Instead of torque-drenched aggression, the impression is of restrained civility in equal measure to the impressive torque. Roll open the throttle at just about any engine speed, and the T-Bird surges forward with a steady, if joyless, resolve. And while engine vibration is held in check by twin counterbalancers, the package lacks both the Guzzi’s thud-pause-thud sense of low-rpm torque and the surprising high-rpm smoothness of the counterbalanced Harley. Indeed, with the revs elevated, the Triumph’s twin produces a bit of high-frequency sizzle. Fortunately, it’s geared tall enough that you’ll probably never have to experience this sensation, and given the drop-off in torque from the sub-3,000-rpm peak it makes little sense to rev the engine past, oh, 5,000 rpm. (Good luck figuring that out, since the T-Bird has no tach.) Probably because of the configuration, the T-Bird’s engine is a lugger that doesn’t feel like a lugger.
