KTM RC 390 Fuel Range: Capacity and Mileage Explained.

Okay, here’s my attempt at a blog post about figuring out the fuel capacity of a KTM RC 390, written in a casual, first-person style, and using basic HTML tags for formatting:

KTM RC 390 Fuel Range: Capacity and Mileage Explained.

So, I recently got my hands on a KTM RC 390, and one of the first things I wanted to know was, “Just how far can I go on a tank?” The owner’s manual is, well, let’s just say it’s not the most exciting read. So I decided to do my own little investigation.

First, I looked everywhere online. Forums, articles, you name it. It was confusing! some guys is talking about this,some guys are talking about that. I just want a simple answer!

My Experiment Begins

I started by completely emptying the tank. That was… interesting. I used a siphon pump – don’t try to tilt the bike, trust me! and put the fuel on my another bike. lol

Then, I got a measuring jug – the kind you use for cooking. I know, I know, not exactly high-tech, but it’s what I had!

I carefully poured fuel back into the tank, liter by liter, marking down each one. I was super careful to make sure the bike was level.

  • 1 liter…
  • 2 liters…
  • 3 liters…
  • …and so on…

I kept going until fuel was right at the very top of the filler neck – like, if I added one more drop, it would spill. And I’m serious about this.

The Result

My grand total? It was pretty to about 10 liters.

After that, I am confidently to ride my bike on road without worrying about running out of *

So there you have it. My completely unscientific, but hopefully helpful, guide to the KTM RC 390’s fuel capacity. I want my fuel, I get it!
