Coming from a GSXR750, my first impression was COMFORT! The busa is truly the perfect all around sportsbike. I loved the clock, fuel gauge, huge cushy seat, and how well it fit me (I'm 6'4", 260lbs). The bike has just unbelievable torque and power, I love how easily it pulls my wife and I when we ride. I used to stall my 750 sometimes when she was with me. On the busa, its like I can take off without even giving it throttle, it doesnt even know we are sitting on her!
The comfort factor is what really sold me. My wife loves the bar around the rear seat, and how much bigger and softer this seat is compared to the gixxer. The bike also doesnt vibrate like the gixxer, it's as smooth as a hard boiled egg! It's just the perfect bike, it's fast, comfortable, looks awesome, and handles great too!
As opposed to the ZX-12, with the pizza box for a ram air scoop under the headlights, yeesh!
