I was wondering if these bikes are comparable in any way. How many horsepower do they have?? I think they are both decent bikes to start on. My neighbor recently bought a katana for his first bike and says that its not too bad besides the fact that its a bit heavy when hes going slow. One of my buddies got an 03 ZZR this past spring. He says personally he thinks its a bit too fast but he was able to handle it OK. Both took the MSF course and then bought their bikes. Im taking into consideration for both bikes for starters. What yall think??
