Triumph claims 93 hp at 5,400 rpm and 111 pound-feet of torque at just 3,550 rpm. Nothing about the way the bike moves refutes those claims; torque is omnipresent and controllable through well-tuned electronic fuel injection (no ride by wire here, though). What the Thunderbird isn’t, though, is aggressive in any way. The engine has a lot of flywheel, very soft throttle response, and tallish gearing, giving it a slightly groggy demeanor. This liquid-cooled engine revs languorously, and only offers a “traditional” big-twin thumpa-thumpa at very low revs. The T-Bird has six speeds between the engine and the belt final drive, but you could probably get by with three. It's a very pleasant experience, but it's not the usual American-style kind of chest pounding.
