Hey xristianos,
Thanks for the reply. I had a quick look and this is what I found concerning the rear mudguard in the ADR, section 42.:
42.12.3. Wheel Guards for L-Group Vehicles
42.12.3.1. General Requirements
The wheels of a vehicle and the wheel of a side-car must be fitted with wheel guards of width not less than the ‘Section Width’ of the tyre. The wheel guards must be so designed as to protect other road users, as far as practicable, against thrown-up stones, mud, ice, snow and water and to reduce for those users the dangers due to contact with the moving wheels.
42.12.3.2. Special Requirements
42.12.3.2.1. Rear ‘Axle’ and Side-car
The wheel guard provided for the rear wheel and for the wheel of any side-car must extend not less than from a point vertically above the foremost part of the wheel rearward to a point not higher than the intersection of the arc of the wheel guard with a line through the centre of the wheel at 45 degrees to a horizontal plane through the centre of the wheel when a mass of 45 kg is distributed in the saddle of the vehicle at its ‘Unladen Mass’.
Not sure if mu numberplate counts, but you might be on to something, it does pretty much give 45 degrees of coverage from horizontal!~
Also this:
42.12.1.2.1.2. the rear of the wheel guards must not terminate above a horizontal plane 150 mm above the axis of rotation of the wheels (as measured at the wheel centres) and furthermore the intersection of the edge of the wheel guard with this plane (point A, Figure 1) must lie outside the median longitudinal plane of the tyre;
I measured and there I think lies the issue. TECHNICALLY, a guard should be in place no more than 15cm above my wheel and the distance between my seat and the wheel is to great...HOWEVER, the numberplate does go back into the 15cm margin, so really, I'm only dirtying the underside of my seat, not the vehicles behind me, and who gives a crap about that! I suppose I'll ride it for a while and see if any cops give me the "no go".
If the ADR has been updated and I found an outdated one please let me know. I'm afraid my searching has turned up nothing more recent
Thanks for letting me know though, I think i will have second thoughts before putting a guard on the rear as although the solution I posted in my opinion looks better than stock...no rear guard looks even better
