Installation of Neville Lush Racing "street" cams in 2014 Rocket III Touring

Things will change when we Brexit !
EU health and safety laws dictate tea breaks every 10 mins and quality control is carried out via drone from head office , lest anything dangerous is found ? That rubbing case was well within EU guidelines and tolerance !
