2003 Triumph SpeedmasterAcceleration & cruise controlCrash

2003 Triumph SpeedmasterAcceleration & cruise controlCrash

2003 Triumph speedmaster weak shocks on the front nose dive and travel over 8 inches with the powerful dual front brakes. The drag bars on the front put the rider up over the gas tank. When hitting the powerful brakes it puts the rider in the position of being on a downwards slope and if he weighs over 200 pounds gravity pushes the driver forward over the handllbars as he's traveling downhill based on the geometry of the bike.I went over the handlebars and broke two ribs at a 2mph emergency stop.Also, the bike has no kill switch and it keeps running and it damaged the left bearing on the engine.*Ak
