I extracted 74kmpl from my dhoom 86cc engine which are called 78cc.
If you ride in 4th gear non stop without reducing or increasing speed and stopping Honda 70 will also do 80kmpl.
My normal consumption that day was 48-50kmpl.
And bro most bikes sold in Pakistan have this handle alignment issue. It's only noticeable when you notice it otherwise it doesn't affects.
I have dhoom 70 and piaggio both have same issue.
Don't know if it's some design element? Or flaw.
Seen countless cg/cd/cHondaz with minor alignment issue in handle.
