Tested : KTM has refreshed the 390 Adventure from head to tail, and in its current guise, the baby ADV is more off-road oriented than ever before. We have had an opportunity to spend a fair bit of time on the new 390 Adventure and here’s how much mileage it we are getting in the real world.
Fuel efficiency of the KTM 390 Adventure in real life
Following our script, we first did our highway run with the 390 Adventure for 53.7km, after which it took 1.79 litres to top off the tank, arriving at an efficiency of 35.50kpl. We were about to get the city mileage on the busy streets of Mumbai. Following a smidge over 50km driving run, it took 1.86 litres to top the tank up to the brim – that’s 26.94kpl.
KTM 390 Adventure mileage test
The engine and internals are carried over from the 390 Duke but the Adventure boasts a bigger rear sprocket (three teeth larger) which means a shorter final drive ratio.
But it’s not overly happy at low revs around town, although it seems a bit less grumbly than the 390 Duke’s engine, probably thanks to its more closely spaced ratios. The Adventure weighs another 14 kilos, so it is unsurprisingly lower on its efficiency figure than the Duke.
It has a higher 35.50kpl FE number on the highway compared to the 390 Duke despite the additional weight. This is probably due to the short gearing, as the engine is kept in its sweet spot when you’re cruising on the highway.
Fuel-efficiency testing by Autocar India
First, we fill the tank as full as we can and make sure the bike is wearing the manufacturer’s recommended tyre pressures, our fuel-efficiency testing procedure begins… We then ride the bike on fixed city and highway routes, where we uphold average speeds that are representative of the real world, as well as obeying speed limits. Rider weights and ballast are used to keep the payload on the bikes consistent, regardless of the vehicle type or rider. At the end of the test cycle, the fuel tank is filled to the brim once again to give us an accurate representation of how much fuel has been consumed compared to trip meter reading.
