This is what I use. It is an HOAT coolant which is what the early Rockets called for. I imagine the new ones would use the same.

PS. The color of the coolant usually doesn't mean anything (unlike the old days). The make up of the coolant determines if it can be mixed, not the color. If the base coolants are the same makeup but different colors, then good to mix. Otherwise I wouldn't.

Yep the Gen 1 Rockets called for HOAT coolant, but I think you'll find (well, I did anyway) the Gen 2 uses OAT coolant, so not the same.

Mine has the orange stuff, so will need to flush to use the green

My gen 1 Rocket III I have been using the Blue Honda coolant for years. Since I now have a "22 Tiger 900 and "22 Bonneville T120, I decided to use the Triumph OAT coolant in these 2 bikes. These 2 bikes don't take much coolant, so why not.

According to the Owner's manuals, both the first and second generation Rockets require the same coolant (HD4X Hybrid OAT coolant).

Everytime I see it take OAT I think of Oat milk lol. Maybe some oat milk for coolant, see how that goes.

Yep, my error it does say that indeed. It also says it's green & installed at the factory. Mine is red (redish) and it's never been changed. When I do the coolant flush I'll be using distilled water & Red coolant, same as it's got now. Each to their own.

My coolant is also red in my 2025 rocket.
