Garmin doesn't offer a motorcycle mount for this GPS line.  We received a few inquiries and now offer, from RAM Mounts, the handlebar option.  This mount comes with everything needed to mount your GPS.  No modification to your GPS is needed to use this heavy duty metal mount. Fits handlebar diameters up to 1.25 inches.  This mount includes the RAM-B-149Z metal handlebar mount with RAM-HOL-GA48U custom cradle.
