Okay, so 10 months. It should be tested every 12 months and flushed as needed. So, the dealer was probably right that it needed changing again.

Guys…. The poster’s original post stated that it’s only been 2 weeks and several thousand miles since his brake fluid was changed!!

No way his fluid went to 3% moisture in 2 weeks of riding!! If it did, I suspect he would have major brake related issues… which he did not state he had.

No way freshly flushed brake fluid gains 3% moisture in 2 weeks in a sealed system.

okay, slow down y'all and take a deep breath. first, he didn't say he had it done two weeks ago, he said he's going on a trip in 2 weeks. also, the brake fluid should be changed whenever it gets saturated with water, regardless of the time. per the manual, the moisture content should be checked at every 5k service. i bought a moisture meter and check mine every time. i did not make it to 2 years before it needed changing. i had it changed at 10,000 miles, which correlates to 18 months of riding. (usually average 10k per year, but this last year was not normal).

in the end, it's up to you to decide your comfort level. do you want to wait until after your trip and check it again, then have it done? or just pay the $175 and have it done before your trip so you are sure you've got fresh fluids before you go? if you wait, it isn't like the bike is going to explode if it hits the 4% threshold during your trip.

Absolutely normal IMHO. Change every two years or when it is 3%. Under the conditions you list and the time frame, totally possible and better safe than sorry. If you’re worried about dealer taking advantage, do your own maintenance and it will be a non-issue.

Do it yourself. Speed bleeders make it stupid simple.
Go here

and you can do a proper service center flush. Get to where you can change your own wear parts and the dealer won't be stealing any more of your money ... for brakes at least.

Be careful with speed bleeders... I bought a set once (of recommended ones) and had to re-thread the female threads on the caliper and the male threads on the bleeder.
