It is not recommended to use a motorcycle after it has been submerged in water. Engine Damage: If the engine has been flooded, forcibly starting the motorcycle can cause severe deformation of the connecting rod. Additionally, insurance companies often refuse claims in such cases. Transmission Failure: If the water level rises above the engine compartment, the transmission is highly likely to be flooded. Once water enters the transmission, the vehicle may experience issues such as slipping, shaking, and rough gear shifting. This can also affect the transmission's lifespan and may even render it unusable. Interior Mold: The interior components are mostly made of absorbent materials. Rainwater contains numerous impurities and bacteria, and the enclosed, poorly ventilated space inside the motorcycle leads to extremely high humidity after submersion. This environment is conducive to mold growth.

My motorcycle was also flooded once when it was parked on the roadside and rainwater submerged the wheels. I quickly towed it to the repair shop. The mechanic said the engine might have taken in water and must not be started, otherwise it could cause engine damage. Wires in contact with water can easily short-circuit and burn out bulbs and the ignition system, so it's essential to thoroughly dry and inspect the wiring and fuses first. If the air filter gets wet, it needs to be replaced, otherwise dirt entering could cause more damage. The engine oil also needs to be checked for water contamination and cloudiness; if it's cloudy, it must be completely replaced. Overall, the chances of it being usable after flooding aren't high, but with proper handling, some losses might be mitigated. That time, I spent a few thousand to fix it and it could still ride, but it always felt like the power wasn't as smooth as before.

As a motorcycle enthusiast who frequently interacts with bikes, I believe whether a motorcycle can be used after being submerged depends on the specific situation. If the water only reaches the bottom of the wheels, it might not be a big issue—just drain the water and clean the electrical circuits. However, if the water rises to the height of the exhaust pipe or higher, there's a significant risk of water entering the engine, so never attempt to start it hastily! Disconnect the battery immediately, remove it, and check if the air filter is clogged. Electrical connectors are most prone to corrosion and rust, which can cause short circuits, so use a hairdryer to dry them slowly. Additionally, after submersion, the tires and braking system require a thorough inspection to avoid safety hazards. Remember not to ride in flooded areas, as these minor issues can accumulate and lead to premature scrapping of the bike.

Whether a motorcycle can be used after being submerged in water depends on the depth of flooding and duration. Water only reaching the wheel hubs may have minimal impact, but exceeding the exhaust pipe level could damage engine piston rings or cylinders. Electronic components like ignition coils and charging systems are prone to blown fuses or complete failure once flooded. I recommend immediately towing it to a repair shop to drain water from the chassis, air-drying for two days, then using a multimeter to detect short circuits and replace damaged parts. If submerged above the seat height, the circuit boards are likely irreparable. For safety, avoid rushing to ride; first conduct a test run to check brake performance and light functionality to prevent mid-ride malfunctions and accidents.
