Featuring a unique trapezoid stitch pattern on high-quality expanded vinyl, the solo allows the rider to sit comfortably back into a 15.5" wide bucket that provides superior lumbar support. The matching passenger seat offers a generous 11.5" width that is properly contoured for comfort. All seats and the matching sissy bar pad (76289) have been specifically engineered to provide truly uncompromising comfort for both drivers and passengers. Available with or without a built-in receiver that accepts a fully adjustable and easily removable driver backrest for maximum comfort. Note: Mustang's 11" passenger seat 76579 can be used with the 79683 solo, but the driver backrest cannot be used with the passenger seat installed.
