Thanks to all. See my avatar ;) I am used to having excellent brakes, and on the subject of speed costs money, the engine build for my turbo Busa land speed bike was over £12k more than a decade ago.
I’ll see how I feel about how a change of pads to Ferodo Platinum in a stock system works firstly. If the difference is too marginal then I may just bite the bullet and go for a different set up.

Considering what you’re used to, I personally doubt you’ll get satisfaction from different pads etc, but do keep us posted, it’ll be interesting to see what you conclude.
 
The conclusion was quite quick actually.

I was in conversation with Don , Madass140, and he has delivered to me a 320mm floating disc, with bracket and 6 pot Tokico caliper that I started to fit today. From order, at the weekend, posted on Monday and delivered today Thursday - 4 days from the other side of the world. Yet a pair of pads ordered a few days earlier still haven’t arrived from a UK seller.

I put on a 13mm master cylinder, and had the chrome taken off the disc. Stock caliper and pads. It is plenty to lock up that skinny front tire.

Yes that sounds more than adequate. Never really understood the obsession for one-finger pull brake lever action or dual discs on a light, road going bike. If you can lock the front with minor mods to stock, thats all you really need.
 
Ability to lock the wheel isn’t really the best measure of a good brake. I can lock the wheel on my pushbike, but I won’t be fitting rim blocks to my motorbikes !
 
I tried racing with a single chromed disc with a Lockheed calliper. I tried various pads but it was hopeless. I now have two Lockheed callipers with asbestos pads and two steel discs and a master cylinder which usually only operates one calliper, but now does both. The brake is one finger and excellent. For racing, it has to be like that. For a road bike, some guys seem to get by, by dragging their foot on the ground.
 
EBC pads magura 13mm master one piece ss braided line stock caliper rebuilt with ss pistons drilled RGM disc iworks great for me or did i say that before?
 
Re. brake discs. I (currently) have a Norvil 12" 'floating' disc on the front. It is the type that has a splined centre to fit on the standard 5 stud front hub.

Is the RGM 12" disc a better option? different disc material etc.

I have a CP2696 (Lockheed) alloy caliper, with 36mm pistons, the type that Triumph used for twin disc kits. It has AP LMP123 brake pads, is there a better / more suitable option?

The master cylinder has been sleeved down by RGM.

CP2696 calipers are alloy the 4 rib replacement for the CP2195 3 rib period race calipers and have 41mm pistons, if you have 36mm pistons you have something else. Triumph used a heavy cast iron caliper, some of which I think may have had different size pistons!

I race with these calipers and have used various pads, mainly EBC sintered GPFX, which I find most effective, they stop well but may be a bit brutal on a cast disc.
 
The cast iron calipers have 41mm pistons. They weigh a ton.

The alloy 36mm calipers look exactly the same as the 'racing' caliper, they do have a secondary dust seal around the piston.

I had a look at the EBC GPFX pads, the EBC website says 'race use only' so maybe best avoided for road use. But they do have other sintered pads for that caliper. I will have a go with some of the FA016HH sintered pads, got to be worth a try...
 
Not news but the reason for beefier brakes isn't to lock the front wheel but to provide reliable braking power after repeated hard use something the stock
pads cannot do. This has been discussed.
 
Quite. I could lock the front wheel with the original caliper if I pulled the lever hard enough.... it is a matter of 'feel'. And when I pull the lever on my bike, despite all the alterations, it still doesnt feel like I am slowing down much...

And better feel. That is SO important.

I use EBC EPFA pads on the front of my Duc, and HH pads on the rear. They are excellent pads. I wid not hesitate to use HH pads on the front of my Norton.

Also your solution to the Brembo caliper and the mudguard stay is a lot neater than the CNW solution of an odd looking loop the loop bend.
