2015 Triumph Thunderbird Storm ABS, SAVE BIG $$$$ ON A 2014 - Less 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 headlights but adds a low, blacked out look thats mean and minimalist for massive street presence backed up by huge torque and confident handling. We squeezed 102 cc more from the muscle-bound parallel-twin engine so that it packs an even bigger punch. Still laid-back but underpinned by serious power and the best handling in the class. This is a cruiser with a dark side.
