My favorite passenger has been impatiently awaiting a backrest, so she was pleased when the Chieftain Quick-Release Backrest (indianmotorcycle.com; $625) was the first accessory to arrive. It's a pricey piece, but it's well engineered, easy to install, and makes the passenger happy. The kit includes the main backrest and a cushioned pad that matches the studded saddle. Installation took about 10 minutes. Simply remove the saddlebags using their quick-release fasteners, pull two screws on each side to remove the spool-type spacers that mount the bags, press a plastic flange over each spool, and reinstall the spools. Then the backrest slides over the front spools and drops down over the rear spools. Locking levers rotate down around the rear spools to secure the backrest. To remove the backrest, just lift the levers. If you want to make it harder to remove, the kit includes a couple screws to lock the levers in place.
