How to Prepare Your Vespa or Lambretta for Winter Storage

As the summer comes to an end and the days get shorter, many classic scooter owners start thinking about putting their Vespa or Lambretta away for the winter.

If your scooter is going to sit in a workshop or storage unit for four, five or six months, it's worth spending a little time preparing it properly.

Simply parking the scooter up, putting a cover over it and walking away until spring can lead to problems that could have easily been avoided.

Fuel can deteriorate, batteries can go flat, moisture can cause corrosion, tyres can lose pressure and, on Lambrettas in particular, the wrong type of cover can cause problems with aluminium parts.

In this guide, we'll look at the do's and don'ts of winter storage for classic Vespa and Lambretta scooters, including what to do with the fuel, battery, tyres, engine, bodywork and covers.

Why Prepare Your Scooter for Winter?

A classic scooter may be perfectly happy sitting unused for several months, but it needs to be stored correctly.

During a four-to-six-month storage period, your scooter can be exposed to:

• Condensation
• Damp air
• Temperature changes
• Fuel deterioration
• Battery discharge
• Corrosion
• Flat spots or pressure loss in tyres
• Moisture trapped underneath covers
• Deterioration of rubber components

The good news is that most of these problems are easy to prevent.

A little preparation now can save a lot of work when you're ready to ride again.

1. Choose the Right Place to Store Your Scooter

A dry workshop or storage unit is ideal.

If possible, avoid storing your scooter somewhere that is:

• Permanently damp
• Poorly ventilated
• Subject to large temperature fluctuations
• Prone to condensation
• Exposed to water leaks

A dry garage or workshop is much better than leaving a scooter outside under a cover.

But remember...

A workshop can still become damp.

Cold weather followed by warmer temperatures can create condensation on metal surfaces, so don't assume that because the scooter is indoors it is automatically protected from moisture.

2. Give the Scooter a Proper Clean

Before storage, give the scooter a thorough clean.

Remove:

• Dirt
• Road salt
• Mud
• Oil
• Grease
• Insects
• General road grime

This is particularly important if you've been riding the scooter during wet or salty conditions.

Road dirt and salt left on the scooter for several months can encourage corrosion.

Once clean, dry the scooter thoroughly.

Pay particular attention to:

• Under the floorboards
• Inside the legshield area
• Around the engine
• Around the hubs
• Around the rear brake
• Around the mudguards
• Around fasteners and brackets

Don't put a wet scooter straight into storage and cover it up.

3. What Should You Do With the Petrol?

This is one of the biggest questions we get asked about winter storage.

Should you leave the tank full?

Should you drain it?

Should you use E5?

Should you use a fuel stabiliser?

There isn't one answer that applies to every scooter, but fuel quality is particularly important with a classic scooter that is going to sit unused for several months.

4. Be Careful With Ethanol Fuel

Modern UK petrol can contain ethanol.

E10 petrol contains up to 10% ethanol, while E5 contains no more than 5% ethanol. E10 became the standard 95-octane petrol grade in Great Britain in 2021, while E5 remains available in the higher-octane "super" grades.

This is particularly relevant to classic scooters.

The UK Government specifically notes that classic, cherished and older vehicles may not be compatible with E10, and recommends E5 where compatibility is uncertain.

Ethanol can also contribute to corrosion and can cause compatibility problems with some older fuel-system materials. The AA notes that, during long-term storage, ethanol-containing fuel can contribute to corrosion of certain metals and can affect some seals, gaskets and rubber materials.

For a classic Vespa or Lambretta being stored for four to six months, this is something worth taking seriously.

5. E5 Is Our Preferred Choice for Long-Term Classic Scooter Storage

If you're storing a classic Vespa or Lambretta for the winter and you have the choice, E5 petrol is generally the sensible option for an older fuel system, particularly if you don't have confirmed E10 compatibility.

However, fuel compatibility should always be considered alongside the condition and specification of your particular scooter.

If you're unsure, use E5 and check the manufacturer's guidance.

The UK Government specifically advises owners of vehicles not listed as E10-compatible to continue using E5 petrol.

6. Don't Leave Old Petrol Sitting in the Carburettor

The petrol tank isn't the only part of the fuel system you need to think about.

The carburettor can contain fuel that sits there for months.

On a classic scooter, this can result in problems when you come to start it again.

Depending on the scooter and how you're storing it, consider:

• Turning off the fuel tap
• Allowing the engine to run the carburettor dry
• Draining the carburettor bowl where appropriate
• Following the instructions for any fuel stabiliser you use

If you're unsure about the correct procedure for your particular carburettor, follow the carburettor manufacturer's recommendations.

7. Should You Use Fuel Stabiliser?

A suitable fuel stabiliser can be useful when petrol is going to be stored for an extended period.

If you choose to use one:

1. Use a product designed for petrol.
2. Follow the manufacturer's dosage instructions.
3. Add it to fresh fuel.
4. Run the engine sufficiently to circulate the treated fuel through the system, where the product instructions call for this.

Don't simply pour an unknown additive into the tank and assume it will solve every fuel-storage problem.

8. Don't Leave the Tank Nearly Empty

A tank containing a large amount of empty space can be more susceptible to condensation.

Moisture inside a steel fuel tank isn't something you want sitting there for several months.

If you are following a full-tank storage approach, use fresh, appropriate fuel rather than leaving an old tank of fuel sitting there for months.

For older scooters, however, the most important point is to make sure the fuel you use is appropriate for the scooter and that you have considered the effects of long-term storage.

9. Consider the Condition of the Fuel Tank

Before putting the scooter away, have a look inside the fuel tank if possible.

Check for:

• Rust
• Contamination
• Water
• Dirt
• Old fuel residue

A scooter that already has a rusty tank isn't going to improve simply because it's been parked up for winter.

If the tank needs attention, winter can actually be a good time to deal with it.

10. Check the Engine Oil Where Applicable

On scooters with a separate gearbox oil system, check the oil level and condition before storage.

This is particularly relevant to Lambrettas and manual Vespa models.

If the oil is due for replacement, doing it before storage can be preferable to leaving old contaminated oil sitting in the engine.

Look for:

• Correct oil level
• Leaks
• Metal particles
• Unusual contamination

If you find anything unusual, investigate it before putting the scooter away.

11. Protect the Engine

For a normal four-to-six-month winter storage period, there's generally no need to overcomplicate engine preparation.

However, make sure the engine is left in good condition.

Before storage:

• Check for oil leaks
• Check the spark plug
• Check the air filter
• Make sure the engine is clean
• Make sure the fuel system is dealt with correctly

If the scooter has been running poorly, don't use winter storage as an excuse to ignore it.

Fix the problem now.

12. Remove or Look After the Battery

If your Vespa or Lambretta has a battery, don't simply leave it connected for six months and hope for the best.

A battery can gradually discharge while the scooter is sitting.

A deeply discharged battery can suffer permanent damage.

For long-term storage, consider:

• Disconnecting the battery
• Removing the battery
• Keeping it somewhere suitable
• Using an appropriate battery maintainer

If you use a battery charger or maintainer, make sure it is suitable for the type of battery you have and follow the manufacturer's instructions.

13. Check the Tyres

Before storage, check both tyres.

Look for:

• Correct pressure
• Cracks
• Perishing
• Damage
• Uneven wear
• Objects embedded in the tread

Inflate the tyres to the appropriate storage pressure recommended for your scooter and tyres.

Don't forget to check them again before riding in spring.

14. Don't Ignore the Tyres Just Because the Scooter Isn't Moving

A scooter sitting in one position for several months isn't ideal for the tyres.

Where practical, moving the scooter slightly during a long storage period can change the contact patch.

If the scooter is being stored for an extended period, a suitable stand or support arrangement can also reduce prolonged loading on one section of the tyre.

However, make sure the scooter is stable and safely supported.

15. Lubricate Where Necessary

Winter storage is a good opportunity to inspect and lubricate the appropriate moving parts.

Depending on the scooter, this can include:

• Cable ends
• Control mechanisms
• Levers
• Pivot points
• Stand mechanism
• Other exposed moving components

Don't spray lubricant everywhere.

Use the correct lubricant for the particular component.

16. Protect Chrome and Painted Surfaces

Before storage, make sure the bodywork is clean and dry.

A suitable protective wax or corrosion-protection product can help protect painted and metal surfaces.

Pay particular attention to:

• Chrome
• Fasteners
• Bare metal
• Exhaust
• Floor rails
• Hub components

The aim is to prevent moisture sitting directly against vulnerable surfaces.

17. Lambretta Owners – Be Careful With Your Cover

This is particularly important if you own a classic Lambretta.

A lot of people assume that a breathable cover is automatically the best option.

That's not necessarily the case.

If the scooter is stored in a damp environment, moisture can still become trapped around parts of the scooter.

On Lambrettas, this can be particularly problematic around aluminium components such as the handlebars and horncast.

Moisture held against aluminium for extended periods can lead to staining, oxidation and corrosion.

This can be especially frustrating on a beautifully restored Lambretta where the aluminium has been polished.

18. Don't Put a Damp Cover Over Your Lambretta

One of the worst things you can do is cover a damp scooter and then leave it for months.

If the scooter or cover is wet, allow everything to dry properly first.

A cover should protect the scooter from dust and accidental contact while not creating a damp microclimate around the bodywork.

19. Breathable Doesn't Mean "Leave It Touching the Scooter"

A breathable cover can be useful, but consider how the cover sits on the scooter.

If the material is constantly touching polished aluminium and moisture is present, you can still end up with problems.

On a Lambretta, take particular care around:

• Handlebars
• Horncast
• Legshield
• Side panels
• Polished aluminium components

If you're storing a valuable or freshly restored Lambretta, it's worth thinking about how the cover interacts with the actual scooter, rather than simply buying the first breathable cover you find.

20. Give Your Lambretta Some Air

Where possible, store the scooter somewhere dry with reasonable ventilation.

Don't seal the entire scooter in an airtight environment while moisture is still present.

A dry storage environment is much more important than simply wrapping the scooter in layers of covers.

If your storage unit is prone to condensation, consider ways of reducing humidity and improving ventilation.

21. Keep Covers Away From Hot Exhausts

This sounds obvious, but make sure the scooter is completely cool before covering it.

Never put a cover over a hot exhaust.

Allow the scooter to cool completely before covering it.

22. Don't Forget the Brakes

Before storage, inspect the brakes.

Check:

• Brake operation
• Brake cables
• Brake fluid where applicable
• Brake shoes/pads
• Leaks
• General condition

If the scooter has a brake problem, fix it before storage rather than waiting until spring.

23. Check for Oil and Fuel Leaks

Before leaving the scooter, look underneath it.

Check for:

• Petrol
• Gearbox oil
• Brake fluid
• Other fluids

A small leak can become a much bigger problem if the scooter is left unattended for several months.

24. Give the Scooter a Final Inspection

Before you lock the workshop or storage unit, walk around the scooter.

Check:

☐ Fuel system prepared
☐ Fuel tap off
☐ Carburettor dealt with
☐ Battery disconnected/maintained
☐ Tyres checked
☐ Engine oil checked
☐ Brakes checked
☐ Scooter cleaned
☐ Bodywork dry
☐ Metalwork protected
☐ No leaks
☐ Cover fitted correctly
☐ Storage area dry

What NOT to Do When Storing Your Vespa or Lambretta

Don't leave old E10 fuel sitting in the scooter indefinitely

For older scooters, consider E5 and follow appropriate fuel-storage procedures. UK Government guidance specifically highlights classic and older vehicles as a group that may not be compatible with E10.

Don't leave the battery completely flat

Either disconnect it appropriately or use a suitable battery maintainer.

Don't cover a wet scooter

Dry it first.

Don't use a dirty cover

Dirt trapped against paintwork can cause scratching and hold moisture against the scooter.

Don't ignore corrosion

Deal with corrosion before storage where possible.

Don't forget the carburettor

Old fuel sitting in the carburettor can create problems when you try to restart the scooter.

Don't assume "breathable" means completely safe for aluminium

On Lambrettas, pay particular attention to polished aluminium handlebars and the horncast.

Don't leave the scooter with a known fault

Winter is a good opportunity to repair problems before the riding season begins.

Final Thoughts

Putting your Vespa or Lambretta away for winter doesn't need to be complicated.

The key is to prepare the scooter rather than simply park it.

Use suitable fuel, take care of the battery, check the tyres, clean and protect the bodywork, deal with any existing faults and make sure the storage environment is as dry as possible.

And if you're storing a Lambretta, remember that the wrong cover or a damp storage environment can cause problems with aluminium parts such as the handlebars and horncast.

Four to six months is a long time for a classic scooter to sit unattended.

Spend an hour preparing it properly in the autumn and you could save yourself considerably more time and money when spring arrives.

At Scooter Vista, we stock a wide range of Vespa and Lambretta parts, service items, tyres, electrical components, fuel-system parts and restoration products to help keep your classic scooter in top condition all year round.

Look after it through the winter, and it'll be ready for the road when the sun comes back.
