Rotating the rotor without removing the wheel didn't help I think It got a bit worse (tried 3 positions with right side rotor)...

[NervEasy]

After searching the web and measuring the rotors on my bike I found these ones that I am 95% sure will fit:

These are rotors for these bikes:

TRIUMPH   DAYTONA 955i                      955   02-...      
TRIUMPH   ROCKET III                      2300   04-...      
TRIUMPH   ROCKET III ROADSTER      2300   10-...      
TRIUMPH   SPEED TRIPLE 955 i              955   02-...   
TRIUMPH   SPRINT ST 1050              1050   06-...

The have the following dimensions (which I measured on my OEM rotors while on the bike):

outer diameter: 320mm
inner diameter: 78.2mm
offset: 14.5mm
thickness: 5mm
fastener holes: 5
diameter for hole pattern: 100.5mm

Small heads-up, the bolt holes are 10mm instead of 8mm on the OEM disc so you will need M8 shoulder bolts.

Appreciating all the info in this thread 
Regarding the Front Disc Bolt holes;
Parts Manual specifies:
STAR DRIVE BUTTON HEAD SCREW M8X20-10.9

I can't see what the Bolt Hole Diameter, on the suggested replacement rotors is.
Is there a difference (in mounting bolt hole diameter) between the OEM Rotors & these replacements?

[NervEasy]

The replacements will be 10 or 10.5mm. But are in the right place normally. I will let you know what bolts will fit. There are some M8 shoulder bolts (with 10mm shoulder) I have my eye on. Normally more info next week.

On my SR, going for an aftermarket brembo disc completely solved the warp/pulse/thing that was getting really bad. the disc is not an official fit but does fit perfectly anyway, so if you found something that goes nicely on the srs, it has a good chance of fixing the problem !

Which Brembo rotor fits an SR?

Do you happen to have the part number for that? I have the pulsing, and will be replacing my disc.

Hi all,

Just for the record, among all the problem I'm experiencing on my 2020 SRS 5000km (charger replacement inducing SOC/range inconsistency and longer charge time, loss of end of charge mobile notifications, clock not keeping time, remote access to location and status on ios app not working), I'm also having the pulsing problem on the front brake (that's my 11th bike and the first time I get this), and with regen I barely use these brakes.
The rotors dont seem to be warped, as checked by my local dealer. He changed the pads which obviously did not solve the issue. The problem is that for him everything is ok.

For me replacing the rotors fixed the problem…

Quick question, did the charger replacement work to fix the wrong SoC and charge times?

I have had this problem before on the front disc of a 2005 Triumph Bonneville and my 2009 BMW F650GS. I would get pulsating at the lever when nearing a stop, but not when braking at high speeds. When measuring the disc run-out with a dial indicator, there was no indication that the disc was warped. I was told by an old-time mechanic that it was likely due to a pad residue buildup on the disc surface. He recommended using a brake cleaner and plastic scrubbing pad to remove the surface buildup. He also claimed that the buildup was because I don't use the brakes much and when I do i brake lightly. He recommended that I use the brakes harder to prevent this buildup which can cause uneven friction across the surface of the disc.

While that did help for a while, the pulsing returned after a few thousand miles. Naturally, replacing the disc and pads restored the braking feel to normal. But eventually the pulsing would return. I tried several different brands of brake disc and pad combinations and eventually settled on both EBC brand pads and discs. So far that has worked out well for me and I haven't experienced any further braking problems on those bikes.

Getting back to Zero: The problem that I had with the braking of my 2018S was a loud screeching noise when coming to a stop. EBC HH pads totally stopped that issue and braking has been better than with the stock pads. Fortunately, I have not had any issues with pulsating brakes on that bike.


Cleaning your brake disc thoroughly and replacing the pads with a different brand like EBC might be worth a try, especially if aftermarket brake discs are hard to come by.

Thanx Richard,

I'll probably give it a try after one last complain to my dealer (the bike is still under warranty), I'm quiet disappointed, this bike cost me 20k€ ...

Quick question, did the charger replacement work to fix the wrong SoC and charge times?

The original charger reported error 37 at every charge, but it seemed to do the job after all. This behavior started after v18 upgrade. They changed it 2 weeks ago after 1 month delay waiting for the charger to come from US to France. But now, the SOC/range algorithm seems to have changed, my range is considerably shorter (maybe 30%) than before. Before, the range was 180km at full charge, now it reports 110km at start and eventually increases to 140km. Maybe it needs to "learn" and adapt to the battery pack, or they missed to reset something ... I definitely need to get back to the dealer.

Hi all,

For your info, my dealer managed to deal with Zero to change at no cost my front brake disks and pads.
So far, the problem is fixed.

I have a 2020 SR/S and I had the same pulsing problem early on. I just started using the front brake a little harder when coming to a stop and the bike now has 11,000 miles and is fine. My Brammo Empulse with Brembo brakes did the same thing. Try this before you replace the rotors. What have you got to lose?
