It’s a very nice bike by hero Honda I purchase the second hand Hero Honda Passion which is 3 yrs old though its mileage is best and it is in good condition.It is maintenance free. ran about 3800km till now.At the speed 50 to 65km/hr in city its giving 60 to 65kmpl and in long ride 70 to 80kmpl.
I think the mileage is depending on the weight you put on the bike, hero honda passion do work good on city road. Purchased it The bike is good for college students and also for small family(2+1). It is stylish world’s largest selling motorcycles, second only to Hero Honda Splendor. I recommended for this bike
