How to Winterise Your Motorcycle in South Africa
South Africa has a much longer riding season than most other countries, and we aren't subject to heavy snow and sub-zero temperatures..... most of the time. For those who choose to hang up their helmets during the colder times of the year, here's how you can protect your bike during the icy months.
Here in sunny South Africa, we are blessed with some of the finest riding conditions in the world. However, when winter rolls around, the climate takes a sharp turn depending on where you call home. While riders in the northern parts of the country face crisp, sub-zero Highveld mornings, bikers down in the Western Cape have to contend with months of relentless cold rains and damp coastal air.
Whether you plan to park your machine until spring or simply reduce your weekend runs, letting your bike sit idle without proper preparation is a recipe for expensive repairs. Before you hang up your helmet for the chilly months, follow this step-by-step guide to winterising your motorcycle the right way.
What is a pinlock?
1. Stabilise the fuel system
Leaving a half-empty fuel tank over winter invites condensation, which leads to rust inside the tank and water in your fuel lines.
- Top Up the Tank: Fill your tank to roughly 90% capacity. Leaving a small air gap allows for expansion while preventing moist air from settling on bare metal walls.
- Add Fuel Stabiliser: Pour in a quality motorcycle fuel stabiliser. Run the engine for 5–10 minutes so treated fuel circulates through the carburettors or fuel injectors. This stops petrol from breaking down and clogging your fuel system.
2. Change the oil and filter
Old engine oil contains acidic combustion by-products, dirt, and moisture accumulated over summer rides. If left sitting inside your engine for months, these contaminants can corrode internal components, bearings, and cylinder walls.
Drain the old oil while the engine is warm, replace the oil filter, and refill with fresh manufacturer-recommended oil. Fresh oil creates a protective layer over critical moving parts throughout the winter rest period.
3. Keep the battery alive
Cold temperatures are the ultimate killer of motorcycle batteries. A battery left connected to an idle bike will slowly discharge, leading to sulfation and a dead unit by the time spring arrives.
| Battery care strategy | Recommended method |
| Active Maintenance | Connect a smart battery tender/trickle charger directly to the terminals. |
| Long-Term Storage | Remove the battery, store it in a dry, room-temperature location, and charge monthly. |
4. Deep clean and corrosion-proof
Never put a dirty motorcycle into storage. Road grime, bug splatters, and coastal salt trap moisture against metal and paintwork, accelerating rust and pitting.
- Wash & dry: Thoroughly wash the bike with a dedicated motorcycle shampoo and ensure it is completely dry.
- Wax painted surfaces: Apply a layer of quality wax to painted bodywork and polished chrome to seal out humidity.
- Lube the drivetrain: Warm up the chain and apply a fresh coat of chain lube or corrosion wax.
- Protect exposed metals: Spray exposed metal fasteners, exhaust headers, and suspension linkages with a light coat of anti-corrosion spray or penetrating oil.
5. Elevate and protect your tyres
Leaving a heavy motorcycle resting on the same patch of rubber for months causes pressure loss and flat spots on your tyres.
- Use paddock stands: Ideally, place the bike on centre stands or front/rear paddock stands to lift both wheels clear of the cold garage floor.
- Alternative storage: If stands aren't available, inflate the tyres to their maximum recommended PSI. Place rubber mats or thick cardboard under the tyres to insulate them from cold concrete, and roll the bike a few inches every two weeks to shift the contact patch.
6. Cover it up properly
Finally, plug your exhaust tailpipe with a rubber wash plug or clean rag to keep out moisture and nesting insects. Cover the motorcycle with a dedicated, breathable bike cover. Avoid cheap plastic tarps, which trap moisture underneath and create a humid microclimate that breeds rust.
Taking an hour or two to properly prepare your machine ensures that when the warm South African sunshine returns, all you need to do is unplug the exhaust, check your tyre pressures, and hit the open road.
