Great looking bike Bob, welcome! I like that model, the seating position reminds me of my S model. I can recommend the brake upgrade. That and the suspension are the best money I've spent on my SV.
I rebuilt an R6 piece I got off ebay. It was cheap-ish, but I spent a fair bit on the real-deal Brembo rebuild kit, making a nos piece from Partzilla almost worth it. The new part is $250 though, and by then you may as well spring for a real RCS19 for $100 more.Thanks Drewski! Which brake master cylinder did you go with, may I ask?
