So I am to do my first fluid change this week.... having never has a bike with coolant before I was wondering what 660 owners uses as their preferred fluid (pink or blue or green).

I'm going to flush the system completely it currently has blue - non OAT fluid (pink)

but any advice greatly appreciated

if you choose to use OAT coolant then flush your system properly and dont mix with ordinary coolant, i think OAT is recomended for 5yrs use and ordinary for 2 yrs use , other than that not alot to choose between them :beerjug:
 
Why not buy the Yamaha branded stuff that you know is right for the bike?
 
I had to swap coolant bottle on mine last year before going off roading in Spain so took the opportunity to flush the coolant out. (Common fault, people mix bolts up and pierce coolant bottle)
Probably went overboard but flushed everything out with water, including removing radiator to clean out the fins. Then used flushing solution and rinsed out again and refilled with Comma branded OAT mixed 50/50.
Glad I did as it was regularly over 35°C's.

Yamaha genuine coolant has recently changed from red to blue.
Just use the genuine new blue stuff.
