Not hard to find out. Just search specs for each year/model.

So, is the rake only different because of the triple-trees, or do the frames have different rake at the neck also?

I am fairly certain all necks are the same with the possible exception of the R.

I received the following from one of the other forums...

"A,B rake, frame 34°, trees 4°, total 38°
R rake, frame 30°, trees 2°, total 32°
D rake, frame 32°, trees 4°, total 36°
I believe the stock A,B shocks are 13" long"

I believe the F is also Less than the A and B.

How about the frame rails? On the same model, have they changed physically (besides the color) from year to year?

Most are forward controls and interchangeable. The R is a completely different frame but the front rails may work and the D has mid pegs, the rails would fit but the not have pegs and vice versa.

I can help with a specific question.
