I stumbled upon this a moment ago...
CBR600 F2 F3 SWINGARM EXTENSIONS 1993-1998 8-10" | eBay

Now I have no interest in this for my personal f2 but I have seen a lot of people here ask about stretching their f2. One of my friends rides a gsxr with an 8 inch stretch and it just doesnt handle like its supposed to.

Might be a repost but whatever maybe it'll help some squid out LOL jk

 

Thats cool for someone who wants to drag their bike.

 

That's a bit of overkill for the F2, but hey why not...

 

Stretching is not particularly my taste, especially on an everyday bike, but I can certainly see picking up a pair to use at the dragstrip. I doubt I'd ever use much more than an 8" stretch, but I guess it'd be nice to have the option. Anyway, using something like this is far, far better than butchering the stock swingarm, IMHO...
