CLEANING, CARE 19 – Treat bare metal (except for brake discs and the exhaust sys- tem) with a corrosion inhibitor. Preserving materials for paints, metal and rubber p. 164) – Treat all plastic parts and powder-coated parts with a mild cleaning and care product.
– Store the vehicle in a dry location that is not subject to large fluctuations in temperature. Info KTM recommends jacking up the motorcycle. – Raise the motorcycle with a lift stand. ( p. 66) – Cover the vehicle with a tarp or similar cover that is permeable...
STORAGE 20 Info Do not use non-porous materials since they prevent humidity from escaping, thus causing corrosion. Avoid running the engine for a short time only. Because the engine will not warm up sufficiently, the water vapor produced during combustion will condense, caus- ing engine parts and the exhaust system to rust.
