DO NOT ATTEMPT TO USE THIS SEAT IF:  
• You do not understand these installation and use instructions; 
• You do not understand any part of the seat’s mounting system; 
• You have any doubts as to the security of the seat’s mounting system. 
• If you have any concerns or questions, seek help at your qualified motorcycle dealer or call the Saddlemen support line at (310) 638-1222. 
Remember: Motorcycling can be a dangerous activity. Installation of any accessory can increase your risk if it is not installed properly. You are responsible to install this seat or any 

accessory so it will not contact any portion of the drive train, suspension or steering, or if it will in any way interfere with the operation of your motorcycle. 

 

These instructions apply only to H-D Softail Breakout models from 2013 to 2021, and 

Fat Boy models 2018-2021. 
1. Remove your bike's stock front seat by unscrewing two nuts located at the back of 

the seat. Pull the seat away from the gas tank, being careful to not scratch your fender. 

Your motorcycle will have two threaded studs coming up from the fender.  
2. Saddlemen includes a Y-bracket with every solo seat for Breakout and Fat Boy 

(2018+) models (Fig. A). Install this bracket onto the two threaded seat posts, using the 

original nuts. The Y-bracket includes a single threaded post that will sit over the fender, 

facing up. 
3. Your Saddlemen seat comes with a single rear mounting bracket installed in the 

Shipping Position (Fig. B). Using a 4mm Allen wrench, unscrew the two bolts, turn the 

mounting bracket around, and reinstall the two bolts with the bracket in the Installation 

Position. 10 -to- 15 ft/lbs torque is recommended, do not overtighten.
4. With the rear mounting bracket installed and ready, slide the front seat tab into the 

frame receiver under the bike's gas tank, and carefully set the rear seat bracket onto 

the threaded stud of the Y-bracket. A new flange nut is included, to secure your seat to 

the Y-bracket. Tighten to 10 -to- 15 ft/lbs.

For additional paint protection, use a Saddlemen Adhesive Fender Washer (PN: 8901) and a Saddlemen Protective Tape Kit (PN: 4320-0807) which 

further protects paint from abrasion damage from a seat, and is also useful when mounting other accessories such as tank bags or saddlebags. 

NOTE: It is not considered abnormal for your new Saddlemen seat to touch the motorcycle’s chassis in certain places (just like your original seat). 

Due to the natural variance of your vehicle and your new Saddlemen seat, you should always check to see if portions of the seat are touching painted 

or finished surfaces on your motorcycle. If the test fitting of your seat indicates an area where the seat is touching a sensitive surface, you can pro-

tect that area by using the Saddlemen Protective Tape Kit.    

It is your responsibility to make sure the seat installation does not create an unsafe or illegal situation. Remember that this seat is a custom acces-

sory. It is your responsibility to check the installation to determine if it will be safe for you to operate the motorcycle and to properly and safely carry 

a passenger (this includes reinstalling the passenger grab strap or installing a suitable replacement). You must also ensure that the installation does 

not damage your vehicle in any way. After 50 miles (80 kilometers), recheck the seat’s mounting to make sure it is still secure. Inspect all of your 

accessories and related hardware before and during each ride. An improperly mounted seat can interfere with the vehicle’s operation and cause an 

unsafe riding condition.
