2000 Big Dog Motorcycles PRO SPORT, white w/ teal scallops - The best handling Big Dog in the pound, the ProSport boasts a low stance rubber-mount frame that sports an all-new single-tube swingarm. We added a sculpted one-piece steel fuel tank and all new machined wheels with matching rotors and pulley. Now with 18 inch wheels front and rear, a 180 rear tire, and inverted front forks, the Prosport looks as good as it handles. The TP 107 cubic inch motor and 6-speed transmission pour on the ultimate power, but all in a low vibration package. Performance at its finest - the Big Dog ProSport.
