I have this idea of putting together a thread which points out all the differences between the frames of the F2 and the F3. I actually have a bare 1998 F3 frame and a bare 1992 F2 frame. Unfortunately, I have to trash the F2 frame because I do not have the paperwork for it and nobody seems to have any interest. It looks like I'll have to just part out what I got with it and scrap the frame even though it's straight... what a waste

While I still have the frame, I wanted everyone to shoot ideas at me of what is and what may be different so that I can take a photo. This way, other people who don't have access to one or the other bike or certain areas of the frame may see what is different, and why certain parts may not be compatible.

I know that the ram air duct tab on the F3 is different as well as the swingarm width.. so what am I missing guys? Let me know before I have to junk it!

Differences:
- Ram-Air Duct Mounting Tabs

 

which one is lighter?

 

You know, that is a very good question. Unfortunately, I don't have what I would need to weigh either frame

 

I have my frame completely stripped, so I could tell you what an F2 frame weighs... cant help with the F3.

 

I believe the f2 and f3 frame is exactly the same, just has different parts attached to it. The f4 and f4i are also the same.

 

nope their alittle different.

 

tie a rope to both and hang them off a pulley (or similar)...

 

I sent a PM about the frame thanks.
