I went with 17/43. And yeah, a Speedo DRD is pretty much mandatory because the resulting total 11% error will drive you nuts.
This gave a nice bit of added poke down low, while moving 6th gear into a more reasonable speed range while keeping it long-legged for the highway. In 6th gear, I'm turning right about 5,000 rpm at a true 80mph, and it's smooth from 70 on up. With stock gearing, 5th gear is kind of rough and jerky at anything below 80mph, with not a lot of passing power on tap.
I'm not sure if we've ever run a survey, but I think 17/43 might be the most popular choice.
I'll agree that 530 chain is well worth the minor added cost; you get significantly longer life. It's a heavy, torquey literbike, so it's tough on chains. I wouldn't exactly call 525 chain "marginal", but 530 chains on a Vee usually get you roughly 1/3 to 1/2 times the miles at least.
I've had the best luck with JT and Sunstar sprockets. I've had "Driven" brand steel rear sprockets that wore out unacceptably early.
No idea what chain length my bike is wearing. I've always found the best pricing on 120 link chains, so that's what I order. Then I cut off the unneeded links after testing length on the bike.
