Useful thread this.
There's much talk of 'harmonising'

MOT / TUV type tests over the entirety of the EU.
The TUV is often cited as the best standard and the one to go for.
IF a test can be proven to lessen the chance of technical failure of a part / Bike - we'd be mad not to welcome it.
But it has NOT been proven.
Also, crashes due to technical failure as actually extremely rare (approx 1%) and so far the only ones to gain from a test are the testing body that does the test!
The EU really wants this to happen despite countries with no RWT (RoadWorthiness testing) having crash stats with no discernible difference to those that do not have one!
