Frame bracing GPZ1100B1

Rene Botman from the Netherlands here.

Next step in our new project is to improve the frame stiffness
of our GPZ1100B1.
I am looking for tips, advice, documentation or pictures.
Thanks !

welcome to kzr and obviously a picture of your bike will be welcome.
the gpz1100 frame has many improvements and is stiffer compared to the earlier 900-1000 frames, all from lessons learned during the superbike racing days. Are you really sure you need the bracing?

I been road racing for the last 10 years and I still see a lot of people in the winner circle with stock, non braced frames (but surely good suspension).

just cancelling the engine rubber mounts for instance could help a lot with rigidity by making the engine contribute stifness. Would think twice before starting to add bracing, extra weight slows you down and the 1100 is already quite heavy!

This is a very popular kit for the Z frames. Your GPz will not need all of this, but it should give you an idea of what to focus on.

No need, it already is braced to match the previous years race bike. Invest in suspension and rear swing arm upgrade.
