Duuude, I LOVE the RC51. I'm hoping Honda will come out with another V-twin sportbike in the future. That bike sounds awesome. For me, it's hard to come by an i4 with an exhaust that I really like...but it feels like almost any exhaust mounted on a V engine, it just sounds amazing. Not sure if that means I'm a V engine kind of guy, but I, oddly enough, like quiet exhausts on i4 bikes haha. I guess I hear too many raspy aftermarket exhaust setups I'm not too fond of.
