For those that have fitted the Motobatt hybrid, did you just swap over the batteries as you normally would? A cursory glance at the instructions makes it look like there's some nonsensical procedure.
D’WFR is a June 2023 1250. Battery dead by March 2025! That includes Optimiser charging once a month over Winter.
Not sure why everyone seems to think that a drop sensor is the same as a battery...
Your bike does have a tip over sensor. It disables the bike. It's under the seat.
Remove it and give it a shake. Then try again. I've never opened one up but usually they're a ball bearing or a weighted rocker switch.
It could be stuck!!
I've never seen this fault code due to a low battery. But there is a first time for everything I suppose.

Mainly due to
A the lack of the OP mentioning that he’d dropped the bike, (so I presume he hadn’t)
B the fact that drop sensors pretty much don’t fail, and
C the second fact that if you’ve got a useless battery, you get all sorts of nonsense displayed on the screen.
D the third fact that the batteries from that time were shite, and the bike won’t start.
It sensed a voltage drop, hence drop sensor lol.
I faulty drop sensor wouldn't need a bike to fall over to sense a fault. Hence faulty.
I agree they rarely fail. But every electronic component has a failure rate. I have replaced faulty drop sensors. Maybe 2-3 in the last ten years on beemers.. So it's clearly not impossible.
There are a PLETHORA of faults that SHOULD supersede his fault if he has a useless battery.
You could be right. It might be a voltage issue. It could be the battery. But firing the parts cannon before any attempt of diagnosis is not the way to fix anything. Especially when a battery is so expensive.
A diagnostic scanner costs half as much as a battery.
For my 2021 bike, it was a straight fit, no changes required. Definitely a better battery and solved my poor starting issue. Been in the bike a year or so and no issues with it at all.

Cheers.
I’ll bow to your experience but I’ve never seen or heard of such a failure.I faulty drop sensor wouldn't need a bike to fall over to sense a fault. Hence faulty.

I have, however, been mightily fucked about by my bike, in all sorts or bizarre ways, because the battery was useless. I changed the battery, and my GS is now reliable. I haven’t had a single issue with idiotic messages on the TFT since the replacement. In fact, I haven’t had an issue with anything.
Prior to the simple battery replacement, the bike has had the alternator replaced, two other prolonged dealer visits, repeat issues with the SOS system, and I can’t remember how many “just won’t start” issues, usually when just warm. I can’t remember how many call-outs. It was an utter fuck-up. And despite the number of people who knew, it wasn’t the bloody tracker! After all these issues, I even wrote to the uk head office, to no avail, “it’s a dealer issue”.
And then I thought “fuck it, the GSER collective suggest a new battery, its £100, just do it”. And I did. Abra-ca-fucking-dabra.
So I have passed it on. You might have a better idea. His bike isn’t my bike, it could be a different issue. But as a starting point, I’d replace the battery.
Loop the sensor out, then try it still the same it's not the sensor. Electronic circuits for modern car/bikes can and do throw non related codes when another part fails or is failing. Many DPF cars will throw, ABS, glow plugs codes when it's the DPF, for example. Also run the bike off a power supply via the battery, if there's no issues. Disconnect the power supply and run it again if there's issues it's the battery.I faulty drop sensor wouldn't need a bike to fall over to sense a fault. Hence faulty.
