I bought this sr 50 new and had it shipped to High Gain Tuning (please look up their website) to have the owner, Richard Bruckner install the following: Mellosi 70cc kit, Vance ZXR pipe, variator, bigger reed block, and reprogram the ECU (electronic control module). I also have modified the fuel pump to fix the electrical issue that they are known to have. This sr 50 is immaculate. It runs perfect with no issues and only has 740 miles. The top speed is somewhere between 50-57 depending on conditions. This scooter has always been garaged and has never seen rain. Buyer is responsible for pickup or shipping costs. Please email me with any questions. Thanks.
