Rider comfort is a major factor, particularly for those who spend long hours on their bikes every day, and vibration is a prime factor. Over the years, the Yamaha FZS series has progressed and each time promises to bring improvements in the engine refinement and vibration control. There is no small amount of interest in how well Yamaha has addressed this issue with the FZS V4 Deluxe. Riders are comparing their experiences, talking about at what speeds the vibration become noticeable, how it affects longer rides, and whether the vibration levels are acceptable for a bike in this segment. Others are questioning if the vibration characteristics help make the FZS V4 Deluxe more 'connected' to the road or if they take away from it. It is the subject of comparisons with other popular bikes in the 150-160cc category and if Yamaha has been able to find the right balance between performance and comfort.
