Just buy what ever year is cheapest. I have an 05 and bought the one that was 35 bucks i think. Works great. And yes the long clamp should work fine with it, the older style is sought after though for people who use gps etc to clamp onto the middle bar. I bet someone would just trade with you.
Anyone done this mod with the sw motech 1 inch up and back risers with no clearance issues??
I've seen FZ1 bar on here with 1" up/bk. Pretty sure I remember that it did not create any clearance issues and did not require longer lines.. easy mod.
As for bar year, I'd go 06 or newer. 05 and older FZ1 was a different generation.. not sure same bar was used on those.
