coolant?

[MissTwisties]

Today I did an oil change, change filter, check brake fluid (good), check coolant (too low), tighten chain and lubed it, check bolts, and tire pressure.

Man God says I can put any type (brand) of coolant in the bike...I'd like to verify this with you guys? (2005 Ninja 500)

Just make sure it's safe for aluminum...
