How many miles when you changed your brake rotors and what type of riding did you do (in reference to brake usage)?
How many sets of brake pads did you use before you had to replace the rotor?
What went first the front or the rear? OEM or after market? ST1100 or ST1300.

Let's collect some data ..

Thanks
 
I have not replaced rotors yet. I have 52k on my present st1300 but I am now at 52k on third just installed set of brakes. I had 65K on previous st1300 and did not change rotors .my rear brakes always wear faster than front, but I always replace front and back at same time
 
Don't think U'll find much Data to collect on this question/ST brake rotors. LOL
250K on an ST1100 here with original rotors. Always used Honda brakes that gave great mileage & performance.
And NOW 100K miles on the ST13 with original rotors - have no idea when they'll wear out !

Agree there may be little data available. 58,000 miles, brake pads 1/4 worn, rotors excellent due to 99.9% long distance highway riding and incredible engine compression for braking.
 
A friend of mine had to change his rear rotor at about 158 000 km. It was under the wear limit. Still running the front. He does a lot of city and 2 up.
 
Changing all mine at 167k on ST1100. Lots of 2up, sometime I pull a trailer. Several sets of pads, currently using EBC HH. The EBC pads are harder on the rotors, but I like the feel.
 
My 1991 ST1100 I bought with 16k miles and sold with 69k miles. Changed one set of Honda pads front and rear, rotors front and rear were fine. Mostly two lane riding and I was not a heavy braker at the time.

My 2008 ST1300 I bought with 14.7k miles in April this year and changed the front and rear pads at about 26k miles, rotors were fine. I have EBC HH front and Honda rear. I have no idea how the PO rode so no data on the first 14k. I ride this bike different than my 1991 and have started to use the brakes more and in a different way than in the past. We will see how they wear.

I am using the front and rear more together than on the 1991. The 1991 was mostly front.
 
62,000 miles. Rotors are still good. On my third set of oem brake pads.
 
changed my front rotors at around 100k miles, they were down to 4.00mm. After OEM wore out, I tried one set each of EBC HH & Galfers pads. I commute mostly, and a short commute at that, so my braking per mile ridden is probably higher than most on this forum.
 
There are a number of riders on this forum that have over 200k miles on their bikes. If none of them replaced their rotors then that is useful information.

I have 62k miles on my ST1300 and just put on my fourth set of brake pads. So I got ~20K miles per set of OEM pads. The thicker rear brake pad wears out first, the fronts had about 30% of pads left but I just replace them all each time. From what I have read here the front rotors are 5mm thick and the rear rotor is 7mm thick. They should be replaced when they loose 1.0mm (at 4mm and 6mm respectively). Using a metric micrometer my front rotors have lost 0.18mm and the rear has lost 0.40mm. A little math means that I should have to replace my front rotors at 344k miles or after 17 sets of front brake pads and the rear rotor at 155k miles or after 8 sets of rear brake pads.

In retrospect, I now realize that, since I have linked brakes, I always used just the brake pedal and rarely use the front lever. This may be why my rear rotor and pads are wearing faster. Going forward I will now try to use both brakes evenly, had I done so I could have gotten an estimated 250k or 12 sets of brake pads per rotor. Averaging now will yield less.

Now I commute every day 72 miles round trip. About 1/3 the time is city stop and go driving / lane splitting. So I maybe harder on my brakes than someone who just goes on long non-stop trips but maybe less hard than one who is peg scraping on a tail of a dragon all the time.

It would be still nice of you high mile riders to tell us of your experience and thanks to those who have already posted here.
 
180,000 original rotors all around in fine shape. I didn't check but I think I'm on the 4th set of front pads. I hardly ever press the rear brake pedal. This data will not mean much, guys with high mileage bikes could ride all day and use the brakes maybe 10 times all day.

If train leaves Chicago doing 51mph and an ST1300 leaves Dallas headed the same direction doing 62mph..... :D
 
Don't waste your money or time.... My '05 has 184K (Justin now rides it and it still has the original.)
 
Don't worry, the data collection is on a grant paid for by the gov't
(like most of the usless surveys done by them) :)

Any evidence or data to support this idear?

I got nothin' scientific, but a lot of Vulcan owners in the early 2000s had trouble with premature rotor wear after switching to EBCs.

Same with Valkyrie riders. And if I remember right ST1100 and Valks have the same front disc or was it rear disc?
 
126k miles, will be replacing all three on my ST11.
Year round, 120-180mile/day mostly dense traffic highways, 2-10 miles lane splitting, cruising speed outside congested areas 75-90mph.
Not sure how long a set of pads last but with the salted roads in winter time I do experience some caliber binding every now and then causing additional wear.
 
170K on St1300. My rear rotor needs replacing now. I hear metal grinding before the pads are actually worn out. The noise is coming from the brake pad backer plate coming in contact with the lip at the top of the rotor.
