I wanted to start a thread on this so that it is easy to access if there are any questions about the differences between the 3 and what parts match and which do not. From what I have learned these are some of the differences and correct me if I am wrong.
Swing arms
-Bolt up on all 3 models
-S and E models do not have a chain guide like the SM models do
-SM has different caliper mounting than S & E
Subframe
-S & SM models are the same (have mounts for fender/racks and are longer)
-E model is like the S & SM but shorter (no mounts for fender/rack)
-All 3 will bolt up to any 400 frame
Rear Brake lever
-S & SM Models have a tab for a brake switch
-E Models have no tab for a brake switch
-All 3 will bolt to any 400 frame
Engine
-E models
-12.2:1 Compression
-Stage 2 cams
-Larger Carb
-S & SM
-11.3:1
-Stock Cams
-Smaller Carb
Suspention
-SM has different size triple clamps, larger inverted forks, stiffer rear spring
-S & E have same size triple clamps, smaller forks, softer rear spring
This is all I can think of right now and need to get going so correct me if I am worng and please ad any other info you know.
