The RC51 was a very nice and underrated bike. I don’t know sales numbers but they seem rare. How stock is yours? I would imagine they sound very good with the right exhaust.
Mechanically stock other than slip-ons. I think it’s rated at 125hp, which is more than I could handle.
Cosmetically, the original paint really hid the nice lines of the bike. Way too busy. So I had it painted Ferrari red.
