Hi this is a large size saddle bag 19" across top 13" high lower pipes is must. each bag is 18 pounds approx. We have had customer put this bag on softail heritage. Brackets we carry and use easy brackets other brackets are out there and it is important that the bracket is chosen before ordering. Frame brackets are available I have seen them for $50 up to $300 the important thing is they support the bag away from caliper and axle bolt. Most of the time customers have had a bracket so it is where to start. Template is available to put up against M/C to see how big it would be. Allow 4 to 8 week delivery
