I have seen "pink"

 

ok so I haven't bought a new bike in 10 years. when did they start doing this

A lot of coolant manufacturers adding red or blue dyes to it to make it easier to see if you have a leak.

 

yup, mostly a safety thing i think... engine ice is BLUE in the bottle, turns green when its effectiveness has reached a low and needs replacing... its written on their site

 

Engine ice is blue but I doubt they used that. Though it would be awesome as that is approved for track use

 

The bike comes with glycol based coolant and you need to change it if going on the track.

 

it comes in many different colors. pink, blue, orange, green. all the colors mean a different level of protection

 

What are the different levels of protection VS colour then? We need the info! :smile2:

 

The dark blue coolant is super hard to get out as it's very blue dyed. and even though I flushed the system twice my water wetter for the track looks blue still. Going to have to flush a couple more times and throw more expensive water wetter at it.

 

The colour is just a dye that means nothing from a performance point of view. As others said, it's just there for leakage detection and there is no world or national standard for this. The only important thing to remember (if you do change your anti-freeze) is to never mix ethylene based and propylene based anti-freeze. They might not mix well. Again, the colour of the anti-freeze DOES NOT tell you which one you have got.

From a performance point of view, ethylene based anti-freeze would be considered as the "better" one but also as the more poisonous one.

 

Yamaha makes a racing coolant if you guys didnt know. and its blue.

Ive personally seen 2 different bikes puking that engine ice coolant on a ride after a hard flogging. Both riders quit using it after that.
