$1500 accessory credit or 2.99% financing for 48 monLess chrome, more power and more attitude. The Thunderbird Storm comes with a 1,700 cc engine and hard-edged style. Based on our original Thunderbird, the Storm keeps the pure Triumph twinned headlamps but adds a low, blacked out look that's mean and minimalist for massive street presence backed up by huge torque and confident handling. Still laid-back but underpinned by serious power and the best handling in the class. This is a cruiser with a dark side. If purchased before March 31, 2016 get $400 accessory credit.
