Great write up and documentation on this.
I just ordered an Ohlins S46HR1CIS rear shock for my 06 FZ1. I have an 07 R1 with Ohlins TTX rear and R&T forks, so I am taking my R1 forks and having them serviced with some new valving and springs, and will be replacing the forks on my FZ1 with the R1 OEM forks, changing the rotor and calipers for the OEM rotors and calipers as well, upgrading the master to a Brembo 19RCS and doing some stainless lines. It's the one thing that I feel is lacking on the FZ1 after riding my R1 with full kit of brakes and suspension.
I have been enjoying the creature comforts of the FZ1 over the R1, but the R1 is built for the track and riding hard on the street, the FZ needs a bit of love for my 270-290 pound body, as well as getting my wife on the back with me. Overall, this should improve it all, and having the instructions to do the swap myself helps.
