Those wheels, and later model BST's have a braided wire loop molded into each side of the wheel for rigidity and strength, and don't seem to have any issues.
It was earlier model BST's without those that breaking problems seem to happen with.
Sweet Spot setup is 540 lbs

It'd probably be cheaper to hack the engine into a different bike's frame, rather than all the cost weight reduction addiction...I mean, we steal enough stuff from the R1...why not just pull out their engine and slap ours in! 
I'd love to drop 50lbs off her, but the price of rims and an exhaust alone equal 1/2 what I paid for her

I find the quest for weight loss to be interesting...and a good hobby albeit an expensive one.It'd probably be cheaper to hack the engine into a different bike's frame, rather than all the cost weight reduction addiction...I mean, we steal enough stuff from the R1...why not just pull out their engine and slap ours in!

My brother who has an BMW RT found the 'ol Bumblebee to be very light.....a neighbor who used to have an S1000RR M found it to be a big heavy whale....
I must be one of the few Hayabusa owners that doesn't care about weight or think the bike is to heavy, from my perspective and riding style the bikes weight is a plus and not a minus. I've noticed a heavier bike feels more planted and doesn't get blown around as much in cross winds or when you pass a larger vehicle coming from the opposite direction. I do understand some riders are looking to increase performance and weight loss contributes to that goal but I'm satisfied with the bike as is.

I agree with you. I like the weight of the Busa just like I did on my Blackbird I owned 17 years ago. There's something reassuring about that kind of heft and substance. Like a well made knife. Lightness has its place of course but I'm not lapping Laguna Seca battling Biaggi and Hayden.

^that's why I bumped up from my 600cc. I would've never even looked for a bigger bike if I wasn't riding on the interstate everyday.

It's been done, Busa engines into Gsxr750 and 1k frames, but it takes a skilled fabricator who can tig weld.
I would love the Busa engine in a Gsxr1k, as the bar reach is shorter.
I also agree that the Busa weight can be a plus, as it is more planted.
1k vs Busa, both with proper suspension setups, and the much lighter 1k is going to dance around more over bumps and on rough roads.

All that being said I do want to get lighter wheels (Core Moto) and probably do the 520 chain conversion with an aluminum rear sprocket. The static weight doesn't bother me. Rotational weight you can really feel when tipping the bike into a corner and flicking from side to side. Plus those wheel just look cool as poop. Never mind they save you 8.3lbs static which once it's rotating is more like 20lbs.

Sure, especially riding fast when the wind gets gusty enough to notice or even slow you down a little.
But I also really doubt 540 would be too light for you.
I agree 540 wouldn't be to light for me but I'm not willing to spend the time or money in order to get there :-(

Took my Busa with the twisty setup for a perfect hour loop yesterday, and right before I watched a YouTube video.
It was a review of the new Porsche 911 S/T which I guess is their new super stew of best parts and costs over 300 Grand. But is apparently one hell of a great sports car to drive. And the similarity between the reviewer's happiness at driving the ultra sports car was EXACTLY the same way I felt about my lightweight gen 3. The exact same emotions. So maybe that car is the four-wheel equivalent of a gen 3 setup for twisties.
I've decided that public roads are no longer variable. There is a set speed limit over which it's simply dumb to ride. Too much gravel and too many idiots behind the wheel in my experience. Now that speed limit is still quite fast as multi-inertial ABS braking can let you avoid worst case scenarios coming around the curve. My familiarity with my gen 3 is now high enough that I can basically ride quite fast and comfortably at about 95% of that speed limit, and doing so is exhilarating and fantastic. Vehicles in front of you are little more than trees you can slide around with a little work, and they tend to pleasantly bunch up so that once you get past them the road is yours.
And I really don't care if the busa is 25 years old. The way I am riding, I don't want 200 horsepower and 90 lbs of torque. I want that 110 lbs effortlessly pulling me away from every apex, on tires with so much grip (Bridgestone s23s, 36lbs cold in the rear, 34 in the front) sometimes the engine lifts the front tire and moves it over a foot inside the turn for you. With electronics set at 1 out of 10 that keep the rear from spinning. More power than I need on tap at all times. Saw Jeremy Clarkson also on YouTube say something that really resonated recently. He was doing some track comparison with Richard Hammond and said, about lap times, "If you've got more than 500 horsepower, you don't drive as quickly. It doesn't make sense but it's true." I've also recently seen similar comments about Cobra builds. The amounts of power that are available now exceed what you will really ever use or want. I'm not so sure that's not exactly the current state of sport bikes.
Granted I wouldn't mind riding something with a modern V4, but I'm so happy with my 1340 unit it's only a mild curiosity at this point. Look at the happiness of this guy. EXACTLY how I felt setting out on my ride. Everything letter perfect and more than you need. I didn't know you could be this in love with a motorcycle!
*+1 rear sprocket that you could argue about but I would say I did notice the difference (just slightly shorter gearing).

The Ohlin's racing webpage says that would be over $4,000, but wouldn't be their electronically controlled semi active system. I would absolutely love to try the electronic package should it become available, but don't want to spend that much without the electronics and don't really have it anyway. The BST carbon wheels were pretty pricey and I don't have any budget left. Maybe we'll get that Öhlins’ SmartEC3 system available as an aftermarket system in the next year or three. I'll have to think about it then. I am heavy and on the far end of the spec for the stock springs and shock, but I've had them tuned by a pro and frankly the stock suspension feels pretty damn good if not perfect. I can't imagine how it would be better, but I'm sure Ohlins would be an improvement...
* I thought about the Penske shock in the rear just for weight reduction but do want to hold out for a whole new system. If I have the money...

Wrong brand. BST do not use a wire. I wouldn't buy them if they did. The whole point is that the wheel flexes when it hits something then returns. A wire would get bent and stay bent.
They did not originally, but do now

Yeah I just called Brock's who I bought my BSTs from. They have no idea what you're talking about. I don't either. Wrong brand. I wouldn't want a wire in my rim. It would get bent as it's less strong and less flexible.
Braided wire cable doesn't bend, it flexes, andit gives the rim strength and something for the cf to bond to.

On an auto or motorcycle rim, it better flex exactly the same way as the carbon fiber wrapped around it, or it's going to be a bad idea. And it's going to do that on some brand other than BST.
Rotoblox does it, and when I spoke with Bst a few years ago, they said their new design was going to use the same, which I see they have yet to do
