For most motorcycles, a 5×10 storage unit (50 sq ft) is the right size — big enough for the bike plus minor gear, small enough to keep cost down. Larger touring bikes, trikes, and bikes with sidecars usually need a 5×15 or 10×10. Climate-controlled storage extends bike life significantly, especially over winters or for long-term storage.

Sizing by motorcycle type

Climate-controlled vs. standard

For motorcycle storage, climate control matters more than for most household items. Reasons:

• Wood, leather, and plastic components (seat, grips, tank covering on some bikes) degrade in temperature/humidity extremes
• Battery life is shortened in extreme cold or hot environments
• Fuel system is more stable at consistent temperature
• Rubber components (tires, hoses, gaskets) age faster in heat

For summer storage (3-6 months), standard storage is usually fine.

For winter storage (5-6 months, especially in northern climates), climate-controlled is worth the 20-30% premium.

For long-term storage (1+ years), climate-controlled is strongly recommended.

Prep checklist before storing

1. Fuel system

• Fill the tank with fresh gas (full tank prevents condensation)
• Add fuel stabilizer per product instructions (essential for storage > 60 days)
• Run engine 5-10 minutes after adding stabilizer to circulate through fuel system

2. Battery

• Disconnect battery for storage > 60 days; OR
• Use a battery tender (smart trickle charger that maintains charge) — requires a powered unit or extension cord access
• Solar-powered tenders work even in non-powered units

3. Oil and fluids

• Change oil before long-term storage (used oil contains acids that corrode internals)
• Top off coolant
• Check tire pressure (proper inflation prevents flat-spotting)

4. Cover and protection

• Use a breathable motorcycle cover (not plastic — plastic traps moisture, causes rust and mildew)
• Place a sheet on the floor under the bike to absorb any condensation
• Consider tire cradles or putting bike on the centerstand to take weight off tires (long-term storage)

5. Documentation

• Keep registration and insurance current during storage
• Many facilities require proof of insurance for stored vehicles

What NOT to do

❌ Store with empty fuel tank (causes internal rust and condensation) ❌ Store with old oil (acids corrode engine internals over months) ❌ Use plastic cover (traps moisture) ❌ Leave keys in the bike ❌ Skip the battery — even sub-freezing temps drain modern batteries in weeks ❌ Forget to start it occasionally (if accessible — once a month minimum is ideal)

Insurance considerations

Most motorcycle insurance policies offer “laid-up” coverage during storage:

• Reduced premium for the storage period
• Maintains comprehensive coverage (theft, fire, vandalism)
• Drops collision/liability (since bike isn’t on the road)

Call your insurer before storage to set this up. Saves 30-50% of premium for the storage period.

Storage facility insurance does NOT cover your motorcycle (per Are Storage Units Insured?). Maintain your own coverage.

Snowbird motorcycle storage

If you’re storing a bike in your northern home while spending winter in FL/AZ:

• Set up storage in October-November
• Use fuel stabilizer + disconnected battery (or battery tender)
• Verify storage operator allows remote management for the season
• Return in April-May, top off battery, fresh fuel, brief inspection ride

Forward Storage’s Michigan, New York, and Pennsylvania locations are common snowbird bike-storage destinations.

Frequently asked follow-ups

How much does motorcycle storage cost? A 5×10 unit typically rents $60-95/month standard, $75-115/month climate-controlled. Significantly less than a dedicated motorcycle storage facility, which can charge $100-200/month.

Can I store a motorcycle outdoors? At Forward Storage, dedicated outdoor vehicle storage spaces are sometimes available — typically less expensive but with no weather protection. For long-term motorcycle storage, indoor units are strongly recommended.

What about a trailer for the motorcycle? A 10×20 unit fits most enclosed motorcycle trailers (bike inside the trailer). For just the trailer + bike combo, a 10×15 may work depending on trailer dimensions.

Can I work on my bike inside the storage unit? Light maintenance (checking battery, fluids, tire pressure) is fine. Major work (oil changes, fuel system work) is generally prohibited due to fire hazard and fluid disposal concerns. Use a home garage or dedicated workshop for repairs.
