[Manga]

The radial calipers are so named as they are mounted radially to the forks, instead of conventionally. The mounting offers less chane of the calipers twisting around the forks/discs. So I suppose you could get a good setup with just the calipers.

I have a radial MC off a GSXR if you cant find one for sale.

Bas*ard...

Need to re-read Shazaams! stuff now to get a grip on the correct ratio to be using as well.

Manga, cheers - might well be looking for an alternative soon.

Yep, I just noticed that as well, wish people would not pull auctions when there are bids on the item

Im in the Piemans camp here, Less brake--More gas. we dont need silly brakes,just means we have to be savage on the gas out of corners cos we slowed down to much

See what this season brings. might have to eat my words -)

Good luck at the Hairpins then

Frank is upgrading his road bike brakes I believe.

Howdo!

I fitted a set of 848 forks and radial 4 pad calipers to my Superlight and a Brembo radial M/C.................. The bike has V strong progressive braking, couldn't ask for more. Works in town as well as from 160+ (Closed road don't want to upset the fun police).

M/C is definitly the way to go to get the best from the brakes. Me GSXR is a cracking bike apart from the brakes, as soon as I've sold me other kidney it's on the shopping list!

Cheers Pablo

Frank,

The Supersport (and 748, Chris) brake master cylinder is 16mm and is not a good hydraulic ratio match to the Brembo 4 pad calipers. The 749/999 radial master cylinder is 18mm and would be a good choice— any 18mm actually.

Radial pumps actually don't offer better stopping power, so a conventional 18mm unit will also work well.

Yep, found that out, that is why I converted a set of 749/999 radial master cylindrs to use with the P4 calipers I fitted to my 748, as per the thread that I posted a few years ago about the conversion that Ant kindly relocated for me fter I failed to find it .

BTW, if the 749/999 is a ratio of 18mm, what is the ratio of the latest 1098/1199/Penigale master cylinders?

18mm diameter (same as the 749/999), with a 19mm piston-fulcrum distance (don't remember what the 749/999 distance is).
