Front hydraulic shock absorbers for Honda Dio scooters with a drum brake (as per the name). They form the front fork and absorb impacts from bumps.
Replace them if oil is leaking, the fork sags, it knocks under braking, or it works unevenly. Both shock absorbers are replaced, and the brake type must match your vehicle.
After replacing them, check the assembly at idle and while riding: there should be no unusual noises, leaks, or play.
