Quarterpounder I get you just don't like them but they are a great Quality item. Most would be pleased with their purchase.
I too am a service Tech. I change Bearings for a Living. I did not feel the need to mention, but ok
A couple of pics
This bearing weighs 345lbs and takes 19 tubes of grease
Shaft once bearings removed
I think most would be pissed off that they dropped 350 on bearings just so there bike pushes easier in the garage, we installed them and seen no et in the 1/4 or mph worth even talking about. maybe in lsr they might give a little mph but i but nothing worth talking about over the bearings QP is talking about. if I get to the point where I need my bike to push easier in the garage I will stop riding.

Of course if they push much easier in the garage or staging lanes, they also reduce rolling resistance when under power....which is the advertised feature, right? Ceramic bearings are not something you install expecting a huge gain; they are just one of many small details that can add up to a measurable performance increase.
Now I am going to run out and buy a Goldwing...because real mean don't want a wimpy bike that pushes around easier in the garage!

The biggest problem that occurs that I see in a regular basis is the steel roller gets hot when used hard and expands. This expansion pushes the grease to the out side seal. This Now burn't grease becomes stiff over time & remains stuck to the outside edge of the seal, there for does not get picked up to lubricate the roller. The Properties of the grease change with pressure and heat. The inner race tells all.
Ceramic roller resists heat, so Expansion(the trouble maker)becomes a none issue, there for keeps the grease soft which allows it to perform the job it was meant for. By not getting pushed out or burning the lubrication properties of the grease resist change.
The Ceramic Bearing is a superior product in every way, just cost a pretty penny. I know it's not for every one but I don't mind because I think there worth it .
It was that or a 500 dollar Skull painted on my gas tank lol.
Just sticking to the point they are not a Gimmick,, maybe just not worth it for all . Cheers

you don't even come close to the performance envelope that they are capable of....so the issue of heat on a bike is a total non issue. If you are getting hardened grease or the bearing is getting that hot in your wheel, you got other issues going on.
I've never said I didn't LIKE them...they work great for the intended purpose they were created.
My whole deal here is based on the OP that is using these for STREET application, and for a typical street application, you can get very similar performance for MUCH less (as shane also said) with a good steel ball with non-contact seal and poly cage. Why spend 300-400 bucks when you can spend 100 and not be able to tell the difference in a street application?? If you are uneducated on it, you'll just read about it from internet hero's with no better knowledge other than "I read about it or my buddy runs them" bull shit. I am trying to educate the OP that he may not have to spend that kind of money and he could save a few bucks along the way now that he can make an educated decision. Most have zero clue about the options or make up of a bearing. Simple item, but very precise and lots of engineering goes into them. I stand by my comment that ceramics are a gimmick for street use....if I were selling ceramics, dang skippy I'd be pushing them. LOTS more money to be made. You would be sick if you saw the markup on bearings.
roman, I mention that I am a field service tech for a BEARING MANUFACTURER so you know that the info I am giving is not just some opinion formed from reading about it on the internet. Rather, it's from actual work experience and professional KNOWLEDGE along with personal experience from using BOTH types of bearings. Excuse me for validating my information that I am giving.

"Gimmick For Street Use"
I guess no point in asking you what you think of BST's wheels for street use lol ? Turbo's out ? Big Bore Kit ? Nos ? Air Shifter, What about a ZX-14 with 200 rear wheel horse power ?
None of the above you will get the Most Out Of In Every Day Street Use, but some of us Love them just the same. I can appreciate any & all performance upgrades, but I hate gimmicks. Implies I was lied to and got ripped off or was about to. And,,, it has happened. more than once
Im now thinking my way of looking at what a Gimmick is, is much different then yours is all. Gimmick = will not deliver what they promised. Fake, Fraud , Flat out lied in the description.
Ceramic bearing may not be for everyone one due to there cost but they are sweet upgrade just the same. 300 is chunky and hard on the wallet,,,, but it's our bike ???? Worth it,, you decide.
Qp, I'm new to this site I will be happy to tap out of this one. Sorry if I offended any one, that's not my way. Cheers.

Gimmick is getting someone to pay 300 bucks for very little performance increase over something you can get for 100. Just sales bullshit IMO. So yes, in your terms, they do not deliver IMO that much more performance if any for the street. I doubt you could tell the difference if given blind testing.
And as for BST's, THE best mod you can do for the handling of your bike...just can't stomach the cost involved. I'll just make due with better suspension and learning how to utilize all it has to offer. 200hp for the street is stupid...can't even use it. Dragstrip...different story. Hell, it's hard enough to maintain the restraint and concentration it takes to keep things fairly sane on the roads most of the time.
You've totally gotten me wrong and what the original point was.
