There's pro's and con's to different brands like anything else; but anything that is labeled safe for aluminum should work just fine for your bike. Most antifreeze is these days as I understand it but for peace of mind I wouldn't run anything not specifically labeled somewhere as "safe for aluminum engines".

I buy mine at the local auto parts store my nearest Kawasaki Dealer is an hour away. The Shop Manual for my Mean Streak specifies as follows:
Permanent type antifreeze ( soft water and ethylene glycol plus corrosion and rust inhibitor chemicals for aluminum engines and radiators)
Soft water 50% coolant 50% -35 C (-31 F)
You may want to get a shop manual for your bike as changing coolant in my bike evolved a bit more that just draining and replacing the antifreeze. That being said the dealer estimated $180.00. I bought a gallon of premix and have enough left over to add as necessary until the next change.
For peace of mind and at the expense of a couple bucks, I just buy the Honda coolant. Premixed and ready to go. Yes there are cheaper ways to go, but, I change it out every other year and the dollar cost isn't going to break me.
