I like the idea of keeping the passenger pegs, its the tie down spot for Gaint Loop bags among others. Soft luggage will be mandatory so having a secure spot to lash it to makes good sense.
No chance of "indenting" the tanks and having a handle for lifting (aka 690 rr) ? The "indent" seems easy, not sure how you'd mount a hnadle into it though, I'll leave those pesky details to you
Looking good, look forward to seeing the tail section.
