The ratchet for Honda Dio scooters is a part of the kick starter mechanism: when the lever is pressed, it engages and turns the crankshaft, and then disengages.
Replace it if the teeth are stripped: the lever slips and does not start the engine. Also check the mating part and the spring.
- While you are at it, inspect the neighboring parts of the assembly: they often wear out together.
Country of origin: China.
