Compared to the original seat| Mustang’s all new Tripper Fastback is better by design. The 17" wide front seat sits the driver about 1” lower than stock for maximum control of the bike while stopped. The driver is also positioned further back "into the bike” with a full 8” rise for all-day back support. The passenger seat is 14" wide and is contoured to take pressure off one's thighs. Both the driver and passenger can now both enjoy longer rides together.The Tripper Fastback seat is designed to work with or without the stock passenger backrest.
