Westly, the "general" rules has a restriction above 500mm, making the region above the tyre, but bellow 500mm allowed IMO.
Anyway, for constructive review / editing.....
T3.5.5 the angle of bend braces at less than 45 deg to the tubes bend plane will make the VERY common bent upper side impact tube solution illegal, or at least very wide. Is that the intention? Would it not make more sense to brace a bend perpendicular to the plane of the bend to support rotation of the tube about it's ends?
T6.5.9 Rack attached to frame - Some designs specifically feature unsprung mounted steering gear (ie beam axles). Is the intention here to ban such concepts? Or simply to ensure attachments are suitably strong/rigid?
I.C.1.7.1 Restrictor, supercharger, throttle ONLY - I understand the reasons for this change for the turbo designs, but with bypass/recirculation valves etc banned, this now creates a big issue for any positive displacement supercharger, which are quite happy to operate in partial vacuum. Would a propriety internal relief or bypass valve be considered illegal?
I.C.4.6 IC max voltage. This (60VDC/25VAC) is well below what is seen in the typical motorcycle charging system. Is the intention these systems are no longer permitted and on board charging deleted, or are to modified to comply?
