presentation of the 1690 SOFTAIL FAT BOY SPECIAL FLSTFB 2012

the Fat Boy is certainly one of the best-known and most emblematic models in the Harley-Davidson range. 20 years after its appearance, a twin brother appeared in 2010, the Fat Boy Special. Presented as a novelty, this model is more like a Fat Boy dipped in a tub of black paint, with only the exhaust escaping from the drowning. In fact, it goes a little further for this big softail that's trying to join the Dark Customs family. In terms of finish and refinement details, the Twin Cam houses black between its cooling fins, but lets chrome invade the rest of the mechanics. The stainless-steel "mini beach" handlebars are narrower but larger in diameter, housing the electrical cables inside. The full rims are also covered in black, except for the rim. Same treatment for the headlight, exhausts and fork, dark as night, then finished off with a touch of stainless steel. The seat has been hollowed out by 10 mm, allowing the new handlebars to merge with the bike (according to the manufacturer). This Fat Boy Special is not so much a new model as a 'trendy' version. For 2011, ABS is now standard. And from 2012, an even bigger engine justifies the name. All Softail models, including the Fat Boy Special, are powered by the beefy 103 block. This Twin Cam brings 1690 cm3 of displacement, a few more horsepower, and a nice slice of torque of over 13 mkg. Maximum torque of 132 nm is reached at 3250 rpm. The FLSTFB is equipped with new handlebars whose curvature has been revised for greater comfort and improved ergonomics.

Roule Nickel Stage 1: responsive and firmly planted on the ground. This machine is a powerhouse. The only downside is the LED strip on the fuel tank, which burns out easily. Fuel consumption: 5 L/100 km
320 km on a single tank Rating : 4/5

French Model 2012
i've owned a Fat 1450cc, and there's nothing like it: great power, lots of torque, improved comfort thanks to a very good seat (new hollowed-out saddle), the handlebars have been moved closer together, so you get a better grip on the controls, and you don't get tired at all, your arms don't pull any more! behind with a Sissi bar, and the 180 tire which absorbs road vibrations much better, Madame doesn't complain at all! a real pleasure this bike is for cruising, and fishing for pleasure! if you still have any doubts, don't hesitate any longer, enjoy the ride! Rating : 4/5
French Nini2a Model 2013
You have to realize that you're sitting on an engine and you're moving it

A sort of retro pleasure, big engines big noise big feeling Rating : 5/5

THE 1690 CM3 PUSHES HARD
IT RUBS IN ROUNDABOUTS SO YOU HAVE TO CALM IT DOWN!
I'M THINKING OF EQUIPPING IT WITH SISSYBAR AND WINDSCREEN AS IT'S OFTEN USED AS A DUO.CORRECT BRAKING WITH ABS THAT KICKS IN EARLY.VERY NICE LOOKING BIKE IN MATT BLACK WITH BLACK FORK/BLACK SCREAMING/SMOKED BLACK TURN SIGNALS/WORM-ORANGE SPEAKERS
