Honda does not make antifreeze.
Don't know who makes it but when in doubt stick to OEM.
Silicates are actually scrubbing agents that scrub the inside walls of everywhere fluids go. It is a terrific thing except on plastic and seals. It will also scrub the plastic thru if given long enough.
As for alternatives, Prestone extended life is silicate free. My 96 Silverado has the very same requirement.
Your bike, you decide.
