This is my true experience with this bike. I owned Passion plus in 2004 which I sold in 2006 after 28k kms. Milage was between 55-58 kmpl city drive in New Delhi. Again bought Passion pro in 2012, after 6 yrs bike is still same to ride .Looks have however changed a lot. Getting 58-60 kmpl after 5000 km in Delhi and NCR.
Buy this bike for certain reasons:
1) you are not style crazy.
2) You are looking for less power and more mileage
3) You are looking for less maintenance bike.
4) You should not compare with upper segments bike.
If you match this criteria then you should go for this bike. Engine life is very good as it is based on very successful engine, nice digital meter, nice seating position, Very good ike overall.
