it's RM250 including installation right? if live in Klang valley where petrol stations are like everywhere, that extra 1 liter seems not really worth it for me. at least 7 liter tank then I might consider
The way I see it:
For a 4L tank, every 3~3.5L you go refuel; for a 5L tank, every 4~4.5L...
3 x 4 = 4 x 3, for every 4 stops, you save 1. Hence, 25%
3.5 x 4.5 = 4.5 x 3.5, for every 4.5 stops you save 1. Hence, 22%.
My bike is 5L. I fuel up every 150km for 3.5~4.5L depending on how I ride.
If it was 4L, I would have to fuel up every 120km.
Depending how often you fuel up, you could save precious time.
