You can actually find high quality 520 chains that are lighter than some 420 series chains. Some non-o ring motocross chains and the chains designed for 250gp bikes come to mind. I researched the weights and bought a DID ERT2 chain last year and it had noticeably less drag than a typical o ring chain. It did require more maintenance though. Plus the added benefit of not having to buy special sprockets.
This is coming from someone who has been almost fanatical about saving weight off a racebike. Currently my Ninjette weighs about 285lb.
