if its 500-750cc then its gotta be a twin. no one in the modern world would want a 500+cc single would they? so pimp up a RGS? tho unit obviously. whatever it will be just stick the goldstar badge on it coz who cares about the 1950s except people like us. and BTW i hope it has discs (lots of them), upside down forks, single rear shock, ABS and is batshitcrazy fast. if I was to buy a new bsa it would have to out-everything a new triumphs and hopefully the new nortons too, else what's the point? I'll use my a10 for the sedate weekend rides so don't need a modern replica or a deliberately out of date enfield clone for that.
