1990s Harley-Davidson Fat Boy (FLSTF) Valuation Report

Date: August 2025

Historical Overview

The Fat Boy (FLSTF) arrived for 1990 with solid-disc wheels and monochrome “Grey Ghost” paint, becoming a pop-culture icon in the early 1990s. UK-market bikes through the decade used the Evo 1340 V-twin; collectors prize the 1990 launch “Grey Ghost” most highly. Well-documented UK auction results exist for 1990 examples, including Bonhams Stafford sales; later-’90s Evo models trade lower but remain desirable riders.

UK Valuation Summary (by condition and variant)

Condition	1990 “Grey Ghost” (Evo 1340)	1991–1999 Evo 1340 (all colours)	Example External Source (non-link reference)
Project / Restoration Non-runner or incomplete; recommissioning and cosmetics likely. Early 1990 bikes still carry a scarcity premium.	£4,500 – £6,500	£3,000 – £5,000	Bonhams – Stafford motorcycle sales; eBay UK completed results
Roadworthy / Presentable Running, MOT’d, largely stock with age-related wear; history improves confidence.	£7,000 – £12,000	£5,500 – £8,500	Bonhams – 1990 FLSTF Stafford (sold); Car & Classic – UK sold/auction listings; The Saleroom – multi-house results

Notes: Ranges reflect verified UK sold results where available (not asks). UK Bonhams Stafford sales include 1990 FLSTF examples; Hagerty records a Stafford 1990 FLSTF sale at $13,216 in April 2005 (≈£7.3k using period rates) and a UK Bonhams 1990 FLSTF trike at £9,775 (used here as directional only due to conversion from stock). International results are used for context only and converted sensibly to GBP when referenced.

Value Influencing Factors

• Variant & year: 1990 “Grey Ghost” launch bikes sit at the top; later ’90s Evo models trail.
• Originality: Correct solid wheels, stock finishes and uncut fenders/exhaust; reversible mods with OEM parts included help.
• Mileage & provenance: Documented ownership, MOT trail, import paperwork and full history raise confidence and price.
• Condition: Clean engine cases, straight tins and undamaged wheel discs are key inspection points.
• Venue & timing: Spring/Summer Stafford and well-photographed UK online auctions tend to achieve stronger outcomes than winter classifieds.

Conclusion

For UK buyers, the 1990 “Grey Ghost” commands the premium: presentable riders typically realise £7k–£12k, while excellent, highly original examples make £12k–£16k. Later-’90s Evo 1340 Fat Boys are more attainable, with roadworthy bikes around £5.5k–£8.5k and very clean, documented examples £8.5k–£11k. Originality, completeness and provenance push any bike to the top of its band.
