Have you seen these prices???

On the other hand, they don't generally cause any problems, and I think the Braking waveys are cheaper than OEM. (mine was anyway, so was the Galfer that I killed) The rear disc actually is lighter btw, but that's more because the rear OEM disc is very simple because they couldn't care less how heavy it is, because nobody will notice the difference). So leaving aside whether it's a performance mod, if you think they look good there's no big reason not to IMO.

I've got wavy discs on my CBR. The reason I got them is because I warped the OEM ones. The Galfers were pretty much the same price as the OEM ones. I have no idea if they will be more or less warp resistant than the OE ones, but being a tart I thought if I am spending that sort of cash then I want everyone to know.....ergo wavys.

I think they look cool.

They probably do perform better than originals and if your bike is your baby then why not spoil it and put wavey disks on?

I would have em in an instant but unfortunately cant afford them. If its your thing and you like em. Have em. You only live once.

How?? I'm not necessarily against them or for them, but I still can't see how a wavey disc could perform better than a round one. Surely things like quality of materials, weight and manufacturing processes used dictate whether one disc is better than another rather than the shape of the disc itself?

Don't diss Trinny, she may be a ruggy, but she's dead cute with it.

Sponsorship, it's why some top riders wear nasty cheap kit. Money talks in racing.

It's because if you took a plain disc with no features in it, as you use the brakes the surface of the pads become glazed. By adding features such as holes, J hooks, waves etc then you can create an edge that is presented to the pads, this in affect slices the glaze of the pads. Of course, this is the theory bu brakes are a very complicated subject - you need to look at pad and disc compatability, temperatures etc - one of the best materials around for breaking is cast iron, but not very practical for everyday use.
