Dear friends, I too fell into the trap and bought a Quality Coolant That Is Not suitable for our CBR250R motorcycle, and not suitable for motorcycles at all. I am from the old generation, in my time anyone who wanted to invest in a quality coolant bought a special green liquid, and did not settle for ordinary Distilled-Water (and extra thrifty people filled tap water).
Gentlemen, the OLD G11 standard based on the active ingredient SILICATE is not suitable for motorcycle engines that made of aluminum(Like our CBR250R), with a radiator that is also made of aluminum.
For CBR250R, the G12 standard, or G12 +, is suitable, and G13 is also just that G13 is more expensive.

According to the Honda manufacturer's specification:
The active substance should be of the Ethylene Glycol type, and preferably in a concentration of 50% active ingredient compared to distilled water.

And there is also a short video I made about draining coolant:

Coolant Type

Hi guys. After adjusting my valves, I removed the radiator, and thus half of the coolant, in order to have enough room for my elephant hands to get through the frame bars. There seems to be a slight oily type film on top of the coolant I saved in a pouring cup. Not sure if it came from the...

colour of dye used in coolants has nothing to do with corrosion-inhibitor additive package. Read up on coolant types here: Engine Coolant Basics

YES. I did not buy the wrong liquid because of the green color, I bought because I intended to buy a professional coolant (compared to: distilled water, or tap water), I did not know there was interest with an aluminum motor or radiator.

The paint is just a pigment that manufacturers add to differentiate coolants from the same company that are different types of active ingredients (Different properties, for example G11, G12, G13). There is no standard for the color of the liquid and every manufacturer can choose a color as he pleases.

I just picked up a 2 qt. bottle of Coolanol Motorcycle & ATV Coolant at my local bike shop for $15. Ethanol, pre-mixed, easy-peasy.

Yes, not a complicated maintenance job, just I did not know there is a special interest with aluminum, I thought it was a professional coolant, more expensive more better, compared to, distilled water, or tap water.
So yes, the coolant should be from Good Qualit, and include in its specifications at least one of the following:

• "Suitable for Motorcycles"
• "Suitable for aluminum engine"
• "Based on Ethylene Glycol"
• "On an Organic basis"
• "G12 or G12+ standard"

Usually at least two of them appear on the coolant packaging. And of course the percentage of the active ingredient, and if you need to mix in Distilled-Water, or the ingredient is Ready-To-Use (I bought a ready-to-use coolant).
