Bike cover: breathable fabric, not plastic sheeting

Dense polyethylene traps condensation underneath, and within weeks you get a film on the metal and moisture in the connectors. A cover should keep off dust and scratches while letting vapour out.

• Choose a breathable fabric cover, not plastic sheeting or tarpaulin without ventilation.
• Check for vent panels at the top and bottom, plus openings for a lock and straps.
• Pick the size by length and height including luggage and crash bars: a tight cover rubs on plastic and paint.
• Wash the bike and dry it completely before covering, and let the engine and exhaust cool down.
• Drape the cover so there is an air gap at the bottom, and secure it with a strap against gusts.
• Every few weeks take it off, check for damp and stains, and let the bike air out.
