Review of the 2018 Softails with New Frame and M8 Engine

First Look & Ride Review

2018 Softail Fat Boy

114 Cubic Inch Milwaukee-Eight




Check out the Video Report Below



Getting on the bike, there were two things immediately noticeable-

1.  The bike feels light...not as light as a Sportster, but substantially lighter than a pre-2018 Softail.

2.  There is no ignition switch.  There is a FOB, and the minute you push the Run switch on the controls, it is on.


The 114 Cubic Inch M8 Engine is smooth and quiet.  With gear driven counter-balancers, it is smoother than the Twin-Cam B engine.

It also has serious low end torque, and seems to keep pulling past where the 2017 M8's flattened out.

I was up to 90 MPH, probably in the time that my 103 Twin Cam might have gotten me up to 60 MPH...and it all happened very smoothly, without me even realizing it.


What is this?  Some folks may like it, but I was surprised to see the tried & true "locking" Jiffy Stand replaced by a this kickstand.


There is not a lot of plastic on the bike...but there is some.  And two different pieces need to be removed to get to the transmission filler & dipstick.


I will need to ride this new frame some more, but my first impression is that the monoshock suspension delivers a superior ride quality, and that the frame is much improved.  I did not experience any wallow while hitting the curves at speed.



2018 Heritage Notes:

After I had finished my two hours with the Fat Boy, the Dealership had just finished of their PDI on a Heritage. 

I spent some time looking it over, and could have ridden it, but I was so flummoxed by what I saw...not only did I not ride it, I completely forgot to take photos of it. 

It looks like the photo's on the HD site. 

It has the same frame as the Fat Boy, with the same interesting changes outlined above in the photos and video.

A couple of things unique to the Heritage:

1.  If you don't like the chrome studs on the seat and the saddlebags from previous years, it is doubtful you will like the black protrusions that have taken their place.  If you do like the chrome studs on previous years, it is doubtful you will like the black protrusions that have taken their place.

2. The saddlebag lids are amazingly flimsy, surprisingly lacking in rigidity.   The button to open/lock the saddlebag is up top, in a recessed plastic "cup".

Whether it is rain, or just washing the bike, it will make for a little pond.  It is all plastic, so it won't rust...but I am not sure it will not leak into the bag.


3.  The floorboards are narrow.  Again, I did not take photos, nor measure them, but they are at least 1" LESS wide than the standard floorboard width found on FLH models.

Here is a photo of the 2018 Heritage Floorboard-


Here is a photo of a pre-2018 Heritage Floorboard-


As noted in the video, on this new frame the floorboards sit higher off the ground/closer to the seat level, and with them being more narrow they may be comfortable for a smaller rider, but even at 5' 11", I felt very cramped.


4.  The Heritage has 4.4" of rear travel (as does the Fat Bob), the rest of the Softail line has 3.4" of rear travel.


A few more thoughts-

Like the Fat Boy, and previous years of the Heritage, it still has a 5 gallon tank.

It feels much lighter pulling it off the kickstand, and like the Fat Boy, it no doubt accelerates quickly and smoothly.

Unlike the Fat Boy, the seat needs to be removed to adjust the monoshock pre-load.


On all the new Softails, Harley finally made them with a "Tank Lift" and a Relocated Coil...from the factory.  Guess they finally learned that these changes reduce engine temps and rider buffeting.
