Nothing at all.
The bike is well built, rides beautifully and is very comfortable.
The torque range in the 're-mapped' Fireblade' 919cc engine is perfect for this style of bike, allows easy commuting with few gear changes required, and great open road performance with smooth acceleration and plenty of power right through the rev range.
I haven't had this bike for long and it is still running in, but I am very, very happy with it, and would recommend it to any serious motorcylist who wants a beautifully built and comfortable bike for a great price. You get far, far more for your money with this bike than many other manufacturers give you.
The late 2004, 2005 series have a fully adjustable front suspension, something earlier models lacked, and that means you can set up the bike for most riders and riding conditions - that was the only deficiency with earlier models, now fixed.
I've had my 919, for little over a year and it is the ultimate ride. I ride this thing everyday it's not raining to work in Manhattan. All year I ride. Freeze the 20 minutes to work - it's okay.
I'm coming up on 8000 miles and nothing needs fixing. I change the oil and feed it gas, and it keeps going strong. In winter it starts right up.
I took the dual exhaust off and put a single hollow 4 inch barrel on, and it's the loudest street bike I've ever heard. The bike owns the road everyday in the city, zig zagging through traffic and on the highway screaming past those dragging 4 wheelers.
I love my bike because of its universal style that can appeal to anybody. It's a rare metallic green. No plastic, just metal hanging out with a big cruising headlight. Comes with the performance and speed of a race bike and the comfort and attitude of a cruiser.
Here in New York, the naked bike isn't that popular, but for me, it's all I could ever ask for from a motorcycle.
