I suspect you mean two brake pads per side compared to one brake pad per side calipers, as they both have four pistons total. I have experience with equivalent two and four brake pad linear mount Brembo calipers, and the four pad calipers have a noticeably more aggressive initial bite and a stronger feel all around. The brake pad compounds make a large difference as well. That said, the two pad calipers with good quality "medium" pads should be fine for normal street use. I have to be a little more careful if quickly braking with the four pad model.

I did just check the calipers and you are right Bill: gold line calipers have two pads per side while the grey ones have single pads.
I wish Kev of Norton UK could give us some advise if there is single pads with more bite fitting the grey calipers, otherwise I may go back to my gold line calipers even if they are a bit scratched from the accident...

I have ordered proper "street" pads but I decided to do a little experimenting. I have a small mill/lathe combo and I milled out a 1/2 inch strip of brake pad exactly in the middle of the pad. Each pad has 4 separate "padlets" on it's backing steel. I milled from it's top to bottom equally through the #2 and #3 pads in each. My first low speed trial was good, that initial "bite" was gone and I could use my whole hand on the lever without fear of an endo. Hoping for a ride tomorrow to check it out further.

The two pads per side calipers have two pins or bolts across the caliper body centered on each pair of pads.


Hmm ... my 2015 Sport has the old style?

Contours, you have the exact setup I have.

They suit me just fine. I tend to anticipate and use the engine to brake and hardly ever find myself in a situation that requires me to yank hard on the front brake. A crash in a hard corner at age 19 changed my riding style forever, I'm afraid.

But it is different to the USD version. Don't know if there is difference in braking quality though...

Do I get it right that you have single pads and made two pads by cutting?

I think BritJunkie just cut grooves in each pad with the effect of creating 2 "padlets" for each?

I meant my comment as simply curiosity about the way Norton varies components.

No, all I did was reduce the amount of friction material that was present on each of the four pads.

You can use the brake lever adjustment dial to move the position of the lever. This may help you. If its closer, then maybe you wont want to pull so hard. Another idea is to get the shorty levers. Just thinking out loud here.

My complaint that the front brake had too much initial "bite" for me has been solved with changing the front pads to GOLDfren 141 AD's. eBay has them listed in the U.S. for about $ 32.00 Mark.

Short update: I got the old style Gold line Brembo calipers installed today. What a difference! Apparently they have larger pistons and as stated before two brake pads per side compared to the MkII ones...
Another reason for the bad performance of the MkII grey calipers might be that the set up with Gold line top parts (cylinder etc.) might not fit exactly to the MKII calipers.
Happy again!
