The original Harley-Davidson Fat Boy made a huge impact, enough to inspire a legion of lookalikes. This 2020 monster-truck reinvention re-establishes it. No Harley generates a bigger grin.

In fact,

The focus of the new Softail family is the all-new Softail frame (so-called as it hides the rear suspension giving a classic hardtail ‘look’) which now uses an inclined single shock, Yamaha LC style, in place of dual shorter units previously mounted beneath the transmission. The new tubular steel double cradle is also claimed to be substantially lighter, stiffer and comprise far fewer components. Three different head angles, two shock lengths and two widths of swing arm are also employed in a modular approach to create the eight different models.

In Fat Boy trim this comes with a 30º head angle and, most vividly of all, new ‘monster truck’ solid wheels that are the biggest news and the reason the 27-year-old Fat Boy has at last rediscovered its mojo. Dubbed ‘Lakester’, these wheels are not just bigger, they’re massive – larger in diameter as well as now comic-book broad. Both grow an inch in diameter while the front broadens from 140 to 150 while the rear goes from an already vast 200 to a simply gargantuan 240. So big, in fact, that you can’t help but smile. The ride is entertaining, too. In a straight line, though hefty, the steering is tolerable. But through the twisties it needs a significant, unsettling effort to tiller around and plenty of forethought. On balance, this isn’t a complaint: you attune over time after which the new Fat Boy is a massive grin and a unique pose.

As with three other members of Harley’s new Softail family, the new Fat Boy now uses the four-valve, partially oil-cooled ‘Milwaukee Eight’ 107ci V-twin, as introduced in its 2017 touring range, with the option also of the 114ci version. Both are modified for Softail use via a new oil cooler subtly positioned between the downtubes and, as they’re rigidly mounted in the new Softail frames (in the tourers they’re rubber mounted) come with two, not one, balancer shafts.

Along with the new frame, uprated engine and cycle parts and new equipment such as lights and clocks, the build quality of the new Fat Boy, and indeed all the 2018 Softail family, has been noticeably improved. The jury necessarily has to remain out on reliability as it’s simply too early to say as we write. However, with the powertrain being based on that of the proven ‘Project Rushmore’ touring family and quality seemingly raised throughout, we’ve little cause for concern.

Harley ownership never comes cheap and with prices starting at over £17K that’s certainly not changed with the updated and improved Fat Boy. On the positive side, the new Fat Boy is a massive grin and a unique pose and after years of its presence being diluted it’s good to see the Fat Boy back to its best once again.

Equipment

3 out of 5 (3/5)

Those monster wheels, new frame and uprated engine are joined by dramatic new LED headlights, stylish new clocks and more. OK, there’s still no electronics and little by way of luxury but it is a classy machine and Harley have noticeably raised their game.

Happy with bike they just need to up there game on the quality of fillings - (Harley, You need to look at Triumph Quality if you want to stay in the game), glad I got a good discount as like all Harley’s nowadays the value falls like a stone in the first two years.

Ride quality & brakes 4 out of 5

It’s a Harley, don’t expect comfort or brakes and you’ll not be disappointed!

Engine 4 out of 5

A Gem, with a Stage Two, and open exhausts, but not got the same impact as the Old Harley’s of 2014 to 2016.

Reliability & build quality 3 out of 5

The reliability has not been a problem, but the chrome on the bars and headstock needs improving, its very thin and full of tiny marks - it’s not got the quality of my 10 year Old Rocket.

Value vs rivals 2 out of 5

£350 for the first 1,000 mile service, absolute P**** take. Will use Indy when warranty expires.

Equipment 2 out of 5

You don’t even get a tool kit, so why expect Equipment!

Buying experience: Bought from dealer in Rutland, good discount, fair trade in + upgrades

Version: 114

Year: 2018

Annual servicing cost: £250

Fantastic riding experience, looks and sounds the business. You do need to ditch the standard pipes to get the Harley sound. I added a Vance and Hines Fuelpak to flash the ECU to get the sound and feel that I wanted. It made a huge difference to the standard bike. Handles really well for the style of bike and is very quick off the mark. Its surprisingly stable and vibration free once underway. I would suggest its not for an inexperienced rider as the wide tyres make it feel unwilling to turn.

Ride quality & brakes 5 out of 5

The ride quality is superb. I have a BMW R1200RT and I can state the Harley's mirrors are more stable at any speed than the BMW. The suspension is excellent and brakes are more than good enough.

Engine 5 out of 5

Stunning low down torque makes it pull from standstill. However you do need to use the gearbox more than you would think for such a large capacity motor.

Reliability & build quality 3 out of 5

After two years its never missed a beat. However :- The wheels are bare aluminium and so will need to be polished regularly, or coated in some way. Speedometer can suffer from condensation and the fuel filler cap can suffer from vibration due to incorrectly sized O ring

Value vs rivals 4 out of 5

After the first service I did it all myself. If your confident these bikes are really easy to work on and have self adjusting valves so just a question of oil changes for the engine.

Equipment 4 out of 5

This bike is all about the engine. It is fantastic to ride. I would recommend an aftermarket seat as the item supplied is useless for both pillion and rider. I have the HD hammock seat which totally transformed the ride in terms of comfort for both rider and pillion. Ditch the standard pipes and add a Fuelpak to remove the restriction necessary for "49 state compliance" which is how they ship them out.
