Obviously no. LOL, It's a bike....that's the point.  It saves gas so I don't have to drive/ride like I need to save gas.

And while i struggle to get 20km/L on my 373cc on city riding, partly because I insist of banging on the rev limiter on every gear because the bike is underpowered...........even then, fuel saving is still 3x compared to when I was driving daily.

So getting 50km/L to me is the bike is running on air....
