

Some aluminum or magnesium wheels bend, some crack, others go WAYYYYY out of round. Sometimes the spokes shear off at the hubs, etc...

No wheel is invincible, but I honestly put more faith in CF wheels than anything else.

This is not due to safety concerns.

The world of motorcycle racing is fraught with back door dealings and BS "reasons".

Just like the world of automotive racing.

Why do you think Beringer's 4 disc brake set up was banned from half of racing organizations? Because it is technology patented and controlled by one company.

Why do you think the 6 wheel (4 front wheel) F1 car got banned after 1 race? Because it completely dominated the field, and the technology was only available from one company.

Why are seemingly 98% of all wheels in GP racing made by Marchesini or MFR?

Money, and politics. MFR only successfully made it's way into common use on GP tracks because the M in MFR stands for Marchesini.

That is the same Marchesini who sold his stake in Marchesini years ago, waited til his noncompete was up, then renewed his contacts in the upper levels of all the race teams to get back in with a new product.

There are literally hundreds of examples like this, so don't think that if the racers either Use, or don't Use a product, that it actually means anything.

A person needs to make up there own mind, check with there own tracks/organizations. But you cannot blatantly say they are as safe as other wheels, and they are not banned.

I have heard from here, and it is all over the internet, I don't make this stuff up. Several examples on forums, reviews - 19,000,000 hits:

  1. A racebike with carbon-fiber wheels will not pass inspection in most organizations, yet that may be the material most suited to track use.
  2. It is the overheating of the epoxy that causes the delamination issues in carbon fiber rims
  3. They are of course banned in most forms of motorsport and motorcycling.

BTW, I do not own CF wheels (which has no bearing on this conversation anyway), I have not damaged one, I have not been refused from any track/org I have attended. I was merely commenting on an article posted here. So if you want to debate it, please do it with the authors of any of these articles, not me.
 
I have three years, more than 21,000 miles, and probably 18 tire changes on BST carbon fibre wheels. No chipping, no delamination, nothing - except transformational increases in stopping, acceleration and general handling as a result of a 14 lb decrease in rotational mass. I'd buy them all over again.
 
I have a few sets of PVM magnesium wheels and with hard track use and aggressive street use - I have never seen them bend, crack, get out of shape (but, if the wheels did get out of shape - we could have the magnesium wheel repaired if it were a mild bend).

No such "mild bends: to CF. It's carbon fiber flakes for breakfast. Just add milk.

Point is, and it's in your post (thanks for the photos) that you CAN REPAIR a aluminum or magnesium wheel. Carbon fiber cannot be repaired.

When i looked into the Carbon Fiber BST. I heard the same thing what Trauma said that tracks were banning them. It turns out that Moto GP banned them due to limiting "performance cost". I haven't found a track around southern Cal that bans them. Im not sure if any other tracks bans them. Hence the question.

I dont think that should be the point.

The point of the argument/discussion should be if CF wheels are reliable and strong enough for safe use and not aftermath if/when it gets damaged.

BlackStone Tek? BST ? Questions and Answers

From BST FAQ

Q: After an accident, how will I know if my wheel is still safe and usable?
A: One of the good things about carbon fiber is that you can see damage immediately. The first test is whether the tire is holding air. If it is not, the wheel is likely damaged beyond repair. Major damage will show cracks through the rim and the wheel will obviously not be usable. If it holds air, remove the tire and check the wheel carefully. Damage can be superficial in which case minor cracks will be visible in the clear coat, and the wheel is usable. If the cracks are deeper and the layers of carbon fiber appear to be torn, this is more serious and the wheel should not be used. Please feel free to send us photos to help assess the damage for you.

Q: If my wheel is damaged, can it be fixed?
A: Hubs can often be re-used if they have not been damaged. If the carbon fiber is damaged beyond repair, you can cut the spokes close to the hub and send the hubs to us. We will likely be able to fit them to new carbon parts, giving you new wheels at a much reduced price. Your 'new' wheels will carry the 2 year warranty.
If the hubs have been damaged, the wheel cannot be recovered, as the carbon parts cannot have new hubs attached to them.
All repairs should be done at the BST factory.
Wheels can also be refurbished at the factory for a very reasonable fee.
