The coolant for motorcycles needs to be non-corrosive for aluminum heads. Most of the time, its not just your standard yellow crap. I use water wetter and there are many products like water wetter that when mixed with de-ionized water, make a great coolant. Especially in texas, you don't need something that works in low temp's.
Yep. Everybody's right. The VW stuff is the red colored type which ORIGINALLY signified safe for aluminum heads IIRC. Now you need to read the bottles. The green/yellow stuff is many times marked safe for aluminum too.

The vast majority of car engines are aluminum now days. I use plain old Prestone 50/50 in everything from my aluminum bike engine to my aluminum truck engine. Aluminum is aluminum whether it's powering a car or a truck or a motorcycle or a snowmobile...no differences.
Stay away from mixing anti-freeze with de-ionized water. The DI water is very corrosive, which is why it's usually found in PVC pipes. RO water (reverse osmosis) or distilled water is better than tap water.
The biggest difference between the green and orange anti-freeze, IIRC, is the recommended length of time between changes to maintain corrosion resistance. If anybody is going to analyse a material to death, it would be Honda or BMW. Both of their anti-freeze solutions are blue in color (silicone based?) and probably more expensive than a gallon of something from Wall Mart.

It's not just a Ducati, it's a disease!
de-ionized water is not corrosive in itself (unless you mean relative for use in a car battery)
It is run in PVC pipes because if you run it inside of cast iron or galvanized pipes it will re-mineralize. (for lack of a better word) which will defeat the object of the exercise
reverse osmosis is a process where a purer form of water is obtained, but it still has lots of minerals and ions in it.
The purest from of water is distilled water which has just about zero minerals and ions in it (which makes it good for preventing scale buildup in an engine but bad to drink for humans over the longterm.)
Whatever you do, never drink antifreeze - it will destroy your liver and it is a slow and agonising death.
