I've been riding more than 18 months on the 250, and I'm so keen to upgrade. Picking a bike is my problem. I just want to see what people have to say. I always start looking around at the Kawa Z750 & Z1000, the FZ-1 & 6N's and the CB600F. But it never takes long for my eyes to stray over to the supersports, CBR, ZXR, YZR, GSXR, even the 675 get some attention, but is it really worth it? I commute to work everyday, only about 8-9kms, I ride glorious for breaky most saturdays, and do the odd 300km+ trip. I don't really see myself hitting the track but the supersport appeal is huge. I know as soon as I upgrade I will love my new bike, But what bugs you after owning a big bike, is there any advice you can give to sway me one way or the other.
