Triumph coolant not available

I think if you can get the Honda coolant it will be compatible.
 
Have you ridden in extreme temperatures....either below freezing or above 100F?
Yes i have been caught out below freezing, and out in some crazy heat and never had a problem, keep in mind that is on a 2010 touring, for the GT i will have to see if that is even compatible or I will have to use a different option
