Hello,
I am the tech manager at Prestone. Couple things, first off, making your bike run cooler completely upsets the factory calibration of the engine. The performance will suffer including the fuel economy and emissions. They regulate the temp to optimum for the engine calibration.
The other issue is corrosion protection. Lots of the "super cooling fluids" contain little or no corrosion inhibitors. A disaster in a aluminum engine. High quality extended life coolant at 50/50 mix is all you need.
