Storing Your Motorcycle for Winter in Alaska
The end of Alaska’s riding season always comes too soon, doesn’t it? One week the roads are clear, the next they’re slick with frost. Putting your bike into storage isn’t easy, but proper care now means it’ll be ready to roar when spring returns.
Winter storage in Alaska means protecting it from months of cold, moisture, and darkness. Here’s how to keep your machine in top shape until riding season comes back.
Clean and Protect Your Motorcycle Before Winter
Of course you keep your bike clean, but before winter, give your two-wheeled chariot a full treatment. Grime, bugs, and road salt can damage paint and chrome over time. Wash and dry the bike completely, wax painted areas for protection, and spray exposed metal with a light coat of lubricant to prevent rust. While cleaning, check for leaks or loose bolts so you can fix them before spring
Condition the Leather for Long Storage
Leather needs extra attention during Alaska’s long, dry winter months. Once the seat is clean and dry, apply a thin coat of leather conditioner with a lint-free cloth. Use a non-toxic, water-repellent formula to restore moisture and prevent cracking or fading. Proper conditioning keeps your seat supple and ready for the first warm day of the season.
Choose the Best Place to Store Your Motorcycle
Where you store your bike can make all the difference. The goal is simple: keep it dry, stable, and protected from Alaska’s winter moisture.
Indoor Storage
A dry, sheltered space is ideal. Garages and sheds work well if they stay clean and ventilated. Before covering, make sure the bike is completely dry to prevent trapped moisture. Use a breathable motorcycle cover made from soft, non-abrasive fabric to block dust while allowing airflow.
If your garage collects dust or debris, consider adding a lightweight underlay or sheet beneath the tires to keep them clean. A small dehumidifier or moisture absorber nearby can also help prevent rust and mildew during long storage.
Outdoor Storage
If indoor space isn’t an option, choose a level, raised surface and keep the bike away from runoff areas. Before covering, wash and dry the bike thoroughly to prevent moisture buildup.
Use a high-quality, waterproof, and breathable motorcycle cover that fits snugly around the tires and frame. Many covers include lockable straps, so secure yours with a sturdy lock and chain to a solid anchor point for extra protection.
If your bike is exposed to sunlight, cover the tires fully to protect them from UV rays. Even in winter, sunlight can reflect off snow and gradually dry or crack the rubber.
Position the bike away from melting snow, dripping eaves, and strong winds that could tip it over. With the right setup, your motorcycle can stay safe and dry until the riding season returns.
Change and Treat Motorcycle Fluids Before Storage
Cold weather can do real damage to untreated gas and old fluids. A few extra steps now protect your motorcycle’s engine through months of sitting still.
Step-by-Step: Treating the Fuel System
Follow these steps to properly winterize.
What you need: Fuel stabilizer, funnel, clean rag, gloves
Start with fresh gas
If possible, take a short ride to a gas station so you are working with fresh fuel.Fill the tank nearly full
Leave about ten percent empty for expansion. A near-full tank limits air and moisture.Add stabilizer
Measure the correct amount per the label. Pour it into the tank. Ethanol-free gas is ideal if you can get it.Mix the gas
Gently rock the bike or add a small top-off splash from the pump to help blend the stabilizer.Circulate the treated fuel
Start the engine and let it run five to ten minutes until it reaches operating temperature. This moves stabilized fuel through lines, injectors, and the fuel rail.Extra step for carburetors
After circulation, close the petcock and drain the float bowls. This prevents sticky residue and hard starts in spring.Seal and store
Shut the gas cap firmly. Park the bike on a stand if available to take weight off the tires. Connect a battery tender. Cover the bike with a breathable cover.
Alaska’s cold winters amplify condensation, so a near-full tank with stabilizer helps prevent water buildup during long storage.
Refresh Oil, Coolant, and Brake Fluids
Used oil holds moisture and metal particles that can corrode engine parts. Change it before storage, even if it isn’t due yet. Check your coolant and brake fluids as well. Clean fluids prevent internal corrosion and make spring startup smoother.
Battery Care During Alaska’s Winter
Cold weather and long inactivity can drain your battery fast. The safest approach is to remove it and store it indoors. If you prefer to keep it connected, use a quality battery tender to maintain charge. Either way, a well-cared-for battery ensures your motorcycle starts right up when the season turns.
Keep Tires in Shape During Winter Storage
Cold temperatures and long months of sitting can cause tires to lose shape or develop flat spots. A little preparation keeps them ready for the first ride of spring.
Use a stand: The best method is to lift the motorcycle completely with a center or paddock stand. This removes weight from the tires and prevents flat spots.
If no stand is available: Move the motorcycle every few weeks to change the contact point on the tires. This small step keeps pressure evenly distributed.
Protect from damage: Avoid leaving tires directly on cold concrete. Place carpet squares, rubber mats, or a sheet of plywood under each tire to block moisture and protect the rubber.
Check tire pressure before and after storage so the bike is ready to roll smoothly when the roads clear.
No Vacancy for Critters
When temperatures drop, small animals start shopping for winter real estate. Don’t let your motorcycle become the coziest cabin in the neighborhood.
Block entry points: Plug exhaust pipes and air intakes with cloth or steel wool to keep out your unwanted tenants.
Discourage visitors: Scatter a few mothballs nearby, but keep them off the paint. The smell alone will convince even the boldest mouse to find other lodging.
Skip the snacks: Avoid leaving food or wrappers near your storage spot. Rodents have great noses and zero respect for personal property.
A few simple precautions now can save you from discovering a mouse condo under your seat come spring.
Check Your Bike Midwinter
Even while your bike hibernates, it deserves a little attention. Once or twice during the winter, take a few minutes to ensure the cover is snug and dry. Watch for leaks or condensation, and roll the wheels slightly to keep them loose. Look for any signs of leaks or condensation, and roll the wheels slightly to keep them loose. A quick glance now prevents headaches when it’s time to ride again.
