An engine modification package designed to increase the displacement of Evolution-era V-Twin motorcycle engines. It typically includes larger diameter cylinders and pistons, enabling the engine to draw in a greater air-fuel mixture, thus generating more power. For example, a stock 80 cubic inch engine could be upgraded to 96 or 100 cubic inches using this type of aftermarket product.
The implementation of this modification offers significant performance enhancements, providing increased torque and horsepower across the engine’s operating range. This results in improved acceleration and overall riding experience. Furthermore, these kits often utilize improved materials and designs compared to original equipment components, potentially enhancing engine durability and longevity. Historically, these upgrades have been popular among motorcycle enthusiasts seeking to personalize and optimize their machines’ performance.
