I worked with a guy who's new off the showroom floor soft tail had less horsepower than my 20 year old riding mower. It was about as fast as the mower until it got to a hill and the mower could pull away with ease. After a weekend cruise over the mountains he came home discouraged. Same story, his BMW buddy was riding in comfort and style at speed and he was getting his nuts shaken loose to go 63 mph.
It took a trip to a Harley tuner and another wad of cash to make it anything but a loud, vibrating turd. The Harley dealer could have cared less.
