Coolant 50/50 premix

Question...

I have an '02 vn750 w/9000 miles on it.
Before putting the bike up for the winter, I changed out the coolant (First time) and refilled it using PRestone 50/50 premix. The bottle says safe for all aluminum engines.
However, it doesn't say its silicate free. I checked the Prestone website and there isn't much info about it (only dexcool appears too specifically say silicate free).

Do I have to worry? Can I drive with it for the upcoming year, and change it out again next fall w/o any issue or concern?

Or, do I need to change it out with dexcool silicate free coolant?

Thanks,
Dom

By the way, the Prestone 50/50 mix I used was the 5/150k UNIVERSAL mix.
(Safe for alluminum engines).

Thanks for any advise on this.

I contacted Prestone about this.
They stated that their Universal 50/50 mix (as well as full strength) coolant is in fact SILICATE FREE, and is safe for all alluminum engines!

They stated that older Prestone (non-Universal coolant) may or may not be silicate free. In older bottles, if it states it - it is. If it doesn't - assume its not.
