Google says the ban was '88? The 20/20 TV report seemed to be a watershed moment for opinion... which was 87 according to youtube..
Among our family and cousins etc, we had 200E/200s/200m. Even tho he ended up with a 200m, I remember an uncle saying in '83 he would probably get a Suzuki quad cause they were "safer and have reverse" ... Pretty sure people questioned their safety very early on..
