Yamaha FZ6 Modifications to Considermy series about the different modifications that are available for the Yamaha FZ6 motorcycle. It seems like every time I turn around I find something new that can be done to my FZ6. In Part 1 of this series I discussed the aftermarket possibilities of upgraded exhaust, windscreens, and seats. In Part 2 I will give an overview of the options available for new grips, levers, and rear sets. In contrast to a powertrain modification, these are mostly aesthetic and comfort rather than performance enhancements. Let's get to it.
