The legacy of cutting edge motorcycle design continues with the Big Dog ProSport. For true motorcycle excitement, nothing quite matches the ProSport when it comes to high-output performance in a package that s a dream to ride. If you re tired of excess vibration then get on a ProSport and feel the Big Dog difference. We cradled our super-smooth TP 107 cubic-inch engine in our revolutionary Daytec three-point rubber mount frame. This all-new frame, along with dampening engine vibration, was designed for lower seat height while still maintaining optimum ground clearance. To reduce highway vibration further we opted for Baker s super-premium 6-speed close ratio transmission. A quantum leap in highway performance, the Baker adds one more dimension to Big Dog s commitment to comfortable cruising.
