Replacing Lithium with AGM

Mines a CRF1000L 2019 and I don't think it came with a lithium battery. Did they change the spec at the end of the model year. I bought mine in March so it was probably made at the end of 2018 (but it's definitely the upgraded 2019 model with Throttle by wire etc)

update - I checked my owner's manual and it is indeed a lithium battery. It seems Ok at 4.5 years and 42k miles, but I seem to remember last year in winter it wasn't ok and I stuck my Accumate Pro charger on it overnight. 😱 No explosions and it seemed to do the trick

As i already wrote and pointed out few times the only good alternative to the OEM 18-24 battery is : Aliant YLP14
Well worth knowing that Ghostrider. Sportsbike shop have them for £138 which is quite a bit better than the honda oem at £530. Could you explain a bit more why you have concluded that they are such a good alternative?

Back on using AGM batteries in a bike built for Lithium, I think its worth mentioning the fires surrounding Lithium batteries being linked to incorrect charging. Now, I am not sure if the voltage regulator is set to different voltages, but I would be really careful when hooking up an external charger. Luckily, you are moving to the safer of the two battery chemistries, but i would research the voltage regulator settings, or you may end up with shortened life span. Throw any Lithium charging equipment in the bin.
But surely the voltage regulator would only come into play while the bike was being driven. Hooking up an external (old style of course) charger to the replacement AGM battery would be completely safe surely? If you had any worries you could take the positive wires off the battery and then connect the charger (or take the battery completely off the bike).

Lithium battery’s need to warm up in cold temperatures before being used. I turn my ignition on get all gear on, turn on comms, etc., then after 40 seconds to a minute it will crank like it’s 70 degrees instead of 20 degrees Fahrenheit. I routinely ride in sub 20 degrees with heated gear plugged in a the stock battery is just fine. The appearance of slow cranking and “lack of cranking power” is a procedural thing.
Interesting - I will try that as I have noticed that if I haven't ridden the bike for a couple of weeks in cold weather, it's slow to crank.
