Quote from: Millietant on July 27, 2023, 06:25:03 PMI don't understand what you're asking here - why would people swap the yokes for FZR 88/89 but keep the rest of the FJ front end ? Am I missing something, or have you made a typing error?

I swapped a whole 1992 FZR1000 USD front end into my FJ (but with early R1 blue dot calipers and a FZ1 brake master cylinder).

It was quick, easy and I love it.

The tees fittwd straight in? Fj or fzr pin?


The FZR trees use exactly the same pin (stem) as the FJ, so they fit straight in.

On the USD FZR front end swap, with (2001/2005) FZ1 risers and handlebars fitted, there's a little bit of work with a hand file (takes less than a minute) and to the lock stops, to fit the lot. The whole conversion from start to finish, involves no special tools, just a basic hand tools and a drill

'89 FJ 1200 3CV - owned from new.
'89 FJ 1200 3CV - no engine, tank, bike for the future.
'88 FJ 1200 3CV - complete runner 2024 resto project
'88 FJ 1200 3CV - became a race bike, no longer with us.
'86 FJ 1200 1TX - sold to my boss to finance the '89 3CV I still own.


Thanks Dean - you provided the solid answer on why use the FZR1000 yokes.

The width is correct for YZF600 wheel and brakes, and the offset and stem are both correct for the FJ1100/1200
