The final word-BST v Carro TriR ---weight
Considering buying lightweight wheels but I am not spending all that money unless I have the lightest--or damn near the lightest if the ultimate in light is 2x as expensive.
JMHO, but BSTs sure look the coolest as far as shape of spokes .
Tri Rs seem like they may be lighter and they are cheaper and they come in a cool anodized blue.
Really what will decide it is WHAT IS THE LIGHTEST????
Please post up if you've done the homework!

I'm sure the bst's are the lightest. On Brocks web site it should say how much they weight.

The Tri-R are heavier than BST's. They are probably not as strong either. They are listed as "race only", I believe.

You bascially are asking Which one is the "best"
Look at what the fastest drag bikes and lancelets bikes in the world are using. Most of them with aftermarket wheels are running bst's. I would take their advice before mine anyday.

TRi R weight ---Weights (Bare) Front 3.50/17 = 6.1lbs
Rear 5.50/17 (8.0lbs) - 6.00/17 (8.5lbs)
They also have a race version but not sure on the weight on those.
Standard GSX-R1000 wheel weights
Front 4.360Kg
Rear 7.529Kg
BST with Aluminium Alloy hubs wheel weights
Front 2.380Kg – weight saving 1.980Kg / 45% lighter than standard)
Rear 4.638Kg – weight saving 2.891Kg / 38% lighter than standard)

They are commonly advertised as almost as light as magnesium. Magnesium wheels are heavier than the BST's. I called them and spoke to them about the weight, over a year ago...they are heavier than BST's.
I have the BST's, obviously. I have weighed them, and the figures Carrozzeria quoted me on the phone were heavier. You have to look at the weight with sprocket carrier, cush drive, bearings, spacers, etc..
They did list those wheels as race-only in the past. Perhaps they were awaiting a certification at that time? Nonetheless, they are nice looking wheels and a lot cheaper than BST's. For $2500 you also get 320mm rotors (14 rotors won't work).

The Tri-R's are DOT approved so plenty strong for the street

I've heard that BST's are a track wheel as are all carbon fiber wheels as they can be damaged by potholes and such. Also the Marvics are advertized as a closed course wheel maybe the same thing also?

Marvics? I never heard of those. Have to check them out.
So looks like you guys are pretty much unanimously giving the nod to BSt for weight. However, I do ride some pretty shabby streets and as much as I try to avoid them, potholes end up getting hit.

Thank you very much for posting weight stats, osr. I am very surprised to hear stock GSXR wheels are lighter than Tri R wheels. I will convert the metric weights you posted above to see how BST stack up. I agree the BST look like Gixxer wheels but that is why I like them. They look like a sportbike wheel whereas the Carros look a little too fancy for my taste. I mean, if they were lightest, I would not let the delicate, elaborate design stop me from buying but if not....?
I will keep watching for new posts. I'm not going to lay down 2-3K$ without digging out all the facts. Thanks very much to all.

I guess strength DOES have to "weigh in" to the equation for me. I can't see fearing doing a wheelie because I might damage a wheel. Not that I do wheelies all the time but when the urge hits/.........you know-.

The stock gsxr wheels are in KG -- so it should be about 2.2 lbs per kg i think. so according to that:
TRi R weight ---Weights (Bare) Front 3.50/17 = 6.1lbs
Rear 5.50/17 (8.0lbs) - 6.00/17 (8.5lbs)
Standard GSX-R1000 wheel weights
Front 4.360Kg =9.592 lbs
Rear 7.529Kg = 16.56 lbs
BST with Aluminium Alloy hubs wheel weights
Front 2.380Kg = 5.236lbs
Rear 4.638Kg = 10.203 lbs
So if those numbers are correct from the various sites -- teh bst front is lighter but the TRI R rear is lighter ????
And yes we do the zx10 conversion kit -- i think it was bout 9lbs total saved over the 14 wheels.

Not quite as simple as the overall wheel weight. Most important part of the wheel is the rim as that most affects the inertia when accelerating, braking or turning. At half the price of carbon the Tri-R is a better bang for the buck but BST's sure are nice. LSL

The Tri R is lighter if you can find a way of running it without a sprocket carrier!
Wheel manufacturers are like politicians.... you have to read the small print very carefully to see what you're going to get.
They almost always quote rear wheels without sprocket carriers and usually give an "example weight" i.e. their lightest wheels. When you enquire about a particular fitment (ZX14 for example) you find the wheel has gained a couple of pound!

Here are real weight measurements I did on my BST's:
quote:
BST's are all about the weight. So, let's see what they weigh:
Front, with spacers:
6 lbs. 1 oz.
Rear, with spacers:
9 lbs. 4 oz.
Sprocket carrier:
1 lb. 13 oz.
Total rear, with sprocket carrier: 11 lbs. 1 oz.
Stock wheels:
Front 11.6 lbs.
Rear 19.5 lbs.
Weight savings over stock:
Front 5 lbs 9 oz.
Rear 8 lbs. 7 oz.
These numbers could be off by a few ounces, but you get the idea.

As stated, the Carrozzeria "bare" weight means no sprocket carrier, no bearings, no spacers, etc.. I researched this way back when the wheels came out (presumably before they could sell them as street wheels).
They seem like nice wheels (I may use a set on something), but definitely not as light as the BST's. As for the 10R wheel conversion, I saved near 8 lbs overall on Racheal's bike, including the switch to a Galfer rear rotor. That is your best "bang for the buck" mod, imo. You may not get a huge MOI improvement, but the weight will go away.

Thanks for setting the record straight, osr. Gixxer wheels are NOT lighter than the Tri Rs.
I am curious about that rear Tri R being lighter than the BST rear. The Tri Rs are listed as bare though---and the BST listed as with alum alloy hubs/wheel weights.

In other words, I don't think you can go wrong. Get the ones you like. A few oz of weight won't be that noticeable on the street.

^^Ya but for what they cost, it is too expensive to NOT get the best and then turn around a year later and wish you did get the best. Too much money to turn around at that point...'least for me. The 14 will continue to see some track use because I don't really go too fast on the street any more. I wonder if a few ounces would make that much diff even for track use. Doubt I would notice it. hem haw, back and forth.....better now than after I buy. lol

I have a busa too. Carrozzeria Tri Rs rear can be swapped over to either busa or 14 using parts sold by Carro to adapt. Front, you need to buy a new one because that won't switch over.
I wonder if BSTs can do that?? NOt that I would think of swapping between on a regular basis but at some point, I will own only one (14 or busa).....and we all know how hard it is to sell aftermarket parts for a decent price. I don't need 2 sets of expensive rims for two bikes that basically have the same performance.

Rook, buddy get the ones you like. I noticed my bike was easier to roll with the BST's but there was VERY little difference in my 1/4 times. I'm sure cornering would have improved drastically but i never tested that theory.

If 8 lbs didn't make a big difference, I don't think you will notice a few oz

LIke i said, cornering may be a whole nother story. But in my bike it made little difference, 8.30 to 8.26.
Imagine paying $1000 per .01... Where's the "sick" smiley?
*I had to edit this..
Keep in mind.. On a mid 9 second bike (typical bolt on bike) a set of wheels will likely drop you .2-.3. Maybe I should have got more out of my wheels? I have no idea. But this was my experience so i felt i should share.
