Can it actually deliver on KTM's 400km range claim? Here's your answer…
I recently put the KTM 390 Adventure X through a proper highway mileage test, and the result turned out to be quite interesting.
To keep things accurate, I followed the full-tank method, which means filling the tank to the brim before starting and topping it up again after completing the ride. This ensured a precise measurement of the fuel used across the entire journey.
Test Route & Riding Conditions
The ride included a round trip from the outskirts of Pune to Satara, covering close to 160km. This route offers a bit of everything: long, open highway stretches, a few twisty sections, and light traffic in patches, making it ideal for simulating real-world touring conditions.
Throughout the ride, speeds were kept steady between 110-120kmph. Throttle inputs were smooth, and braking was kept to a minimum to replicate a typical long-distance highway run.
Real World Mileage
At the end of the test, the KTM 390 Adventure X took in 6.25 litres of fuel to reach full capacity again. Based on the distance covered, this works out to a real-world fuel efficiency of 24.94kmpl.
Considering the bike was ridden at relatively high speeds, this figure is quite respectable. With its 14.5-litre fuel tank, the motorcycle can deliver a theoretical range of just over 360km on a full tank under similar riding conditions. KTM, however, claims that the bike is capable of covering over 400km on a full tank under ideal riding conditions.
What You Can Expect
If you dial things down and cruise between 80-100kmph, the KTM is likely to return better efficiency figures, somewhere in the range of 25-30kmpl depending on how you ride.
Of course, factors like traffic, terrain, wind resistance, and riding aggression will influence the final numbers. But overall, the bike offers a decent balance between performance and fuel economy for highway touring.
BikeDekho Says
A real-world mileage of 24.94kmpl is fairly impressive for a performance-focused ADV like the KTM 390 Adventure X, especially when ridden at triple-digit speeds. While efficiency isn't its strongest suit, the bike still manages to offer a usable touring range without compromising on its fun-to-ride nature. All said and done, we also tested the mileage of the Royal Enfield Himalayan 450, and the bike surprised us!
