My first bike is a CBR600RR, have been very happy with it but it is a matter of personal preference. I would have to agree with NinjaNick, though, take the MSF course and keep it at 600cc tops. Oh, yeh
Last couple of days have been great. Unfortunatly my bike is still out of service while I get some powdercoating done. Hopefully I will have it put back together this weekend.
