2ND LETTER – FRONT END SIZE (EXCLUDES SPORTSTER, V-ROD, STREET & REVOLUTION MAX MODELS)

H – HEAVY-DUTY FRONT END (e.g., FLH)
L – WIDE FRONT TIRE AND HYDRA-GLIDE STYLE FRONT FORKS
T – TRIKE-SPECIFIC FRONT END (e.g., FLHTCUTG)
X – NARROW TIRE AND SPORT FORKS

NOTE: Street models (XG500, XG750) use “G” as a second letter, but it refers to the Street’s own Revolution X engine, not front-end size. Treat Street like Sportster/V-Rod/Revolution Max and skip this table for those models.

3RD LETTER – FRAME STYLE (4TH AND 5TH LETTERS FOR SOFTAIL, ENGINE SIZE FOR XL)

C – CUSTOM FRAME (e.g., FXCWC)
D – DYNA
H – HIGHWAY
R – RUBBER-MOUNTED FRAME (e.g., FXR)
ST – SOFTAIL
T – TOURING
883 – SPORTSTER
1200 – SPORTSTER

NOTE: Since 2022, Harley has also reused “ST” as a factory performance/Sport-Touring trim on non-Softail models — Road Glide ST and Street Glide ST are Touring-family baggers, and Pan America 1250 ST is Adventure Touring. Only the Low Rider ST is an actual Softail. “ST” alone no longer reliably means Softail fitment — check the family name first.

NOTE: Street and Revolution Max models (Pan America, Sportster S, Nightster) don’t use this 3rd-letter frame-style scheme at all. They’re structured as [engine][family] + displacement + trim suffix instead — e.g., RH1250S, RA1250ST.

4TH LETTER – SPECIFIC MODEL FEATURES *5TH LETTER FOR SOFTAIL, AFTER ENGINE SIZE FOR SPORTSTER
