What to do if your engine seizes
 

Engine seizure means that the engine locks or freezes. It has the same result as a locked rear wheel. However, there is usually some advance warning of engine seizure, giving you time to respond.

Overheating or a lack of lubrication causes engine seizure. Without oil, the engine’s moving parts will no longer move smoothly against each other, and the engine will overheat. The first symptom may be a loss of engine power. You may also notice a change in the engine’s sound.

Pull off the road to the shoulder and stop. Let the engine cool. While you may be able to add oil and restart the engine, it should be thoroughly checked for damage.

If your motorcycle has a clutch and gears and the engine starts to seize, squeeze the clutch lever, disengaging the engine from the rear wheel, then pull off the road to stop.
