whats the purpose of anti-freeze? & how do you use it on a motorcycle in the winter?

Anti-freeze keeps water from freezing at 32 degrees F. If you have a water cooled bike, you mix the anti-freeze with the water to keep the bike from freezing up and bursting.

Most modern liquid-cooled bikes use a 50:50 mix of anti-freeze and water. But they don't use it in the winter they use it all year round, the mix cools better than water alone and does not corrode as quickly.

If it's an air-cooled bike, you don't need antifreeze.

If it's water cooled, antifreeze is necessary to prevent the water freezing and rupturing the radiator, pipes or cylinder block (water expands on freezing). Follow the user manual for correct types and ratios of antifreeze to use.

Anti-freeze is part of the cooling system and not to be used 'on' the motorcycle but instead 'in' the bike.

It stops water frrezing and you mix it with radiator water so your coolent system does not die
