I use WW for the track... Mixed as directed on bottle w/ distilled water. I've run WW on some of the hottest temps at the track you'll ever find (Willow Springs in dead of summer). WW performs well & keeps engine temps in check. WW is required of many tracks, b/c if your bike leaks std radiator fluid, it will leave a dangerous slick on the track surface.

While I usually switch back to Pro Honda HP Coolant 50/50 premix after track days, at one time I ran WW all summer (wide temp range) b/c I had track days back to back. It performed as well on the street as it did on the track.

 

If I lived where it never got below freezing,I would run WW and distilled water year around. I believe WW has the corrosion inhibitors in it already.

 

Correct. It does. Any extra added (50/50 premix) is for additional protection & is recommended by RedLine for street vehicles/use.
