the Ariel Arrow engine was the same bore and stroke as the Super 6 and the GT380?
Also it had the same crank offset as the Super 6 (which gave better port scavenging) many years before the Super 6 emerged?

No? Fekkin thought not.

And same bore and stroke as the RD250, not uncommon to have a square bore and stroke in 'performance' 2 strokes Al.

Bollocks I cant stop this!
