A handlebar bolt cover for Yamaha FZ6-N and FZ6 Fazer. I tried it with S1 model, but it might as well work for the S2.

Or even other models like the FZ1 or FZ8. Or even models out of the FZ series (tracer, MT, etc.). I wasn't able to check.

It looks awesome with silver color. It looks almos like the original one from Yamaha.

Print settings:

Orientation: Up. As if they were mushrooms.

Layer height: 0.12

Support: Yes. Normal.
