Not really brand specific in my opinion and a small amount to fill your whole system up is not the element that break your wallet so i try to get the proper (toxic green color) cooling liquid (cost here about $8 a liter and does OK for my bike).

alright thanks.. if you had coolant in your bike could you put some water in as well or would that be bad for the bike ?

If you're just down on coolant, you can add water to it.  Distilled water is best, but faucet or tap water can be used too. Just note that if you start diluting the coolant with too much water (beyond ~70% water) the anti-freeze properties of the coolant will be reduced.  So if you store your bike outside over the winter and temps get below freezing, you need to be mindful of that

The amount you need to fill up a motor bike cooling system is so small that it would not gain you so much money in the wallet (so why bother) if water have to be added go with distilled water or RO water only ( still no guarantee for the PH level (you want to have pH 7(neutral)) of the water that could also attack your cooling system internals) all other water contain elements and salts that could leave deposits or a film layer what affect the cooling adversely or it simply attacks the metals (little bit of salt will eat in aluminum (pitting)) Robert-Jan   1996 Honda CRM 250 (sold) 2002 Husqvarna WR 125
