How do I winterize a motorcycle?

Updated October 2026 · How we answer

Step-by-Step Winterization

Start by washing and drying the motorcycle thoroughly to remove dirt and road salt, which can cause corrosion. Then, fill the fuel tank to the top with fresh gas and add a fuel stabilizer to prevent gumming. Run the engine for a few minutes to circulate the stabilized fuel through the system.

Next, change the engine oil and filter to remove contaminants that can damage the engine during storage. Remove the battery and store it in a cool, dry place, or connect it to a trickle charger to maintain its charge. Inflate the tires to the recommended pressure and consider putting the bike on stands to avoid flat spots.

Finally, store the motorcycle in a dry, well-ventilated area away from direct sunlight. Cover it with a breathable motorcycle cover to keep dust and moisture off. If you can't store it indoors, use a quality cover and elevate it off the ground if possible.

• Wash and dry the bike
• Fill tank and add fuel stabilizer
• Change oil and filter
• Remove or trickle-charge battery
• Inflate tires and use stands if possible
• Cover with breathable cover

Long-Term Storage Tips

If you're storing the motorcycle for more than a few months, consider fogging the engine with fogging oil to protect internal components. Also, plug the exhaust and air intake with clean rags to prevent moisture and pests from entering. For carbureted bikes, drain the carburetor float bowls to avoid varnish buildup.

Check the coolant level and antifreeze concentration if your bike is liquid-cooled; ensure it's adequate for freezing temperatures. Lubricate the chain and other moving parts to prevent rust. During storage, try to start the bike occasionally if possible, but avoid short runs that can cause condensation.

• Fog the engine for long storage
• Plug exhaust and intake
• Drain carburetor bowls (if applicable)
• Check antifreeze concentration
• Lubricate chain and cables
