I have a racing bike. I've heard other racers using ceramic bearings in their wheels but not in their engines. Im based in Singapore btw.
In certain places yes. What ever bike you are a racing in Singapore will not NEED ceramic bearings so I would not worry about it.
Don't waste money on ceramic bearings, they won't be of any benefit and that would show in your lap times being the same regardless of what you use. There is nothing wrong with well lubricated metal wheel bearings so spend your money on something that will make a difference to your racing like better brakes, better suspension, a mod to the motor, something positive .....
Sure can and any of the better riders will have them in their bikes as they produce less friction. A company called Black Mamba have them Just goes to show how outdated some peoples advice can be as I could list any number of professional riders who use ceramic bearings in their bikes as they do make a difference. In the here and now a standard crf250r is around 36.5 on a dyno and to make them competitive they need to become at least 43. The ceramic bearings make the bike rev up quicker and smoother and any person who is a dyno specialist can tell a bike that has ceramic bearings in it just by that alone. So it does make a difference. Oh and thanks for the thumbs down mr B and I must say I just loved your answer to the 6ft tall guy who has a klx125 and you told him that it was the best bike for him to start racing on. I can just see a 6ft tall guy turning up to a mx track on his kiddies bike and finding no section to race in and being laughed out of the place. Perhaps you should ask Chad Reed if he runs ceramic bearing as I know the answer to that one. The question was also can you run ceramic bearings, not should I.
