I always changed my brake/clutch fluid on the bike every 18 months, yes, that much humidity and in my car, every 2yrs ... As well as coolant, NO exceptions ... Yes, avg humidity 70% and those seals in MCs, just don't trust them, I have just replaced my car's brake reservoir's cap on last fluid flush made.
Interesting. Melbourne's summer has had tropical humidity this year and a very high dew point. The customer's bike was sweltering in a tin shed. Might have to change to Panama specs.
