Spot the difference... (yes, the z4's pointing the other way!)
New, shorter fork stanchions
Fork legs, yokes, and rear caliper carrier now bare ally
Discs cleaned up and new fixings.
SP3 footrests with pillion pegs.
Black plug caps instead of red ones!
At least the front end doesn't look like a black hole now
You can't see:
Electrical rewire of front end
FAC dampers in forks
New brake pads, wheel bearings and steering head bearings
