SW-MOTECH Handlebar Risers
Thumbs up for SW-MOTECH handlebar risers. They have been difficult to find but as of this writing, Twisted Throttle has them for about $75. Install was simple, and no cables or wiring needed to be re-routed. Sitting position is improved for multi-hundred-mile days. I noted a small increase in mirror image vibration but not enough to be distracting. The vibration is not increased through the grips that I could detect. These will not “wow” you, but if you are looking for an incremental improvement in the ergos, I recommend them.
