So far, so good! I am very pleased with my decision to go with the FZ1. It has plenty of low speed, low rpm grunt and is very responsive in every gear. I haven't even ventured up in the high rpm range yet. I put some new grips on yesterday (ProGrip Gel). What a difference! I kept having the sensation that my hands were slipping off the stock grips. Since I'm used to my MX grips, I wanted something with some more bite. These also took away some of the vibration. The look pretty cool too!
