Hi CWchan,
Sorry I noticed this posts is quite old, but I absolutely admire the work you've done on your CB550. Beautiful front end and wheels!
I also have a 78'' CB550 and is looking into putting a 2005 CBR600rr front end onto it. Was Hoping I could get some answers from you.
According to Rusty Olive, the stock CBR600rr triple and stem will just go onto the CB550 frame with perfect fit, all I need is the top and bottom bearings from AllBalls bearings. Was that the case with you? Also does the steering stop fits right for these two bikes, or will there be some adjustments needed?
Lastly, I saw your post about the CB550 ignition being able to fit the CBR600rr ignition holder on the top tree, and still have the steering lock to work perfectly. Is this the case? I know I probably be asking too much but do you mind showing me a few pictures of your ignition set up on your top tree?
I am very excited about this front end swap, sounds like everything will be in without too much hassle, only tricky part is the wheel hub.
Thanks a lot for your help mate!
