I know this must have been asked plenty of times before, but I'm new to this and haven't found anything about it in the search.

Where can I find a list and/or explanation of all of the letter sequences and what they mean?

For example. A Dyna 'FXD' or FXST, etc.

 

X- Sportsters. These descend from the K series, 1952-56
XL - Series started in 1957. They are "unit construction" (engine & transmission share a common case)
L- High compression (7.5:1 in 1957)
H- Starting in 1958 came the XLH, meaning Higher-power or High-compression (9:1) or Hot .
C- Also in 1958 was the XLCH. The C was intended to mean "Competition".
CR - Cafe racer style, with bikini fairing.
LT - Touring, with bigger tank, thicker seat, and hard bags.


The first letter of the model designator reveals the engine series :
G- Servicar three wheeler, 1932 to 1972
E- Overhead valve 61 cubic inch "big twin" (Engine/trans separated)
F - Overhead valve 74,80 or 88 cubic inch "big twin"
FL - 80 to 88 cubic inches and a fat front tire.
K- Side valve 45 and 55 cubic inch sports bike that replaced the WL in 1953 and was replaced by the Sportster in 1957. It had many design features that were carried over to the Sportster.
U- Side valve 74 or 80 cubic inch "big twin"
V- Side valve 74 cubic inch made prior to 1936
W- Side valve 45 cubic inch made 1934 to 1952
X- Sports and special construction. Applied to 1918-1922 opposed twin Sport, 1944 military opposed twin, and 1957 to present Sportster.

The second letter of the model designator reveals the Front end (except sportsters)
X- Narrow tire and sport forks.
L- Wide front tire and Hydra-Glide front forks.
(FX originally meant "Factory Experimental" The first one was the Super Glide FX)

The third letter of the model designator reveals the frame style:
D- "Dyna" frame (with the rubber mounted motor)

ST - "SoftailŽ" frame

The next letter(s) indicates the model bike within the frame family :
A- Military (Army) version (except GA, Servicar without tow bar)
B- Battery start (early models), Belt drive (early 80's) Black paint.(1995-6 model, the Bad Boy)

Then stop why dontcha....lol

 

The "D" in FXD is for "Dyna", the "ST" in "FXST" is for SoftTail. Not much, but my 2 cents worth...

 

Not my fault

Hope I didn't miss any

 

naw I think you pretty much covered it peppi, but it seems I remember reading that on the that the 'B' designation (in red) meant the TC88 'B' motor.

The way they throw some of those letters in here and there seems at times to make no damned sense...lol

 

Wow, very informative. Thank you.

 

Mike


"B" motors are in the later softails (rigid mount) and the dynas/baggers etc have the "A" (unbalanced or rubber mounted) motors.

Designations like the FXSTC (custom) or FXSTD (Deuce) and some others would throw you off using your "B" analogy. LOL
