Preparing Your Motorcycle for Winter Storage


With summer winding down and autumn up to bat, it’s time to think about whether you want to store your motorcycle or not.

Fluid Check

All engine fluid, including brake, clutch, and coolant, should be checked. You may even consider draining them completely and refilling. Antifreeze can help to prevent engine freezing. Also, remember to lubricate the throttle, kickstand, shifter, and clutch cables. Finally, fill your gas tank and add fuel stabilizer to avoid damage from old gasoline. Don’t forget to ride around the block once or twice so the fuel stabilizer has a chance to work through the carburetor.

Battery Conservation

Batteries don’t do well in cold weather, losing their charge even faster than normal. Make sure yours is prepared for the long winter. If you want to leave it on your bike, you’ll have to set up a trickle charger to keep it alive, or otherwise be in a position to start and run the bike regularly (which defeats the purpose of winter storage!). You can also remove it from your bike and hook it up to a trickle charge or battery maintainer. Just make sure it’s stored at room temperature and away from conductive surfaces.


Fluctuating or extreme temperatures and excessive sitting can wear on your bike’s tires. Prevent uneven wear by suspending your bike so the tires are off the ground and not taking the full weight of your motorcycle. If you can’t do that, fill your tires to the maximum recommended volume and rotate the front tire once a week to prevent flat spots. Setting your bike on blocks can achieve the same effect.

Check Engine Oil and Filter

Perform the basics of engine oil maintenance before putting your bike away for the winter. Likely this will mean changing out the oil and filter completely.  If you’re unsure, check the oil using your usual methods. Old oil can corrode engine parts if left unattended. Even if it’s in a questionable state, change the oil and filter just to be safe. 

Fog the Engine

Fogging your engine can prevent corrosion by coating the internal workings of your engine with a light oil. Just make sure you’re in a ventilated area, that any spark plugs that need replacing are dealt with before you start, and that you remove the air filter. Start your bike and spray the fogging oil as you increase the idle speed to 2,000 rpm. Stop spraying when the engine stops.


Mice and other vermin like to burrow in small dark places during cold months, and your mufflers and air cleaners are ideal homes for them. Block their entryway by stuffing a sandwich bag with steel wool and pushing it into the air intake and tailpipes. The bag keeps strands of steel wool out of the engine, just don’t forget to remove it in the spring!

Not every rider is blessed with winter weather suitable for motorcycle riding. While storing your bike might be like putting a good friend away for a few months, you’ll both be happy with the results of some proper maintenance and storage.
