Preparing your motorcycle for winter storage: the full checklist

Why winterisation matters

A motorcycle stored carelessly will greet you in spring with: dead battery, clogged carburettor, deformed tyres, rust marks. 2 hours of preparation in autumn beats a frustrating and expensive restart.

The winterisation checklist

1. Fuel

Modern fuel (with ethanol) degrades in a few months and clogs the system. Fill the tank (prevents condensation in an empty one) and add a stabiliser, then run the engine for 5 minutes so it reaches the carburettor/injectors. Details in our article on stabiliser before storage.

2. Battery

It's winter's #1 casualty. Disconnect it and connect a battery maintainer (Optimate/CTEK type), or store it somewhere warm and recharge every 1–2 months. See our guide on winter motorcycle battery maintenance.

3. Tyres

A stationary tyre in the same spot gets flat-spotted. Overinflate by 0.3–0.5 bar, and if possible put the bike on workshop stands to unload the tyres. Avoid direct contact with cold ground (cardboard/wood underneath).

4. Humidity and corrosion

The silent enemy. Dry, ventilated location, breathable cover (plastic sheeting traps condensation and promotes rust). A coat of protectant on bare metal parts helps.

Getting back on the road

In spring: reconnect the battery, check fluid levels, verify tyre pressure, and do a brake control check before riding.
