I bought Bajaj Kristal three and a half years ago.
For two years it ran smoothly, after that it started giving problems -
Battery discharges quickly
Silencer very week easily getting holes in it
Silencer too costly to repair frequently and many more.
Re-charging battery is very difficult because of its placement inside the front bodypart
Generally I had to start the scooty by kicking.
The parts are also not easily available.
