Today, I went to one of the major showrooms (Naseer Suzuki Motorcycles, Saddar) and had a discussion with the representative there.
I told him that it is really disappointing that Suzuki bikes especially GS-150 is coming with lots of faults and people are suffering a lot. I mentioned almost all the issues come across me.
In reply he mentioned that Pak Suzuki is selling bikes with different grades. Dealers who are selling at low price than the company price has the major proportion/ratio of faulty bikes. Dealers get bikes with quality grade like D or E on lesser purchasing price and hence are selling on lower prices.
The showroom guy mentioned that whenever a fault found during quality control, company instead of sending the faulty part back to Japan, Taiwan or to vendor whatever, company present these bikes for sale at lower prices and dealer get them.
He did mention that he hasn't received a claim for last one year for GS like of faulty cdi units, faulty coil, faulty rims / misaligned.
