Mustang Motorcycle Products has built seats in Terryville, Connecticut since 1980, and is the name most V-twin riders reach for when the stock seat has ended a ride early. Its wide touring and solo seats are built on steel baseplates with real foam density rather than cosmetic padding.
The Mustang Solo Diamond seat for 2018-2021 Harley-Davidson models combines a low-slung profile with rider-focused comfort. Its 12.5-inch wide driver bucket provides a relaxed cruising position without sacrificing ground reach. The synthetic glove-leather cover with detailed stitching ensures both durability and a premium look for your V-twin.

Excellent seat for shorter dudes
2022 Heritage Classic. I'm a shorter rider at 5'5" with a bad lower back. This seat is perfect as it sits me a bit lower and pushes me up where I can easily flat foot the bike when stopped and have pretty of lumbar support while riding. The fit and finish is great and the backrest flips down , making it easy to swing your leg over. For those complaining the backrest feels loose, tighten the slotted tensioner screw under the bucket, this locks the backrest into place.
