BMW 2017 Gen 2 S1000R new battery , swapping the OE BMW for a Yuasa YTX9

On the Scotland trip, my battery went flat on Day 3 .

Its been poor for a while now, and Ive been band-aiding the issue by always having it plugged into a trickle charger

Ive always theorised that the issue was the tracker but the tracker company is confident the sleep settings are correct and the device should not cause drain.

Anyway I decided it was time to replace the battery anyway (I still think its the original one supplied from new 2017!) so 8 yrs old.

The original was a BMW branded Absorbant Glass Mat (AGM)  12V 8Ah 12A 

(Note its not a lithium)

replaced with a Yuasa equivalent

Many people fit Lithium replacements as they are much lighter, but my existing charger is NOT Lithium compatible, and I'm not entirely sure the Gen 2 charging circuit is ok with a Lithium style battery (it may be as it appears many have swapped to Lithium ok)

AND

it would appear that later models S1000R moved to a Lithium battery from factory.

Fitting was very simple

Seat off
remove terminals
replace battery
replace terminals
check bike starts

seat back on.

My bike now starts much quicker, but I still have it connected to the trickle charger while not in use.
