You are correct DrTerry. Mike Savva raced an HD X2 Premier at the Easter Bathurst meeting in 1966 (see below). You can see he's pretty busy winding on opposite with that large thin-rimmed wheel and how-many-turns lock to lock! If anyone's interested, this image is from a Racing Garage story I wrote for the Shannons Club about the HD/HR X2s in competition: https://www.shannons.com.au/club/news/racing-garage/hdhr-holden-x2-the-generals-mysterious-1960s-muscle-car/
