It's an interesting build, that's for sure.
A few comments,
Some stainless bolts in your calipers would look nice and be low maintenance, although I gather steel or titanium bolts are recommended for the mounting bolts.
I'm a little worried about the visibility of your rear indicators, tucked under the seat some 20" above road height. A signal might be missed by drivers, unless they are nice bright LED's?
Number plate mount is still to come I guess but a plate light will be needed unless you are only going for a daytime MOT?
Likewise a diddly reflector will be needed somewhere, sadly. I remember putting my 916 style tail unit on for a while, which I didn't realise is without any reflector. The good guys in the bike shop (sadly, now long gone), stuck a tricolour reflector on the number plate an then passed the MOT. Not sure it would happen in too many garages these days.
Good luck & keep the piccies coming please!
