I last changed the brake fluid on my 2017 Gen 3 (with ABS) in December 2021. Yesterday I thought I'd check the condition of the fluid out of curiosity. The moisture level was still below 1%, which is still well on the safe side. The fluid is just Comma DOT4 (£6 a litre from the local motor factors), nothing special.

I do around 11 to 12K miles per year on the bike and while it is garaged, the garage is not heated and is a bit draughty. It shows that in the UK climate, even basic brake fluid can last well beyond the usual recommendation to change / flush every 2 years.
