hi, anyone got a "recent" link and/or recommendation for sintered pads for an 89 851 Race bike please? cheers

Hope your using stainless discs. Cast iron is machined by sintered pads. Stop unbelievable well but. I tested them out on a couple of warped discs.

did it unwarp them?
griff851
I had the warped rotors surface ground first. They were close to limit after the days fun.
The feel and effect was very much like a radial master cylinder and radial calliper set up, pulled up mind blowing well. So much I remember thinking, race discs, one race meet, one set of discs. Expensive!
I changed the cast iron discs with some new ones I scored, but the centres were old and were just about shot. I got a few rides out of them before I found another complete set that were near new.

i think the ferodo cp911 is a popular race pad. never used them, i think they're something other than sintered.

The Ferodo CP911 organic pads were great pads for use on cast iron rotors. They were the only pad that I would use when I raced in the late '90s. Very kind to the rotors and great grip with good modulation. They only took about a lap to heat up. I used them on my street bikes as well.
They were replaced by the CP911 Star,which were replaced by the CP1 and now the latest organic race pads are called the C-Pro. I have not used them, but considering how good the CP911's were, they have got to be good. They have graphs that show much higher coefficients of friction over all temperature ranges

If you want a sintered pad for use on stainless racing rotors, then the Brembo Racing Z04 pad is the best available. It is what is used by most World Superbike and World Supersport teams. They are very pricey, ($300-400 for a set) and may not be available for early calipers, you will have to do some research.

I agree with Brian on the Z04's - used them on the track for many years-- great feel and linear control.

thanks Gents for the info. I may have to revisit use of Sintered on 851.

Dan, I may have over exaggerated on the a set of disks, per race meeting. I did the Rathdowny, Graville, Lyons rd circuit at a politically incorrect pace, with some lunatic mates. I was thinking you would probable easily get a season in vintage racing, particularly this year as it's panning out. Only three due to the lakeside situation. If you get an after market set of cast iron full floaters, and right them off like tires, you'll have a major advantage over the field. It's not WSB and your not going to be pumping out 140Hp and suffer heat fade etc, and I would image the FZR's would be using stainless and sintered pads. They may out accelerate you, but are heavier!
There are some crazy arse stuff going on in the name of racing in hysterical racing. A good example was a 500 Pantah. The discs were drilled out to the point i'm sure there were more holes area than disc rotor area, done for weight reducing, by a bloke that seemed to have his act together. Worked well for a bit. Then the disc gave way, locked up the front wheel,and 3 Pantah's went down, one hospital visit.
The point being, pay attention to the disc width limits and simply out brake the field, it's not illegal, podium finish.

We use these on the IoM MCB540SRQ TRW Motorcycle Brake Pad
