HI
I AM VIKAS., USING PASSION PRO FROM 2012 AND I FIND IT BEST BIKE FOR ME. BIKE IS FOUR STROKE, ITS ENGINE IS POWERFUL 110CC. THE BIKE IS SELF START AND ALSO BIKE IS AIR COOLED.MILEAGE OF BIKE IS 84 KMPL.BIKE IS AVAILABLE IN EIGHT DIFFERENT COLOURS IN MARKET. I THINK SOMETIMES IT HAS GEAR PROBLEM. BIKE IS VERY COMFORABLE AND LOOKING GOOD. ITS CONTROL IS EXCELLENT. SOME MINOR PROBLEMS EXISTS BUT IT IS AN EXCELLENT BIKE.
