My two wheeler's front suspension seems to be disloyal it does not absorb the pot holes it is supposed to instead it pass it on to my hands which ends up vibrating my entire body.What is the diagnosis process of it.How can I go ahead with repairing this, are there any parts which I can repair/replace like bearing ,bush or oil.etc.My Scooter is Honda Activa and is around 2 years old and clocked around 7000 kms.
Three things :
1) check tyre pressures,
2) check the shock absorber - replace if necessary,
3) avoid potholes - especially the larger ones as they can cause damage or, more seriously, an accident.
My guess would be breakdown in the damping mechanism of the suspension system. Without the effect of the damper you are experiencing only the spring. Depending on the suspension type the damper may need to be replaced or re-gassed or the oil refreshed and set to the correct level. To confirm the condition of the damper you can compress the suspension with the bike stationary and observe the speed at which the bike rebounds - if the bike rebounds very quickly then the damping is not functioning.
