First you'll need a ruler or measuring tape.

A. Take a side to side measurement: Measure side to side, from the back of the saddle, (riders position) to the arm of the directional signal, you'll need to compare this measurement with our length measurements of the desired saddlebag. This measurement should be greater than the bags length. (See image below for reference)

B. Take a top to bottom measurement. Measure from the bottom of the seat pad to the top of the exhaust pipe as a reference. This measurement must be at least 1" inch greater than the height of the desired saddlebags (see picture below for reference). Measurement of bag are given in the item description of the listing.

With these measurements, you will have the sizing needed for YOUR specific bike, and be able to make your purchase without frustrating fitment issues.
