Less chrome, more power and more attitude. The Thunderbird Storm comes with a 1700cc 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 that's mean and minimalist for massive street presence backed up by huge torque and confident handling. We squeezed 102cc 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.
