Why Winterizing Your Motorcycle is Non-Negotiable
The decision to properly winterize your motorcycle is an investment in its longevity, performance, and your peace of mind. Neglecting this crucial process can lead to a host of problems:
-
Corrosion and Rust: Moisture, especially when combined with temperature fluctuations, can lead to rust on metal components and corrosion in the fuel system and electrical connections.
-
Battery Degradation: Batteries naturally self-discharge, and cold temperatures accelerate this process. A completely drained battery can sulfatize, freeze, and crack, leading to irreversible damage and premature replacement.
-
Fuel System Issues: Stale fuel can degrade, forming varnish and gum deposits that clog carburetors and fuel injectors, leading to starting problems and poor engine performance. Ethanol in fuel can also separate, causing corrosion.
-
Tire Damage: Leaving a motorcycle parked on its tires for extended periods can cause flat spots, compromising handling and requiring tire replacement.
-
Pest Infestation: Small animals and insects can seek shelter in exhaust pipes, air filters, and other openings, potentially causing blockages or chewing through wires.
-
Fluid Degradation: Old engine oil can become acidic, and other fluids can lose their protective properties over time, leading to internal component wear.
By following a thorough winterization checklist, you actively prevent these issues, ensuring your motorcycle remains in peak condition and is ready for immediate use when the weather warms up.
The Complete Motorcycle Winterization Checklist
Here’s a detailed, step-by-step guide to properly prepare your motorcycle for storage:
Step 1: Thorough Cleaning and Protection
A clean bike is a happy bike, and this is especially true for winter storage. Dirt, grime, and road salt can cause corrosion if left on surfaces for months.
-
Wash and Dry Thoroughly: Give your motorcycle a comprehensive wash with mild soap and warm water. Pay attention to hard-to-reach areas where dirt and grime accumulate. Rinse thoroughly and dry every surface completely to prevent water spots and rust.
5 -
Wax and Polish: Apply a good quality wax or polish to all painted and chrome surfaces. This creates a protective barrier against moisture and oxidation, keeping your bike looking shiny and new come spring.
5 -
Treat Leather and Vinyl: Clean and condition any leather seats, bags, or trim with a suitable leather care product. This prevents cracking and drying out in cold temperatures.
1 -
Lubricate Moving Parts: Lubricate all cables (clutch, throttle), pivot points (levers, footpegs), and locks. This prevents seizing and ensures smooth operation when you bring the bike out of storage.
1
Step 2: Address Fluids and Fuel System
The fluids in your motorcycle are critical for its internal health during storage.
-
Change Engine Oil and Filter: This is one of the most important steps. Old engine oil contains contaminants and acids from combustion that can corrode internal engine components over time. Drain the old oil and replace it with fresh, clean oil and a new oil filter. Run the engine for a few minutes to circulate the new oil before shutting it down for storage.
5 -
Check Brake Fluid: Inspect the brake fluid level and color. If it’s dark or discolored, consider flushing and replacing it. Brake fluid absorbs moisture over time, which can lead to corrosion and reduced braking performance.
2 -
Check Coolant: Ensure your coolant level is full and that it’s the correct type for your motorcycle, providing adequate freeze protection. If unsure, consider a flush and refill.
-
Manage the Fuel Tank: This is a point of debate, but generally, there are two main approaches:
-
Fill the Tank (Recommended): Top off your fuel tank completely with fresh, high-quality gasoline. This minimizes air space inside the tank, preventing condensation and rust formation. Immediately add a fuel stabilizer (e.g., Sta-Bil) to the tank. Run the engine for 5-10 minutes after adding the stabilizer to ensure it circulates throughout the entire fuel system, including the carburetor or fuel injectors.
5 -
Drain the Tank (Less Common for Modern Bikes): Some older carbureted bikes might benefit from a completely empty fuel tank and drained carburetors, but this can lead to dried-out seals. Consult your manual if considering this option.

Step 3: Preserve the Battery
A healthy battery is essential for a quick start in spring.
-
Disconnect or Remove the Battery: Disconnect the negative terminal first, then the positive. For optimal preservation, remove the battery entirely from the motorcycle.
-
Store in a Warm, Dry Place: Store the battery in a warm, dry location, ideally above 32°F (0°C). Extreme cold can damage a discharged battery.
5 -
Connect to a Battery Tender/Maintainer: This is the most crucial step for battery health. Connect the battery to a smart battery tender (not a traditional trickle charger). A battery tender monitors the battery’s voltage and automatically switches between charging and maintenance modes, preventing overcharging and ensuring the battery stays at an optimal charge level throughout the storage period.

Step 4: Protect the Tires
Preventing flat spots and maintaining tire integrity is vital.
-
Inflate Tires to Recommended Pressure: Inflate your tires to the manufacturer’s recommended pressure for storage, which might be slightly higher than riding pressure. This helps prevent flat spots from developing due to the bike’s weight resting on one section of the tire for months.
5 -
Lift Tires Off the Ground (Highly Recommended): If possible, place your motorcycle on a front and rear stand (or a center stand if equipped) to lift both tires completely off the ground. This eliminates pressure points and prevents flat spots.
5 -
Rotate Tires (If Not Lifted): If you cannot lift the tires off the ground, periodically roll the bike a few feet every few weeks to rotate the tires and prevent flat spots from forming in one area.

Step 5: Protect from Pests and Moisture
Small creatures can cause big problems during storage.
-
Plug Openings: Block the exhaust pipes with steel wool or a rag to prevent rodents from nesting inside. You can also cover the air intake.
5 -
Protect Wires: Mice and other rodents are notorious for chewing on electrical wires. Consider using rodent deterrents or placing mothballs around the bike (though be mindful of their strong odor).
-
Use a Quality Motorcycle Cover: Cover your motorcycle with a breathable, indoor-specific motorcycle cover. This protects against dust, dirt, and minor impacts while allowing moisture to escape, preventing condensation buildup underneath. Avoid non-breathable plastic tarps, which can trap moisture.

Step 6: Choose the Right Storage Location
The environment where your bike is stored significantly impacts its condition.
-
Dry and Warm Space: Ideally, store your motorcycle in a dry, temperature-controlled environment, such as a heated garage or a dedicated motorcycle storage facility. This prevents rust, corrosion, and damage to electrical systems, fuel, and leather from moisture and extreme cold.
5 -
Consider Storage Options:
-
Garages: Your own garage is convenient, but ensure it’s dry and consider climate control if temperatures fluctuate wildly.
1 -
Metal Sheds: Durable and weather-resistant, offering good protection against snow and storms. Look for insulated options with climate control.
4 -
Portable Tents/Shelters: Easy to set up and offer protection from elements, suitable for temporary storage or if you’re transporting the bike.
4 -
Self-Storage Units: A more expensive option, but ideal if you lack space or need climate-controlled indoor storage. Ensure the unit is secure and offers climate control features.
