I bought a Kawasaki ZX6 (600cc, 1984), I had this old bike for two (one and a half) seasons... in Canada that's 7 months riding. I want to get a new bike. Should I get the 900 cc or the 600 cc, I'm 6.0 and 210lbs. I was looking at the CBR's. My bike is really old so people tell me that I'll get a kick out of the new CBR F4i ... but: will I not want a 900 cc next year? Should I just get the 900 cc now??
I say stay with the 600's. You say you have been riding only 7 months. You are still a beginner.
Everyone is correct stating that the new 600's have a ton more power than the old ones.
But if you really want a 900 then you will not be happy until you get a 900.
The choice is yours. We can only advise you.
