Winter’s almost here, and you know what that means – time to put your motorcycle into storage. But where to put her? The garage is full and dad says no shelters in the yard.

Can I leave my motorcycle outside in the winter? Yes, storing outside is possible if done right. From what fluids to top off to critter-proofing, we’ve got you covered – no rusty surprises in the spring on our watch.


  • Proper fluid maintenance is critical for winter storage. Draining old oil and topping off fluids helps prevent moisture buildup that can cause corrosion over time.
  • Use a bike cover and locks/alarms to protect against weathering and theft. Covers shield from rain, snow, and sunlight while locks deter would-be thieves looking to “borrow” unattended bikes.
  • Small preparations can make a big difference in spring. Steps like changing oil, adding stabilizer, and inspecting components catch small issues before the riding season. Taking time now saves money and headaches later when it’s time to ride again.

Can I Leave My Motorcycle Outside in the Winter?

We often get this question from folks. The short answer is yeah, it’s possible…if done correctly. A lot of riders don’t have garages, so outdoor storage is the only choice. But it takes some work to make sure the bike is protected.

The key things are prepping the fluids, covering up, and maybe adding a small roof or shelter if you can. Draining the gas and stabilizing is smart too. Batteries don’t love freezing temps, so maybe bring those inside if you’re worried. As long as there’s no place for water to get in, she should fare just fine in the elements.

We’ve seen guys use simple DIY shelters like wooden frames with a tarp – stuff like that goes a long way compared to just a bike cover flapping around.

If those bases are covered with the right preventative measures, absolutely she can tough it out outside. It’s not ideal compared to an insulated garage, but doable with common sense storage practices. Just check on her a few times to ensure all’s well under the wraps.

How to Prepare the Motorcycle for Winter Storage

Properly storing a motorcycle involves safeguarding it against the harsh elements and potential issues that can arise during the cold months.

Let’s explore key steps and tips to protect your motorcycle during its winter hibernation and guarantee a trouble-free riding experience in the seasons to come.

1. Change the Oil

This first step is really important – we want to change that old, used-up motor oil before storing our bike for the winter. Leaving it in there can cause corrosion over time.

Let’s drain it out and refill with fresh oil. Don’t forget to also top up any other fluids like brake fluid or coolant too. Can’t leave those reservoirs half empty!

2. Top Off Other Fluids

Speaking of fluids, we’ll want to fill her up in any other areas that tend to collect moisture. That means topping off the gas tank too after adding some fuel stabilizer.

No sense giving those tiny droplets of water a place to sneak in and set up shop. Check radiator fluid, brake lines – anything holding liquid. Closed system, people! Cover all bases.

3. Store the Battery Properly

This gal isn’t gonna start herself come spring without some battery love. I like to just take mine inside the house for the winter where it’s warm and toasty.

But a battery tender works great too if you wanna keep it on the bike. Plugs right in to keep her cells happy until we’re riding again. Can’t be leaving her out in the cold!

4. Add Fuel Stabilizer

Wouldn’t want that gas we just put in turning funky on us before the season’s over. Stabilizer to the rescue – just follow instructions to dose it right then run the engine a bit so it circulates.

Our fuel system will thank us later when we don’t need to clean carb jets or change clogged filters.

5. Keeping Tires Tip Top

We want to make sure those tires last through the winter too. Over-inflating them a bit can help prevent flats spots from sitting. I like to use tire pumps rated for motorcycle tires – they get the job done right. Just don’t go too nuts with the PSI.

You can also elevate the wheels off the ground if possible. I’ve used those plastic milk crates before in a pinch. The center stand works great too. Anything to take the weight off while she’s hibernating.

6. Batteries and Beyond

As a last step, do one final check that everything’s topped off. Fluids, battery, you name it. Maybe even prep a maintenance checklist for next spring so nothing gets forgotten.

Now’s also a good time to inspect things carefully. Take a close look at wires, hoses, and any othercomponents that see wear and tear. Better to handle small issues now than be scrambling come rode season!

7. Security Solutions

Last but not least, security. You’ll want some kind of cover and maybe even a lock to keep unwanted visitors away over the long months. Covers come in all price ranges – just get one rated for your climate.

As for locks, there are disc/rim types that can’t be removed without the key. Alarms too. Peace of mind is worth it for times away. Never hurts to be extra cautious with valuables outdoors all winter!

Potential Motorbike Issues from Improper Storage

Improperly storing a motorbike during winter can lead to a myriad of issues, turning a dormant period into a maintenance nightmare. From fuel system problems and battery deterioration to tire damage and rust formation, neglecting essential storage steps can have lasting consequences.

Understanding the potential pitfalls of improper storage is crucial for maintaining a motorcycle’s longevity and optimal functionality.

a. Fluid Problems

If we don’t prep the fluids right before storing, y’all, they can get funky over winter. That little bit of water sneaking in can cause all kinds of gunk and corrosion.

Carb jets, fuel pumps, you name it – they’ll all be junk come spring. And the coolant will also go bad.

b. Gaskets and Seals

All those rubber gaskets and seals holding in our fluids can dry out and crack too if we don’t protect them. Then it’s leak city come ride season.

Not to mention leaving old oil in. Yuck! That stuff’s like acid over months. Eats away at everything.

c. Tires Take a Beating

These babies are just as susceptible to improper storage. Leaving them parked one spot all winter puts dents and flat spots in no time.

Trust me, I’ve seen sad saggy tires that never held air again! Not a pretty picture, or safe way to kick off the season.

d. Drivetrain Disaster

Probably the worst part to ignore is that drivetrain. All the metal bits left out naked in the weather just beg for rust.

Next thing you know, seized pistons and holes in the cases. Draining the bank account fast! Not to mention driveshafts and gears grinding away. Yeeowch, make it stop!

e. Moisture Mayhem

The main problem with improper storage is all the moisture that sneaks in when things aren’t sealed up tight. All it takes is a few little droplets to wreak havoc over months of freeze-thaw cycles. That water gets into everything!

Fluids get diluted and gunked up. Rubber starts cracking as it dries out. And metal? Forget about it. One patch of surface rust is all it takes before the whole thing is fused solid.

f. Shocks and Sags

Suspension components can take a hit too from sitting idle. All that weight compresses springs and wears bushings over time. Next thing you know, forks are spongy and shocks leak like sieves! Not a smooth ride by any means.

Tires, I mentioned, but saddles and seats collect grime too. Mice and mold love feasting on dirty foam left outdoors all winter. I might as well buy new at that point rather than deep clean.

g. Bugs, Birds, Bats…Oh My!

Speaking of hitchhiking critters, leaving any areas exposed is just asking for hobo guests. Air boxes, intake boots, you name it – they’ll shred it for nests.

And don’t even get me started on what squirrels do to wiring! Battery cables become chew toys real fast.

In the end, a little work now equals big savings later. Nothing ruins a ride like breakdowns from neglected storage. Best we do it right from the get go!

Additional Tips for Winter Motorcycle Outside Storage

Maximizing the effectiveness of winter motorcycle storage involves more than the basics. Outdoor storage presents unique challenges, demanding additional precautions to shield your bike from the elements.

Implementing these supplementary measures ensures added defense against snow, ice, and cold temperatures, maintaining your motorcycle’s condition throughout the winter freeze.

Start the Bike Periodically

I like to start her every few weeks if possible, just to circulate fresh oil and keep things loose. Let it get fully warmed up too – don’t shortchange the warm up time.

An idling engine ain’t the same as one at operating temp. It helps blow out moisture and keep tabs on any small issues before the season.

Consider Tire Stands or Center Stand

Speaking of heat, elevating those tires is crucial. Tire stands or the center stand do the trick. I even know guys that use old tire rims or wood blocks in a pinch!

Anything to prevent flat spots and cracking from the long term weight. Suspension and bearings will thank us.

Apply WD-40 or Similar Chemical

While we’re at it, cover up any exposed metal with a good coat of grease or corrosion-x. Brake calipers, suspension bits, you name it.

Frames usually last just fine naked, but covering can’t hurt. Same goes for batteries – wrap them snug before bringing inside.

WD-40 Original Formula

WD-40 Original Formula, Multi-Use Product with SMART STRAW SPRAYS 2 WAYS, 12 OZ [3-PACK]


  • Eliminates moisture-induced short circuits
  • Prevents rust and corrosion
  • Frees stuck parts
  • Removes grease and other sticky substances
  • Lubricates moving parts


Storing outdoors means critter prevention too. Stuff exhausts and intakes tight with a rag since rodents love making nests there.

I also like to throw a dryer sheet or two inside saddles and compartments – most animals can’t stand the smell. Small steps but can save you big headaches down the line!

Removal and Relocation

For extra protection, consider removing any removable parts and storing them inside over winter. Things like saddlebags, windscreens, mirrors – anything that could get cracked or brittle outside. Batteries too if you’re not on a tender.

I’ve also known folks to rent a small storage unit just for their bikes over the colder months. Might be an option if you’re really worried about hail or other damage.

Inspect and Inventory

While you’ve got everything apart, do a full inspection and stock up on any parts you may need come spring. Belts, brake pads, bulbs, etc.

It’s nice to have those little items on hand so you’re not rushing a repair once the roads are clear again.

And definitely do an inventory of all tools and manuals – I’ve misplaced more than one specialty wrench or wiring diagram over the years. Having the full set saves headaches later on.

Cover Choice

On the topic of covers, choose one rated for your climate. Heavy duty material if you get crazy weather. Look for tight seams and overlap so water/snow can’t sneak in. Secure it down so it doesn’t blow away too – don’t want your cover becoming a neighborhood sail!

Custom or fitted covers offer the best protection but there are plenty great universal options too. Just do your research to find the right one for your bike and location.

FAQs About Leaving Motorcycle Outside in the Winter

Can I leave my bike outside if it’s not running/needs repairs?

It’s riskier to store a non-running bike outside long-term. Moisture can more easily intrude and cause damage over winter. Try to repair or have a friend store it if possible. At minimum, fully drain fuel and regularly charge the battery.

How often should I start a bike while stored outside?

Most say every 4-6 weeks is a good interval to start the engine for 5-10 minutes. This circulates fresh oil to prevent corrosion. Be sure to let it fully warm up each time.

What’s the best type of cover for heavy rain/snow areas?

Breathable, heavy-duty bike covers designed for harsh weather work best in extreme climates. Look for sealed seams, overlap, and grommets for tie-downs. Custom fitted ones provide maximum protection.

How do I protect batteries on dual-sport bikes used for trails?

For off-road bikes left outside, a battery tender/maintainer plugged into the bike’s charging system works great. Some also remove AGM/gel batteries and store inside or in an insulated box.
