qaisar Posted March 23, 2004 Share Posted March 23, 2004 Ive seen those for bikes before and were supposed to be quite effective, also saw them for cars and thought about getting a set, so would also like to know other peoples, such as CW's, views on them Quote Link to comment Share on other sites More sharing options...
BigRoy Posted March 23, 2004 Share Posted March 23, 2004 I've had these on supermoto's and superbikes. From that the verdict is that they are very pretty;) Oh and expensive:D But the OE discs performed better. The pretty discs just eat pad's.

jagman Posted March 23, 2004 Share Posted March 23, 2004 Hmmmm... I cant see that these would be well balanced,how would you balance these things? 1 or 2 grams out at one of the tips? -wibble wobble.Never seen these before,I wonder why Quote Link to comment Share on other sites More sharing options...
michael Posted March 23, 2004 Share Posted March 23, 2004 The way I see it.... Less disk = less pad contact Less pad contact = less friction Less friction = less brakes I don't even think they look pretty Quote Link to comment Share on other sites More sharing options...

qaisar Posted March 23, 2004 Share Posted March 23, 2004 Well looks are a personal thing and in my view they look good in that they are different from normal. But BigRoy seems to have experience with these sorts of discs and if they arent an improvement on OE and are in fact worse then theres no point.

womble Posted March 24, 2004 Share Posted March 24, 2004 Hmm, I remember a few years ago when these started off on bikes. At first it was on off roaders and the supposed benifit was less gyroscopic effects due to lighter weight (a big thing on a crosser with 21 inch wheels), cooler running temps and less mud clogging due to the increased circumference. They've been available for aftermarket fitment now for a while for most popular road / sports bikes and Kawasaki (regarded as pretty good engineers) have been the 1st (as far as I know) manufacturer to fit them as standard at production on their flagship model the ZX10R which is a serious piece of kit.

Ian C Posted March 24, 2004 Author Share Posted March 24, 2004 Er, that bike brake looks nowt like the stuff on Ebay? Not sure what your point is there... -Ian Quote Link to comment Share on other sites More sharing options...
outatime Posted March 24, 2004 Share Posted March 24, 2004 They look like one of those 'fan' weapons you see in martial arts films. I can't imagine they do they brake pads much good? Where the contact supposed to happen? I wouldn't have them anywhere near my car Quote Link to comment Share on other sites More sharing options...
Adam W Posted March 24, 2004 Share Posted March 24, 2004 The bike disc looks like corss-drilling/venting taken to the extreme. The wavy discs look like stupidity take to the extreme Quote Link to comment Share on other sites More sharing options...
albundy68 Posted March 24, 2004 Share Posted March 24, 2004 cant be good for braking, but they do look pretty cool! Quote Link to comment Share on other sites More sharing options...

Less disk = less pad contact Less pad contact = less friction Less friction = less brakes I don't even think they look pretty Force applied through friction is independant of contact area. The torque applied to a circular face had more to do with the coefficient of friction between the two surfaces, load pressing the surfaces together and the mean radius at which it is applied. However, you need a large area to dissipate heat, and spread contact pressure so that the mating faces don't wear too fast. As for balancing, you could in theory balance each one individually by drilling one well-calculated hole in the hub, but I can't see anything that looks like a balancing hole and I bet it would all be too much bother for them to do.

neilg Posted March 27, 2004 Share Posted March 27, 2004 Just to stick a bit in, I put some of these on my old rover coupe turbo (rotordisks) had the bigger brake conversion on it anyway (from a honda prelude) and going from standard honda disks to these made improvements. Try them! Quote Link to comment Share on other sites More sharing options...
Darren Posted March 28, 2004 Share Posted March 28, 2004 I come from a Moto cross background and thats where the wavy disks originated they are now OE fitment on KTMs and the techies say ACTUALLY have a greater surface area and give increased breaking..All the factory teams are running them in MX too...Not sure about the car version on Ebay they look a bit bling...HTH Quote Link to comment Share on other sites More sharing options...
dude Posted March 28, 2004 Share Posted March 28, 2004 I had the wave discs on my Aprilia and they were a defo improvement in braking on a bike that used only on track !! Dude:flame Dev Quote Link to comment Share on other sites More sharing options...

If they are better at keeping cool then under prologned braking they will be better. The main thrust of the shape seems to be to aid the circulation of air to this end. Also, they claim to induce greater friction through the grooves, so you would be putting a lot more heat into the pads, which would have to be dissipated. So t'would appear that if they work it is because they are more friction-y (tehch term) and are better at disspating heat. Quote Link to comment Share on other sites More sharing options...
Halo-Inc Posted April 27, 2004 Share Posted April 27, 2004 If there were any advantage don't you think Brembo and AP may have designed a similar disc? As for the looks..... Quote Link to comment Share on other sites More sharing options...
