Sooo...

I am in the market to purchase some ceramic wheel bearings for my 2011 ZX-10R. Does anyone have any recommendations which brand I should go with, along with price? I'm also looking to see if anyone has experience with using ceramic bearings on OEM wheels. I would look into lighter wheels like BSTs, etc. But, I don't have that kind of money.

Any input is greatly appreciated!

Hybrids use a steel outer and inner race with ceramic balls. They offer improved fiction over normal bearings at a lot lower price point than full ceramics. Full ceramics will set you back close to $500 versus $300 something for the hybrids.

Interesting. I'm guessing for these to be this expensive, they must be pretty effective. lol

From my understanding, full ceramic is made more for vacuum environments,MRi machines, and things like that. but thats probably grade 25 to 100

grade 5 is the strongest of them

If you get a set, be sure to get a set that specifies quality on the seal. BC alot of ceramic failure is due to debris and cheaper seals. I dont know to much about them, but the white ceramic is suppose to be brittle.
I use to rewind/restore electric motors with my dad. From single to really big 3 phase. we tried using ceramic bearings in our pumps, bc we hoped they would hold in a wet environment better. However the sets we tried disintegrated under pressure (these pumps where very very hard on any bearing, requiring constant change and maintenance)

Really though, this was years ago, and im sure the motorcycle specific bearings are probably grade 5 and top notch-in seal protection.

The Largest amount of friction in bearings comes from the grease

EDIT Im interested in this also now and going to do some research myself. Bearings are something easy to change and when i need a set i may try this. I called my dad and asked him if there was an update on bearings he uses in the pumps. He told me the pumps have been reworked with new units, and he has been using full ceramic in them for a while now. He also said if it wasn't for cost, he would put them in the oil rig motors also. But those guys want them as cheap as possible. Those pumps and motors work 24/7 rain, sleet, or snow

My input; these bearings are quite sensitive to any contamination. They are used quite a lot in bicycles (high-end stuff) but require frequent maintenance and replacement. The sealed ball bearings in your bike are of excellent quality and will give very good service for years. If you want to play around with this by all means, but realize the trade-off in slightly less friction is offset by a much less robust bearing overall. This application is for machines that can be serviced frequently and fairly easily (pumps, bicycles, and so on), not for vehicles like motorcycles that are ridden for years and need to be reliable under a wide variety of conditions (dirt, dust, water, snow, hard usage).

I appreciate the input. But, they make ceramic wheel bearings specifically for motorcycles I believe.

I have the world wide ceramic wheel bearings. They work great, but the bearings alone won't make a huge difference.

Everyone always hates on me when I say this but super-light wheels and bearings don't make a huge difference; At least in road racing. Now I'm not saying you won't notice them....just that I'd have everything else like suspension and geometry dialed in before I bought some couple hundred dollar bearings. I've had BST's, marchesinis and a set of OZ wheels with worldwide bearings in all of them...no failures.

The ones we spoke about this morning are the Worldwide bearings for reference. Great reviews on the product.

You got it! I spent a fair bit of coin on transmission and wheel bearings and it did NOTHING! Bike gained no mph anywhere.

Stay away from the ceramic bearings man. Unfortunately you would be just wasting your money like I did lol.

Yes, they sure do. I wasn't saying they were only available for bicycles, just that for your motorcycle you probably won't realize much of a change, and the sealed ball bearings that come with the bike are much more robust and tolerant of contamination. But if you go for it, let us know how it works for ya!

Yikes. Not what I wanted to hear. :frown: They must work though if they have good reviews and are $400, right?

Gotcha. Sorry, I guess I read your post wrong. lol

Definitely notated. My bike is lowered 2" in the front and 1.5" in the rear. I also have a Gen.1 Hayabusa front fender on the bike. As you can probably tell, I like to do top speed runs. lol

Thanks, Mike! I think your free shipping is what will seal the deal if I decide to go with them. I'm just having mixed thoughts now based on some of the reviews with not making much of a difference. For $400 that doesn't seem too practical. :dontknow:

If you had a race team and were looking for that one hundredth of a second, then yes they are worth it. However for you and me, not worth the coin at all. I am dead serious they did absolutely nothing. I did some 70+ passes last season at the track and there was no improvement in mph lol. Not until I dumped in MR12 lol.

The amount of actual power that it takes to spin your wheel bearings is minuscule. Since there is not much drag there to begin with, there is not much to be gained by reducing it.

1/100 of a foot-pound of torque (estimate, probably high!) x 1000 rpm (in this range of road speed) = 0.002 horsepower ...

In a conventional (steel) ball bearing, most of the drag is from the seals and viscous drag from the grease. Let's say for argument's sake that half the drag is from the seals. If you really want that 0.001 horsepower then just buy shielded bearings from the bearing shop rather than full-contact rubber seals. BUT, life will be shortened because they are not fully sealed against water and dirt getting in, and lubricant getting out. Note: Ceramics are not tolerant of contamination and have to be sealed also. If the seals are the same then the drag will be the same ...

On my roadrace bike ... I use plain ordinary double contact sealed bearings from the bearing supply shop. Stock wheel bearings are only sealed on the outside. Using the double sealed bearings means less risk of contamination getting in when the axle is removed (e.g. for tire changes). The lower risk of trouble is worth the 0.001 horsepower in my case.

I appreciate all of the info. Since I am having my bearings removed for powder coating purposes, I was considering the ceramics. Is it true that I can't re-use my current OEM bearings/seals in the bike once they're taken out?

Yes, it's true. They are pressed into the wheel hub using the outer race. But to extract them, they have to be pulled out or beaten out using the inner race. That transfers the load through the ball bearings to the outer race and will deform the races and balls slightly. If anyone tells you they can get the bearings out and you can reuse them, they are full of shit.
