I purchased yamaha libero G5 in november 2006 from Naman Auto Sales and Services located in Panvel, New Mumbai.But within a time span of just one and half year the steel parts of my bike including the handlebar, jumpers and accessories got junk on the surface( corrosion).I contacted the service engineer and the show room operators but did not get any satisfactory reply or remedy for my problem. Please help me out.
