Or for a more objective viewpoint

The K1 GSXR is an outstanding machine.

Performance wise there is fuck all to seperate them in reality but the GSXR is a bit roomier.

The finish on the Yamaha is a little better tho (but neither of them are a Honda)

I would go for the GSXR but go look/sit on both and see which you prefer as there is next to nothing between them
