Harley-Davidson first launched the Fat Boy in 1990 and it has since become one of the brand’s most popular motorcycles. To fully understand its evolution, we must first look at the history of the motorcycle, what it is, how it came to be, and how it has changed over the decades.
From concept to a production model
The first Fat Boy prototype was designed by Louie Netz and Willie G. Davidson. They saw fit to define their signature look with solid cast disc wheels at the front and rear. The fenders feature a soft flash and made excellent use of shotgun exhausts, which was a first for the brand. The concept that would serve as the foundation for the new family in the Harley lineup underwent extensive testing and many customer feedback to prepare it for full production. It took two years of adjustments before Willie was satisfied with the end results. In both 1988 and 1989, Willie rode a prototype of the bike to Daytona. The bike was introduced as a production model available for sale to the public in 1990.
The 1990 Fat Boy was introduced to the world in a silver monochromatic paint scheme with a silver powder coated frame. To add a remarkably attractive contrast, yellow details were used. To give the motorcycle a handcrafted look, the fuel tank and seat featured lace-up detailing and was crowned with a unique logo that was intended to create a sense of nostalgia and patriotism, and this same logo has appeared in all editions. of Fat Boy produced. .
What is the Fat Boy?
The Fat boy is a softail cruiser type motorcycle. Many people wonder how he got his name. The term was given to the motorcycle due to Willie’s interpretation of its enormous size. It is also a name that links the motorcycle to the Fat Bob model that was previously made with similar DNA. To further explain the term “softail”, it describes the appearance of a rigid rigid chassis that is designed with a swing arm and has hidden springs. Refers to the type of frame. The Softail frame concept was purchased from their engineer Bill Davis and is an in-house product that is currently designed by the Harley-Davidson team.
The FLFB manufactured from 1990 to 2017 was powered by a Twin Cam V Twin engine in 1,340 cc and 1,584 cc. The Milwaukee Eight would make its appearance in 2018 with 1,746cc and 1868cc.
The first changes to the Fat Boy
The exhaust was the first thing to be changed for the 1994 edition of the Fat Boy. It was equipped with a new seamless exhaust that gave it a cleaner look. This was the only major change that was made during the year, but it really was all that was needed.
Harley-Davidson engineers overhauled the switch and master cylinder in 1996. This was the only real change made since overhauls in 1994. This would be the state until 1999, when the team would do it again.
It wasn’t until 1999 that a new 1,450cc twin-chamber engine was introduced to the Fat Boy.
Moving into a modern era, while retaining nostalgia for the past, Harley added a few innovations to the 2002 Fat Boy, including a bullet-style alarm, immobilizer, and gauges. This would help everyone until more were published in 2005.
2005 15th Anniversary Fat Boy
This special edition came out with an engine called the “Screamin ‘Eagle” along with custom wheels and special paint.
2006 Harley-Davidson Fat Boy
The Fat Boy received an update in 2006 with a 1,584cc twin-cam engine that was larger and was paired with a six-speed gearbox.
2010 Fat Boy Lo
The only substantial change in 2010 was the addition of the Lo, which featured the lowest seat height Harley-Davidson had ever produced.
The Fat Boy is still alive and well in 2018 and comes in the form of a new redesign on the Softail frame that includes Showa front and rear suspension that replaced the twin shocks with a new monoshock installed under the seat. It offers better ride control along with greater comfort.
along with the addition of the new Milwaukee Eight counterweight engines available in two variants.
