Super Handling Power
The BF20 is the only engine in its class equipped with a power tilt and gas assist tilt variation, perfect for effortless engine tilt-operations and shallow water running. Cruising is improved and more comfortable with Honda’s unique pendulum-motion mounting system. This system is especially designed to eliminate vibration and maximise user comfort, allowing you to travel along the water with ease.

Reliability in a Compact Design
In addition to being incredibly lightweight, all BF20 models deliver both ease of maintenance and transport. With a long-stroke design and class-leading 350cc displacement, this engine is a top performer, providing optimum torque throughout the entire RPM range. A foldaway carrying handle positioned at the exact top/bottom balance point enhances portability and makes it easy to carry the engine in a level position.
