2023 r1250rs intermittent fail to start?

[Grumpy Goat]

That’s happened to me a couple of times, starts and then immediately cuts out, but then starts again fine. My bike even cut out mid ride this year whilst changing gear, was luckily on a downhill straight, and it fired up again whilst on the move. We don’t have winter fuel but have wondered if it could be due to using standard fuel rather than super.

I have used Regular AKI 87 when on long multi-day rides and have had zero issues with performance or starting. I typically put the Midgrade 89 AKI in the RS. My issues with the summer blend (double start after a cold soak, e.g. first thing in the morning or leaving for home after work) is not octane dependent.

When batteries have died on my RS they have gradually gotten weaker until they fail to turn over. Never have I had a hard start and then a robust start, but I guess it is possible and attributable to a defective battery.
