Harley Fat Bob Vs. Fat Boy: More In-Depth Discussion:

There’s nothing like the Harley-Davidson Fat Boy, equipped with a Milwaukee-Eight 114 engine and Lakester wheels made of solid aluminum. Fat Boy’s 30th Anniversary was tested by many people last year and is practically equivalent to Fat Boy 2021- it has a few cosmetic changes.

The latest Fat Bob from the Softail family is long, low, and imposing, as it has been completely redesigned in recent years. This model was a combination of the Softail and Dyna families with an improved Milwaukee-Eight engine. For Harley’s 115th anniversary, both in 107 and 114.

Features

Fat Bob’s accelerated and decelerated more progressively through its closed-loop ESPFI system. Despite being mainly used to operate, the 6-speed Cruise Drive transmission makes the most of the ample torque and helps to reduce gear changes. Models of the Dyna series are constructed of steel tubes with a thick, rectangular backbone which provides some degree of rigidity.

Among the Softail lineup is the Fat Boy 114, which is a member of the Slim-line. Therefore, all Softail models have a vintage hardtail frame style. This bike features modern amenities such as Showa Dual Control Valve Forks and a mono-shock with an adjustable spring preload. There are also chrome fork covers on the ’21 model.

Engine

Fat Bob was available in two formats when it was launched – 107 and 114. Milwaukee-Eight engines have a displacement of 1745cc or 1868cc in inches. Currently, the larger 114 is the only engine available. The vehicle’s fuel efficiency is 47 mpg, and its left and right angles are both 25.6 degrees.

The Fat Boy is built around the corners with a rigid steel frame, thick 49mm fork legs, and a chassis designed to handle the corners well. Dyna gives you 98.8 ft/lbs of torque from its Twin-Cam 103 V-Twin engine. Featured chrome drag-type handlebars with a 1.25-inch diameter and black risers are internally wired. With a fuel economy of 47 mpg, the left and right angles are usually 25.6 degrees.

Comfortability

Ride the Fat Bob, and you’ll be surprised at how comfortable it is. It looks thin, but it’s incredibly supportive and comfortable. It has well-positioned handlebars and beefy grips (like the rest of the bike). It gives you a great sense of heft, as well as giving you a handy lever for turning the bike. Whether they’re too short or too far inboard on the handlebars, the stock mirrors on the Fat Bob are too short. To see more than my shoulders and forearms, you can spend more hours joking around with them.

Starting with the now chrome LED headlight nacelle, the Fat Boy 114 has a commanding appearance when it arrives on the scene. Solid 18-inch aluminum Lakester wheels return, mounted on massive 240mm front and 160mm rear tires, which are enhanced by trimmed fenders. As an added touch, there is a “bullet hole” chrome console on the console that represents the 5-gallon fuel tank.

Power

Fat Bob’s engine is capable of 94.00 HP peak output, a torque peak of 155.00 Nm (114.33 ft-lbs or 15.8 kgf-m) at 3000 RPM. It receives 119 pounds-feet of torque from its 1,584cc V-twin engine, a shotgun with 2-into-2 offsets, and a catalyst-equipped exhaust. This large-displacement, air-cooled twin features a matte black paint job and polished fins.

This Harley-Davidson Fat Boy is equipped with Milwaukee-Eight’s 114 V-twin engine, a 6-speed transmission, and a claimed 119 ft-lbs of torque. The Fat Boy’s 2-into-2 offset shotgun exhaust is now chrome, along with a chrome Ventilator air filter that proudly displays the 114 badges. In addition to these changes, the new Fat Boy includes polished or chromed engine covers and rocker covers, replacing satin chrome finishes from the previous model.

Price Comparison

Finally, there is a difference in the price of about $2000 between the two. It costs $18,799 to purchase Fat Bob, while Fat Boy costs $20,599. In Vivid Black, the 2021 Harley-Davidson Fat Boy costs $19,999. For an additional $400, you may also choose Deadwood Green and Black Jack Metallic, as well as Vivid Black or Gauntlet Gray Metallic (additional $750). Harley-Davidson models, like all other motorcycles, have a price tag that is very much determined by condition, mileage, and accessories.
