BMW Boxer Engine Models


BMW has a long and storied history of producing high-quality motorcycles. One of the key features that have made BMW motorcycles so iconic is their Boxer engine. The Boxer engine, which is also known as a flat-twin engine, is a type of engine design where the cylinders are arranged in a horizontally opposed configuration, with the pistons moving in opposite directions. This design offers several advantages, including a low center of gravity, excellent balance, and good handling. In this article, we will explore the various Boxer engine models used by BMW over the years.
