#2 First tank experience with the new 107 Milwaukee-Eight engine

Part 2

How much does the new 107 engine consume in a street cruiser like the Harley-Davidson Road Glide Ultra?

I let it tingle a little and went deep into the reserve, the display had been saying “LO RNG” for a long time.

The tank has a capacity of 18.9 L plus the 3.8 liter reserve (22.7 L total).

Now I have used 21 liters of petrol for 369 kilometers, which makes an average consumption of 5.69 liters per .

I find the result impressive. If you look at the Harley-Davidson website, the fuel consumption for the Road Glide Ultra 2017 is 5.9 l/100 km.

We would like to see such honesty from car manufacturers, especially since the actual facts are not hidden from us anyway. 

“A consumption of 5.69L during normal driving is realistic”

Now what's more, on my last stage, everything was there except for driving at full throttle on the motorway. Together with two buddies on their Harleys, we drove to the North Sea on country roads, federal highways and an expressway.

The highest speed was briefly 140km/h, but mostly on country roads with normal driving. The tour wasn't designed to save fuel, but it's clear that if you put your mind to it, you can certainly do more with one full tank.

The engine now has 6,150 kilometers behind it, the break-in phase is long over and now the fuel consumption can also be taken into account. For some people it will certainly be interesting to know, especially if big tours are planned, you need these key data.

So far I'm excited about the new 107 Milwaukee-Eight engine, the 103 was actually good, but the new Euro 4 standard required these modifications and Harley-Davidson did a good job here.

The engine has become quieter, the sound is better again even without the standard valve and fuel consumption is low compared to the powerful bike. Perfect!
