Front Subframe

Hi all, sorry there hasn't been many posts lately. The plan was to have the bike finished this summer, but from falling pretty ill, making many visits to the hospital, and being told not to lift anything remotely heavy, all kept me away from the bike :( I did however manage to get a few more mods completed.

The new look for the bike proposes a new front cowl and headlight, both to which need to be mounted to a front subframe. The vfr front subframe wont support the new additions so a frame needs be created.
Mindful considerations for the build are that it needs to have a mounting point for the new headlight, new front cowl, current relays/sensors/instrument panel, and also allow for complete uninhibited movement of the cbr1000rr front end.

The way i went about making the part was to go step by step, allowing one aspect to fit/work, then adjusting/re-modding it to make another aspect fit/work, and so on...
So first i worked with the current subframe trying to fit it to the frame and allowing full movement on the front end. As the fireblade has much lower down handle bars, there was a problem with the front brake&clutch lever making contact with the instrument cluster, and full lock couldnt be achieved. And so the the front subframe needed to be extended out. Simple solution was to make a bracket...

plastic mocks to attach

fitted, checking positioning
final design draft
Brackets made :)
