I have bought herohonda passion pro on 04.08.2011. it gives me mileage of more than 83kmpl .and look is super compare to other 100 cc bikes. many of people said passion pro gives worst mileage don’t believe them. I think they don’t know how to use bike. For good mileage ride the bike b/w 40 to 48 km/hr. don’t ride like 150 or 180 cc bikes it is 100 cc and designed for good mileage. in hero honda 100 cc bikes if u ride more than 60 km/hr u won’t get very good mileage. I suggest some tips to maintain good mileage.
Don’t go more than 48 km/hr.
Avoid sudden acceleration and brake.go with constant speed
Shift the gear smoothly and don’t go in lower gear except signals
Turn off the bike in signals (u can start ppro in 1st gear using self start with the use of cluth)
If u follow these tips u can get good mileage I suggest this bike those who want more mileage and excellent look . Dont buy those who want more power like 150 cc. This bike is value for money.
