F2 suspension on a CB550
Hey guys,
This is my first post. Glad to be here, I'm a fan of Honda cycles.
I already have a '77 CB550 that I recently tore apart and put back together, and I'm not happy w/ the suspension and brakes. I want to graft something (front and rear)from another bike. I don't want a street fighter look.
I've been checking out early-mid 90's bikes specifically because the bikes I've been looking at in this era have a similar triple fork offset and a mechanical speedo drive. Small detail, but I figure it's simpler than trying to convert over to electronic, and I'd rather keep my speedo.
So that being said, I was wondering if you all could help me with some measurements.
1. Steering stem length and diameter. Is it tapered at all? What are the bearing sizes?
2. Triple tree offset.
3. How are the stock brakes? I take it they're phenomenal.
4. Rear swingarm pivot diameter. Width of the bolt. Width of the shaft the bolt rides in.
5. Total length of swingarm.
Bonus: weight of stock swingarm.
In doing all this I'd like to basically take the whole front end minus guages, lights, etc and put it all, brakes, wheels, the whole shebang on mine. I'll be welding on tabs for the rear shocks. This was another detail I like about this era of bikes, the non-braced top side of the swingarms. I'll figure out the rearsets, they look simple enough.
I'm doing it because it will be a productive use of my time and it will only improve my handling and braking. I can do with 50hp. Not touching the motor. Much.

Hey guys and gals,
I've been staying pretty quiet lately, been busy snooping for parts and such. So, I decided I'd give modding a go since I've got a good variety of tools (but no lathe, damn), and besides, I've got a spare frame to monkey around on.
I recently scored complete front and rear ends off of a '96 YZF600 for cheap. Got the rearsets too.
Here they are. The last one is of a CBR600 F2 swingarm. Just from preliminary measurements, the CBR would be the straighter swap, still might go that way. Still need a rear wheel and tire, as well as the pivot bolt for the swinger (answer your pm's). That YZF swinger is beefy!!

No updates as of yet. I ended up spending my dough on a killer deal for a VFR. Not to say I'm done trying w/ it, but just need to save up the dough for parts. And like I said before, the CBR swap might be the easier deal, given the measurements for the YZF stuff.
It just kills me that I got such a good deal on the stuff and now I might have to turn around and sell it all. Might.
So all I really have is the CBR F2 swinger, it's wheel axle, and the adjusters. If you know of anyone willing to part w/ a rear end, rearsets, etc, let me know.

Just wanted to pop in and put an update in here. Been busy riding the VFR!! But now things have changed. At first this rear end was going on a track bike, but I wasn't crazy about a 2.5" gain in wheelbase, so it's mockup on the race frame and transfer to the street bike.
Can anyone tell me exact sizes of the rear axle bolt and the nut? Mine are a little chewed up so I'm not sure. Someone really horked down on them and I can't break them loose. I think it's an F3 rear end. The pivot bolt has an approx. 17mm shaft that tapers down at the threads on the end.
