I have been using it since last 5 years and found no problem so far. I run it 300 KMS (appx) every months, then service it . After servicing it becomes new again. Except color, nothing has changed in this bike.
Once after purchasing in 2007, I have faced challenge with its silencer, something like resins were coming out from it . But after I got it changed I never faced any other major issues with it . Later I found It was a manufacturing fault with many bikes in that batch.
Good Bet !!
