An engine modification package designed primarily for specific models of Harley-Davidson motorcycles, this upgrade centers around increasing the engine’s displacement to 107 cubic inches and often involves enhancing the camshafts for improved performance. Such a setup typically includes larger cylinders, pistons, and potentially modified cylinder heads to accommodate the increased volume and optimize airflow. For example, a rider seeking more power and torque from their motorcycle might install this assembly to achieve greater acceleration and overall responsiveness.
The significance of this particular enhancement lies in its ability to deliver a substantial increase in power and torque, particularly in the low to mid-range RPMs. This results in improved acceleration, easier passing maneuvers, and a more enjoyable riding experience, especially for heavier bikes or when carrying a passenger. Historically, similar modifications have been popular among motorcycle enthusiasts seeking to personalize and optimize their machines beyond factory specifications, demonstrating a long-standing desire for enhanced performance.
