FLSTF
The Harley-Davidson Fat Boy, is a V-twinsoftailcruisermotorcycle with solid-cast disc wheels.[2]. Designed by Willie G. Davidson and Louie Netz, Harley-Davidson built a prototype Fat Boy in Milwaukee for the Daytona Bike Week rally at Daytona Beach in 1988 and 1989.[3][4] Fat Boys produced from 1990-2017 are coded FLSTF, and FLFB (& FLFBS) from 2018.
The name is said to come from the bike's 'massive presence', and that the name gave a link to the earlier Harley-Davidson 'Fat Bob' model.[5][dead link][6][unreliable source?][better source needed]
History and development[edit]
The Fat Boy's frame is derived from the 1984 'Softail' which appears to have a rigid hardtail chassis but which in fact has a swinging arm with concealed springs that was originally designed in a Missourian garage in the 1970's by 'a mechanical engineer' named Bill Davis and later Patented in 1976.[7]Willie G the grandson of Harley-Davidson co-founder William A. Davidson originally turned down engineer Bill Davis' softail concept; but the company later relented, buying the rights and designing its own softail frame in-house.[8]
- After 1994, the exhaust was made seamless.
- In 1996 the master cylinder and switch gear were revised.
- In 1999 a new 1,450 cc (88 cu in) Twin Cam engine for the 2000 model year was used. This necessitated a bespoke engine variant and changes to the frame.
- In 2002 bullet-style indicators, alarm and immobilizer were added.[9]
- In 2005 a 15th Anniversary version was sold, with a 'Screamin' Eagle' engine, special paint and custom wheels.[9]
- In 2006 the displacement was increased to 1,584 cc (96.7 cu in)[9] and the transmission changed six speeds.[8]
- The 2010 'Fat Boy Lo' FLSTFB had the lowest ever Harley seat height.[2]
- In 2012 the Fat Boy received the new 1,690 cc (103 cu in) Twin Cam engine along with the rest of the softail range*
The 2018 Fat Boys have a redesigned softail frame with Showa front and rear suspension and new twin-counterbalanced Milwaukee-Eight engines. The two 2018 variants comprise:
- The FLFB 1,746 cc (107 cu in) with 109 lb⋅ft (148 N⋅m), and
- The FLFBS 1,868 cc (114 cu in) with 119 lb⋅ft (161 N⋅m)[10]
The 2018 Softail frame has a modified swingarm with a Showa rear monoshock suspension mounted beneath the seat (replacing earlier twin shocks). So as to provide a more comfortable and better controlled ride with improved handling, the front forks contain a Showa 'Dual Bending Valve' (SDBV),[11] a cartridge simulator using two valves to control compression and rebound damping, giving linear damping characteristics proportional to fork stroke speed. Harley-Davidson claims the 2018 chassis is stiffer and lighter than earlier Softail and Dyna platforms.[12] Further upgrades include an LED headlight and 18-inch “Lakester” rims, with wider 160mm front and 240mm rear rubber.[13][14]
It is one of Harley-Davidson's best selling models, and has appeared prominently in a number of TV shows and movies.[3] The Fat Boy 'earned a place in American pop culture' after appearances in the movie Terminator 2: Judgment Day. One of the motorcycles used in Terminator 2 is displayed at the Harley-Davidson Museum. It appeared again in Terminator Genisys.[2][15][16][17]
