The 111 cubic inch Thunder Stroke engine is simply a joy - to look at, to listen to, and especially when you twist the throttle. The power and torque of the locomotive-like engine is prodigious, and readily on tap. After my occasional roadside photo stops, I would sometimes forget to downshift, and pull away from the stop in third gear, but the engine never lugged, and by the time the clutch was engaged, I was approaching 20 mph and there was no need to downshift. In slow roll-ons and hard acceleration, as well as small changes to throttle position to adjust lines in curves, the throttle-by-wire system was smooth and predictable. On a ride through Deal’s Gap, keeping the Vintage in third gear for speeds from 20 to 40 mph through the continuous curves for the 11-mile stretch, I never needed to shift, and rarely used the brakes. On the Interstate, I locked the cruise control on 75 mph, and the engine sung its sweet tune at 2800 rpm, rock solid. In short, the engine never failed to deliver in every circumstance. While the engine does require 91 octane fuel, economy for my rides was surprisingly good.
