Although this dyno chart shows a T111 engine, the performance is the same as the V111. Both engines have the same displacement, bore and stroke, cylinder heads, fuel system, and cam grind. Since this is a touring engine, low and midrange torque is the most important attribute. However, the horsepower of these engines is very respectable.
The new V111 motorcycle engine is designed for torque more than top end horsepower. The short 41/8" stroke is equal to the large 41/8" bore, which minimizes vibration. The relatively low lift S&S 585 cam and the single coil Sidewinder® valve springs minimize valve train noise. A smooth, quiet, torquey engine is ideal for touring applications where vibration and noise can get old on a long ride, and a loaded bagger pulling a trailer can overtax a stock engine.
