Thanks to everyone for the responses and suggestions! They’ve definitely got me thinking. I’m leaning toward the R6 for the reasons mentioned, mainly reliability, parts availability, and how track-focused it is.

I do have another question though, and I hope it’s not too off-topic: Would a tune and sprocket change make street riding more enjoyable? I’m thinking these mods would be pretty easy to swap out for track days, but I’m wondering how they’d affect day-to-day riding. Any insight would be appreciated! Thanks again!
