I have the last Lowrider seat made by Ultimate for the Rune, we went to their warehouse and bought the last one they had. It is in like-new condition, the removable backrest is included. We paid $800 for the seat and backrest, asking $500 plus shipping. The Lowrider is the most comfortable seat you'll ever ride on the Rune. My husband sold his Rune, with the stock seat on it, so this one became available.
