Motul makes great products. Here is another 1....
MoCool Radiator Additive is a non glycol base additive and legal for all road racing applications.
Adding this product to straight water or an antifreeze/water mix can reduce your cooling system by as much as 30 degrees F (15 deg C). This improves heat transfer and increases performance. It reduces corrosion and is compatible with coolants.
This is a 500ml bottle of concentrated fluid you mix at 5% with water.
If you race your water cooled motorcycle on just about any track around the planet then you already know that using anything glycol based is an absolute NO-NO....... This is an excellent option to use with water to help keep your engine cool.
