New bike

BN, what exhaust are you getting for UK TD's?

The 'blade demonstrator I rode before buying mine had a Racefit on it too and it was very rude to the point where I could see it attacting unwanted attention, even with the baffle in.

I'd be keen to know if there is some sort of nice middle-ground between the whisper-quiet standard fit and something like the Racefit.

Make sure its nice and tight to the swingarm or you will ground it out on right handers

My Akra had a gap and it would scrape

Nice bike. What is the advantage of wavy discs? My 250 had petal discs, but they were more form over function

Personally, wavy discs are purely for looks IMHO, but still, they do the job.

Blades are good track bikes.

In race terms, they disperse the heat faster and its less MG of unsprung weight.

But none of the race bikes in 2014 had them? BSB/WSB/Motogp?

Thats because if you run Brembo calipers, you run brembo discs...

Muckle pisstaker hew.

Nice can.

[RemyMartin]

Mmm racefit.

If wavy discs were that good Brembo would use them!

I think that says it all really.

[mckeann]

I'm sure at us mere mortal pace they'll be fine.

[mckeann]

I ran standard homda discs with better pads and it was great.

Just make sure the can is quite tight to the swingarm or it'll scrape.

Oh well, I'll throw them away.

I'm sure they will be fine, but at the same time I'm fairly sure they won't offer any advantages over the standard discs other than looking good

I have Galfer wavys for my R1. They are superior than the standard steel discs I have, using the same pads. Tend to use Galfers on my dry and the standard on the wets

I get the second point about weight... But how do they disperse heat faster?

You've reduced the total metal in disc. You've also probably reduced the total contact area with the pads as well, and the overall surface area to metal ratio is actually reduced, if anything they should run hotter?

Am I missing something bloody obvious again?

No, because each brand has an identity.

Brembo have T drive 'Gold'

Galfer have waveys

PVM have slash cuts

etc etc.

Think it was Kawasaki who provided a study a few years ago showing there tests on stock waveys vs stock rounders, that showed faster heat loss etc. One of many.

But still, i digress, its pointless talking about it.

Perhaps (just perhaps) the wavy outer edge profile being longer than a simple circular circumference, as well as the slashes and such allow the core of the disc to cool faster rather than just the surface. Maybe. So the entire mass of the disc is cooled rather than just the two external surfaces.

Or not

Or maybe it doesn't generate the same amount of heat to begin with since there is less surface area on the friction material.

But as brakes need friction to work, less area means less braking power, no?? Maybe any loss of surface area is mitigated by better thermal properties and looking really awesomely cool?

But as brakes need friction to function, less area equals less braking, no??
Or maybe the slight loss of surface area is mitigated by the better thermal dynamics and looking really awesomely cool.
Brembo T drives are designed to conduct more heat away from the friction face and into the rotor hub for better cooling.
