They are definitely not standard issue wheels, if you have a look at the angle of the spokes, they are aftermarket BST. The superlegerra spokes are straight from the rim to the hub not on an angle.

ffs
the pics a ducati v4 with BST carbon wheels. I think the spokes have rotated with the force before they broke.
The red herring here is Baggers said he knew a bloke who broke a carbon swing arm and then Karl asked the question what has a carbon swing arm to which he got the responses superleggera and the BMW thing.

Here’s a pic of mine next to the Thysenkrupp
I think the Thysenkrupp is a better design. Having said that the newer Rapid Tek BST’s are definitely a different design, I can’t imaging they changed the design and made the weaker than the previous generation, but it’s possible. I also HIGHLY doubt that pic of the exploded wheel was from the guy just pouring on the power down a straight. 10 to 1 bet that bike had a pretty epic crash, that would have destroyed any wheel.

I think the one picture with the red circle is one with the more easily replaced hub so you can buy a hub and use them on another bike. The factory Ducati ones probably have the hubs permanently fixed. I really don't think the factory swingarms or wheels are unsafe. I guarantee Tom Cruise has several superleggera's. Killing Tom Cruise (or one of his riding buddies) by faulty wheel would be an ugly experience for Ducati. The regulatory folks and more importantly, the lawyers, let them out of the plant. They're ok.

Yeah that exploded BST was a RapidTEK not OEM SL wheel.
BST are made using pre-preg CF layup and autoclaved. Your TK are with woven with CF strands and then injected with resin (RTM). I’d trust the TK’s over BST on manufacturing process alone

Given that you like off roading have you considered spokes. Borrani's are nice.

Carbon spokes rotating??? That doesn’t even make sense. It’s ok to be wrong, Andy...
Clearly the exploded wheel isn’t an SL or OG SP wheel. Just look at the angle of the spokes and the hub as Steven pointed out. Also non-OEM wheels also contain BST markings whereas the OEM don’t.

I wonder what would happen if the hub in the rapid tek came loose? It would probably start to wobble and then rip itself apart. Sorta like the picture?

No reason to "trust" anything, its engineering. Pre-preg is used to build very advanced components, it's a very sophisticated product that removes a lot of potential for production errors. RTM or resin transfer moulding is primarily for high production runs and has its own limitations . As I have mentioned many times, you need to understand the material and think about carbon in terms of load paths and tensile strength, carbon has no strength without the resin whose job is to hold the fibres in alignment i.e. less resin and more carbon but no starved fibres = a very light rigid component. Pre-preg and RTM get to the same place from a different angle.
Carbon can be made flexible by altering fibre orientation and density but you want zero deflection in a wheel, the examples shown would have destroyed an alloy wheel but no one goes around with horror pics of alloy failures and demand we go back to spokes. The other issue with carbon (and its not the fibre but the resin) is fire, heat buildup from a dragging brake, if it catches fire you are ....... A carbon wheel wont survive intense point loading and fire, but then again neither will a mag. As for the one wheel changer apprentice mark and the wheel is a throwaway, Ill take them!

Andy, carbon fails catastrophically, i.e it works then it doesn't. In a wheel It does not deform unless extreme heat was involved to soften the resin.

I like the weave + RTM because you can use a continuous fiber and the chance of voids is less because resin gets pulled through the fibers. I did a deep dive on carbon manufacturing when researching bicycle frames. IMO, RTM is better for strength and durability. Prepreg is better for lightweight applications.

To make this REALLY simple and I’ll admit Havnt had the strength to get them but I rode a 2019 v4 and I have a 18v4s his bike was stock, mine, completely loaded with Titanium axle. Titanium fairing bolts, tuned suspension, flash, Titanium Axle nuts, Exhaust and his felt like a 600 if I had to compare. It was completely like I was whipping around a little R6 and cracking the throttle was almost like becoming a rag doll realizing this idiot turns off his TC on the ....... street. I know we are all to ROSSI and TC is for wannabes. Track sure depending on track conditions for me. Theeen I change my own tires with a harbor freight tire changer, with mojo bar and nylon blocks. But just picked up a . Just picked a rabaconda. My 11 year old got it down. Go buy one. Gaurentee if you scratch it you either where forcing a cold tire off the rim or your . Well, let’s be nice, Ill equipped and have to throw away money for an actually fun and relaxing part of being a motorcyclist. Trust me look em up! Rabaconda Street Bike Tire Changer

For that amount of money I'd probably just go with a No-Mar Classic HD.

I just pay 10 to a tire guy at the track while sipping my 20 decaf latte with extra shot of espresso and watching him do the work

That’s all well and good if you’re at a track and there’s a tire guy who only charges $10.
The closest shop to me wants $30 per wheel.
