Twins Kick ASS!!
Love 'em or hate 'em is right! Riding a twin takes a little different riding style. You have to be a little smoother with the gears and throttle. this is especially true when setting up for corners. I came from in-line 4's, myself. I used to be big on engine braking before a turn, rather than using the brakes to scrub speed. My Hawk put an end to that! The first time I did that, the back end came way around! Twins are also less forgiving if you are roll on/off/on the gas. Some people either don't like. or never adapt to them. Most twins make all there power in the low and mid-range, so for around town and "street light drags" you are the king! The top end is where it suffers. For a street bike this is fine, you rarely exceed the 120 + that gives the in-lines the advantage. The RC51 is a different ride all together. It has a much greater rev range, and fuel injection that makes it alot more superior to most twins.
My experience has been that twins "feel" like they turn in quicker, and you can definitely get on the gas sooner. They aren't for everyone, but if you like that, snap your head back torque feel, a twin can't be beat!
