Kicking a 1700cc Single

This great short video shows a truly unique and fascinating motorcycle, the Hackel-Wright chopper. This motorcycle is built around a single cylinder from a Wright R975-46, a 16,000cc 9-cylinder radial helicopter engine. This engine type is a variant of the Whirlwind radials which have been historically significant, powering a range of machinery from the Ford Trimotor aircraft to the Sherman tank.

Al Hackel's creation of a 1700cc chopper using a part of such a historically rich engine is not just an engineering feat but also a creative homage to the evolution of mechanical engineering. The concept of using a helicopter engine cylinder for a motorcycle showcases innovative reuse of aerospace technology in custom vehicle design, making it a standout in both mechanical ingenuity and historical significance. This kind of project not only draws attention for its sheer power and size but also for its unique story and the mechanical challenges involved in adapting such an engine for motorcycle use.The Wright R975 is historically known as a 9-cylinder radial engine primarily used in aircraft and military tanks during and post-World War II. Each cylinder of the original engine is roughly 1894cc, which means that the cylinder used in this motorcycle is one of these large, individually significant components.

Integrating an aircraft engine cylinder into a motorcycle involves considerable custom engineering. This includes crafting a unique frame, designing a compatible transmission, and configuring the fuel and exhaust systems to handle the different dynamics of a motorcycle. Given its size and origin, the engine produces a significant amount of torque at low speeds, making it very powerful but also challenging to handle. The sound of the Hackel-Wright chopper would be distinctive and much louder than typical motorcycles. Radial engines are known for their deep, throaty roar, and a single cylinder from such an engine would retain a robust, resonant sound. Expect a pulsating rumble that reflects the large displacement and the engine's aviation heritage.

At any event, such a motorcycle would be a major attraction, not just for its appearance and sound, but for the sheer novelty of its construction. This motorcycle is a statement piece that combines historical engineering with modern mechanical artistry. It serves as a testament to the creativity and skills of its builder, Al Hackel, and is sure to be a conversation starter wherever it goes, not just for its looks but for the unique auditory experience it offers!
