Vertu Motorcycles' Guide To Winter Maintenance
For many motorcycle owners, the colder months mean it's time to tuck the bike away for a well-earned rest. For others, it's the season to stay on top of maintenance and brave the roads with extra care.
Whatever your approach, motorcycle maintenance over winter is crucial. Keeping your bike in top condition maximises performance and minimises the risk of problems when the riding season returns.
When the temperature drops and the roads turn unpredictable, here are several key things you should do to keep your motorcycle safe, healthy, and ready for action.
Change The Oil
Dirty or old oil can lead to corrosion and premature engine wear. Even if your bike won't see much use, winter is an ideal time to refresh your oil and filter.
Start the engine and let it run for a few minutes to reach operating temperature.
Drain the old oil, replace the filter, and refill with the viscosity recommended in your motorcycle's owner's manual.
Top Tip: If your manual allows, consider a winter-friendly multigrade oil to help with cold starts and better flow at low temperatures.
Treat and Protect the Fuel System
Modern petrol often contains ethanol, which can absorb moisture and deteriorate if left sitting.
If your bike will be parked for several weeks or more, fill the tank and add a fuel stabiliser before your final ride to mix it through the system. This prevents varnish build-up and corrosion inside the fuel lines.
Regularly Clean/Lube The Chain
Regular chain care makes a big difference to your bike's lifespan and performance.
Clean and lubricate your chain frequently. Ideally every week if you ride often, or after every wet or salty journey.
A paddock stand helps by allowing the rear wheel to rotate freely. Always clean the chain first to remove grit before applying fresh lube.
Top Tip: Lubricate your chain after a ride, not before as warm metal helps the oil penetrate and stay put, rather than being flung off as you ride.
Keep Your Battery in Good Health
Cold weather slows the chemical reactions in your battery, reducing its capacity. If you don't ride regularly, it can drain quickly.
If your garage has power, use a smart trickle charger to maintain the battery. If not, consider removing it entirely and storing it indoors in a cool, dry place.
Also, make sure the terminals are tight and coated with a little grease to keep out winter moisture.
Check and Refresh Your Coolant
If your motorcycle is liquid-cooled, check that your coolant mix is ready for sub-zero conditions. The antifreeze should protect down to at least −20 degrees, depending on your local climate.
If the coolant is old or discoloured, it's worth flushing the system and refilling with the correct mixture. If you're unsure, contact us, we'll be happy to help.
Grease Key Joints and Components
Grease helps protect moving parts, pivot points, and exposed threads from corrosion and wear.
Focus on stands, levers, footpegs, linkage pivots, and cable ends. Apply a light coating and recheck through the season. Avoid over-greasing and keep it away from brake components.
Regularly Wash and Protect Your Bike
Love it or hate it, washing your bike regularly through winter is essential. Road salt and grime can cause corrosion quickly.
After every ride, rinse your bike thoroughly with cold water. Hot water can dissolve salt crystals and drive them deeper into the metal. Also avoid high-pressure jets around bearings or seals.
Once dry, apply a corrosion inhibitor (like ACF-50 or XCP) to exposed metal parts and a protective wax to painted areas.
Top Tip: Pay special attention to the underside of your bike as it takes the brunt of winter grit and debris.
Check Your Tyres
Inspect your tyres before winter riding. If the tread depth is getting low, consider changing them. Good tread is vital for gripping wet or slushy roads.
Cold temperatures reduce tyre pressure, so check and adjust before every ride.
Top Tip: Don't believe the myth that under-inflated tyres improve grip - they don't, and riding on them can be dangerous.
If your bike will be stored for long periods, place it on paddock stands to prevent flat spots, or rotate the wheels occasionally. Regular winter riders may benefit from dual-compound or cold-weather tyres for better traction.
Adjust Your Suspension (If Possible)
Firm suspension settings reduce grip on slippery surfaces. Softening the suspension slightly, within manufacturer limits, can improve comfort and traction in poor conditions.
Reducing preload or damping helps the tyres maintain better contact with uneven, cold roads. Consult your owner's manual before making changes.
Look After Your Brakes
Brakes are especially vulnerable to road salt and moisture. Wash calipers regularly and check pads, discs, and lines for corrosion or sticking.
Also, check your brake fluid. If it's more than two years old or looks dark, have it replaced. Brake fluid absorbs moisture over time, reducing performance and causing internal corrosion.
General Storage Tips
If you're storing your bike for winter:
- Use a breathable motorcycle cover to protect against dust and condensation.
- Store in a dry, ventilated place or use desiccant packs if moisture is an issue.
- Start the bike briefly every few weeks to circulate fluids and keep seals lubricated.
- Use dielectric grease on exposed electrical connectors to prevent corrosion.
- And, of course, check your lights and indicators as visibility is critical during darker winter months.
