Sure. They're a handy guide to a bike owner having as close to zero taste as makes no odds.

Re: Have you seen these prices???
 

So the superbike teams who fit them to their race bikes do it because they have no taste, then?

Have you seen the colour schemes on those leathers?

Trinny & Susannah would have a fit!

Trinny and Susannah need to look in a mirror:D

Instigator - that's a weird place for them to crack. Did you often 'cook' the brakes and how did you run the new discs in? A crack in that position looks like a lack of heat treatment after machining.

I've seen a catastrophic failure of a brake disc on our race car, but this happened due to a design error and failed through the bobbin. Now that was messy.

Wavey discs tend to be used for weight saving and pad cleaning (glaze breaking). Holes in dics exist for the same reasons. A lot of brake discs also have J hooks machined into the surface for pad cleaning. Weight can be a big issue as not only does it affect the gyroscopic nature of the front end, but also reduce the unsprung mass of the system allowing improved suspension performance.

Well why are the braking ones (reputable firm) making waveys then? Or could northwinds results have been influenced by the state of wear of the discs.

+1 about that, they must be cutting costs by not stress relieving them.
You get what you pay for.

Only way to get decent quality from the dinks is to be over there constantly supervising (every 2 runs at least), or employ someone in country otherwise it just goes downhill steadily.

Because they can sell them for a packet. Braking have also launched aftermarket wheels which are heavier than the OEM items they replace, they've all about the bling.

Re: Have you seen these prices???
 

So they just look good and aren't likely to crack up and kill you, fair enough if people will buy bling don't blame them for selling it!

Re: Have you seen these prices???
 

I don't ;) Had a set myself, they were perfectly good discs and cost about the same as OE. I just don't buy into the hype. I think the OE SP2 discs I was using last were better discs overall frinstance... But they're so DULL!

The Braking wheels are a bit cheeky though, because a lot of people do market them as a performance part when they're nothing of the sort. But they look mint.

Re: Have you seen these prices???
 

There's a simple litmus test for the world of aftermarket parts: As long as there's still a market for coloured bolts, there is proof that there are motorcyclists with marginally less taste than a bowl of unsalted porridge. Ergo, wavy discs.

When I bought my 7R, years ago, the seller repeatedly pointed out great modifications like bright red braided hoses and the wavy rear disc.

"But what does it do?" I asked him.
"It's a wavy disc!"
"Yes, but what does it do?"
"It's... it's a wavy disc!"

Quod erat bleedin well demonstrandum.
