You can also note the consumption to detect wear or other problems earlier. Transmission belt, air filter, tire pressure, spark plug, ...
You don't need to ride a SH300i to be interested in such matters. But of course you may. Go ahead!
Just like that I don't complain that our car needs more fuel than a Toyota Prius.
On the other hand it is compatible to Euro-palettes and has 3m³ cargo capacity. Just push the 125cc scoot upright inside.
If you complain - buy the Prius.
