[Resolved] Honda - Unicorn — low quality material and rusting problem
I am mechanical engineer, i bought unicorn from j.s.p honda on august 27 2007 just done 9000km.
i have the following problems, photos have been attached.
Most of the parts are getting rusted very easily. No steps for replacing it during service.
Spares available are not up to the standards (genuine Honda spare)
Spares are getting rusted inside the packing itself.
Chain guard is getting rusted
Rear stay (swing arm) is rusting
Chain has no proper tension evenly, lose at some point and tight at other points, sprockets are getting rusted. Don’t even live near coastal area.
Bike that I am using has done just 9000km and I am facing such terrible problems. Except the engine everything is dam waste, even the coating on the engine bore is pealing off. God dam bike.
Pivot sleeve and bearing
The metal used is worst quality, the metal sleeve should have higher hardness value than the present value Honda engineers have designed but its not so, the pin bearing 20*26*20 is easily producing impressions on the sleeve totally damaging the outer surface and restricting the rotary movement. and this happens as the pivot sleeve starts oxidizing.
The bearing that is on the chain side is exposed to loads from all the axis when compared with the other pin bearing on the other parallel side. Thus two bearings on each side swing arm has to be installed with a properly hardened pivot sleeve bush, or else instead of bearing its better to install hollow bush with vulcanized rubber coating.
Even the axle shafts are getting rusted. Wheel bearings are getting rusted, the plating over the bearing is pealing off, thus rotary movement is restricted, no free sliding motion. Honda doesn’t even know the flaw in the design. don’t know what kind of quality management Honda has.
I am not at all satisfied with honda's service, I don’t know why i purchased this vehicle, had a great respect over Japanese technology and was found of Honda, every thing is ruined, will never ever recommend any one to go for any kind of Honda products.
as Honda is in collaboration with hero motors, Honda opts the same design with them too causing the same problem. But hero Honda has slight modification to there pivot bushes.as well as price of spares parts is low when compared to honda spares for the same item.
please do not think that I am the only customer not satisfied, there are many but they don’t approach as they are frustrated, they just feel for it. There is no value for money when it comes to honda, honda is cheating us.
