On the other hand, the Harley-Davidson Street Glide is a touring motorcycle powered by Harley-Davidson's Milwaukee-Eight engine. The Milwaukee-Eight engines come in different displacements, ranging from 107 cubic inches (1753cc) to 117 cubic inches (1923cc) in the larger models. While these engines offer good low-end torque and smooth power delivery, their power output is generally lower compared to high-performance sportbikes like the Yamaha R1. The specific power output of the Street Glide will depend on the engine displacement and any performance modifications.
It's worth noting that power is just one aspect of a motorcycle's performance, and different motorcycles are designed for different purposes. The Yamaha R1 excels in high-speed performance and cornering capabilities, while the Harley-Davidson Street Glide is designed for comfortable long-distance cruising with features like a large fairing, storage compartments, and a relaxed riding position.
