I bought Hero Honda Passion Plus Black Red varient in 2008. Since that time I drive it around 1, 20, 000 kilometers.
Still its running very nicely. I got an average around 60-65 kmpl constant. When I can not maintain I got around 55 kmpl.
When I go for long tour its quite uncomfortable. But average I got around 70kmpl.
I did engine work once after 80, 000 kms, after that it is running very well.
I recommend this to buy if you need good average and nice looks too.
