Purchased 4 piece set, driver/passenger seats and backrests. Amazing difference from stock. I now feel like part of the bike instead being perched on top searching for a comfy position. You would think a softer seat would be more comfortable, but not the case. E.D. seat is firmer and waaay more comfortable for both my wife and I. The driver backrest has saved my back and allows me to enjoy longer, happier rides. I will never again cheap out and settle for what a stock seat provides. Before I buy another motorcycle I'll first make sure that Erdody Designs has a seat to fit it.
