Metric Parts/Service

The first two letters many times designates the type of front end (tire size).  FL indicates that the front end has the small diameter 16 inch rim with fatter tire (ie 130mm) more comfortable for cruising.  FX on the other hand says that the bike comes with a narrow (sportier) front tire. 

Other times the first few letters determines the model family.  XL indicates Sportster and VR says V-Rod. 

The third (and sometimes fourth) letters can indicate the model family.  For example the D stands for Dyna while the ST indicates a softail.

The letter(s) that follow the above further describe the bike and narrow it down to an exact model.  The WG indicates Wide Glide, F for FatBoy, S for Springer. U for Ultra, C for Classic or Custom, etc.   As you can see the same letter(s) sometime mean something different! 

One new letter introduced in the late 1990's is the "I" designation.  For about six years Harley offered many of its models with either carburetor or fuel injection.  Adding this "I" to the end of the model indicated that it had electronic fuel injection.
