My bike was silent until winter once it got cold I think the tolerances opened up a little and it became a rattle trap when the rattles started I took every single thing I did to the bike off which was down even to the dc power port and ram clamp on cell phone holder the noises were 100 percent coming from the bars and controls nowhere else, even took it into the dealer and they agreed, however since nothing was actually broken nothing was covered by warranty. I do not have crash bars.
I drilled holes, you have to or the switches won't bolt on, it's not an option cutting off the pegs there is nothing left to stop them from rotating the throttle would spin in your hand you'd have to epoxy them on or something if you didn't drill holes.
These bars and risers 100 percent eliminated the noise and vibration imo this is the very first thing every VX owner should do it made it a new bike.
