As the vibrant fall foliage begins to fade and temperatures start to drop across Western North Carolina, many powersports enthusiasts face the bittersweet reality of preparing their vehicles for the off-season. While it might be tempting to squeeze in those last few rides before hurriedly stashing your motorcycle, ATV, or UTV away, a proper winterization process requires thoughtful planning and execution.
Why Early Winterization Planning Makes All the Difference
At Waynesville Cycle Center, we’ve seen firsthand how early preparation can save riders thousands in repairs and ensure their machines start up perfectly when spring arrives. This comprehensive guide will walk you through everything you need to know about winterizing your powersports vehicle the right way.
Winterization Timeline: When to Begin the Process
The key to effective winterization isn’t rushing through a checklist the day before snow flies—it’s following a methodical timeline that protects your investment throughout the changing seasons.
Early Fall (September-October)
- Begin researching and purchasing needed winterization supplies
- Schedule professional maintenance checks while service departments aren’t backlogged
- Identify potential storage solutions if you don’t have adequate space
- Make a list of any repairs you’ve been postponing that should be addressed before storage
Mid-Fall (Late October-November)
- Perform thorough inspection of your vehicle
- Address any maintenance issues before they sit all winter
- Deep clean your vehicle while temperatures still permit outdoor washing
- Start reducing fuel levels if you plan to drain the tank
Late Fall (November-December)
- Complete final winterization procedures
- Position vehicle in its winter storage location
- Implement storage security measures
- Document winterization steps taken for reference in spring
Starting early allows you to spread the work over several weekends rather than trying to complete everything in one rushed session when temperatures have already dropped significantly.
The Ultimate Powersports Winterization Checklist
1. Fuel System Protection
Fuel system issues are among the most common and costly problems that arise from improper winterization. Modern ethanol-blended fuels begin to deteriorate in as little as 30 days, leading to varnish deposits and corrosion.
For Short-Term Storage (3-4 months):
- Fill the gas tank completely to prevent condensation
- Add high-quality fuel stabilizer (follow manufacturer’s recommendations for dosage)
- Run the engine for 10-15 minutes to ensure treated fuel circulates through the entire system
- Consider premium non-ethanol fuel for final fill-up
For Long-Term Storage (5+ months):
- Some manufacturers recommend draining fuel systems completely
- Consult your owner’s manual for specific recommendations
- If draining, run the engine until fuel lines are empty
- For carbureted machines, drain float bowls completely
2. Battery Maintenance
Battery failure is the #1 reason for “no-start” conditions after winter storage. Take these steps to keep yours healthy:
- Remove the battery if storing in unheated locations where temperatures will drop below freezing
- Clean battery terminals and connections with a mixture of baking soda and water
- Apply dielectric grease to terminals to prevent corrosion
- Connect to a quality battery maintainer/tender designed for powersports batteries
- Store removed batteries in a climate-controlled environment (50-70°F is ideal)
- Check electrolyte levels in conventional batteries and top off with distilled water if necessary
3. Fluid Protection
Engine oil contains acidic byproducts that can damage internal components during storage:
- Change the oil and filter before storage, not after
- Consider using manufacturer-recommended winter/storage-specific oil if available
- Check and top off all other fluids (brake, clutch, coolant)
- Ensure coolant has adequate antifreeze protection for your area’s lowest temperatures
- For hydraulic systems, work fluid through components to prevent seals from drying
4. Exterior and Component Protection
Proper exterior care prevents deterioration and keeps your vehicle looking its best:
- Wash thoroughly to remove all dirt, bugs, and road grime
- Apply appropriate protection products to painted surfaces
- Apply a light coat of WD-40 or appropriate protectant to exposed metal parts
- Spray light oil on control cables
- Apply leather/vinyl conditioner to seats
- Consider a breathable, vehicle-specific storage cover (avoid plastic tarps that trap moisture)
- Lubricate chain (for chain-drive motorcycles)
5. Tire and Suspension Care
Flat-spotting and tire degradation are common winter storage problems:
- Inflate tires to manufacturer specifications
- Ideally, suspend the vehicle to take weight off tires (motorcycle stands, ATV/UTV jack systems)
- If suspension isn’t possible, rotate tires every 4 weeks
- Place vehicles on concrete rather than bare earth or grass
- Consider placing a carpet remnant or rubber mat between tires and cold concrete

Specific Winterization Requirements by Vehicle Type
Motorcycles
- Remove spark plugs and add a small amount of oil to cylinders (for long-term storage)
- Plug exhaust pipes and air intakes to prevent moisture and critter intrusion
- Consider removing fairings for better air circulation in storage
- For shaft-drive motorcycles, check final drive oil
- Place on center stand if available to minimize tire contact
ATVs
- Remove or disconnect CVT belts on applicable models
- Clean and oil air filters
- Grease suspension components
- Apply dielectric grease to electrical connections
- Consider removing seats for long-term storage to prevent moisture accumulation
UTVs/Side-by-Sides
- Remove the windshield or roll up soft enclosures to prevent distortion
- Disconnect and remove accessories that could drain the battery
- Lubricate door hinges and latches
- Block off exhaust and intake with steel wool (prevents rodent nesting while allowing airflow)
- Apply corrosion protection to winch cables and components

Common Winterization Mistakes to Avoid
Years of helping riders revive their machines after winter storage has taught us what NOT to do:
- Never store with partially filled fuel tanks – This creates condensation space that leads to corrosion
- Don’t skip the fuel stabilizer – Even with a full tank, untreated fuel deteriorates
- Avoid covering a dirty vehicle – Dirt holds moisture against surfaces, causing corrosion
- Don’t store directly on earth floors – Moisture wicks up through concrete, but much more through dirt
- Never leave weight on suspension for months – This damages seals and can deform components
- Don’t forget to check on your vehicle – Monthly inspections catch problems early
- Avoid using household plastic tarps – These trap moisture and cause more harm than good
Planning for Spring Startup
A great winterization process includes planning for spring reactivation:
- Create a checklist for spring startup procedures
- Keep a record of what you did during winterization
- Store smaller components (removed parts) in labeled bags
- Set calendar reminders for battery maintenance if using a tender
- Keep keys and important documents in a designated place

Winterizing Your Powersports Vehicle FAQs
How cold is too cold to store my powersports vehicle in an unheated garage?
Modern powersports vehicles can handle cold temperatures if properly winterized. However, extreme cold below 20°F can cause plastic and rubber components to become brittle. The bigger concern is temperature fluctuation, which causes condensation. A consistently cold environment is better than one that swings between warm and freezing.
Do I really need to change oil before storage rather than after?
Yes. Used oil contains combustion byproducts and acids that will damage engine components during storage. Fresh oil provides better protection throughout the winter months. You don’t need to change it again in spring unless your vehicle sits for more than 6 months.
What’s the minimum I absolutely must do if I’m short on time?
At minimum: stabilize the fuel, protect the battery, and keep the vehicle covered and off the ground. However, this minimal approach significantly increases the risk of problems come springtime.
How do I prevent mice and other pests from nesting in my stored vehicle?
Steel wool in exhaust and intake openings (ensure it’s visible so you remember to remove it), mothballs around (not on) the vehicle, peppermint oil-soaked cotton balls, and regular checks are your best defenses. Ultrasonic repellers show mixed effectiveness.
Is it better to store indoors or use a quality cover outdoors?
Indoor storage is vastly superior. Even the best covers can’t protect against extreme temperature fluctuations, moisture, UV damage, and pests. If outdoor storage is your only option, consider a storage unit rental for the winter months.
