Each carburetor is equipped with a special sealing ring, enhancing both sealing and tuning stability.  The 721 Scuderia Pro Gen 4 is a high-torque engine crafted to significantly reduce fuel consumption. Its features include a long-stroke geometry of 16.2×16.9 mm, 7 scavenger ports, and a single exhaust port cylinder sleeve that collaborates with the crankcase, delivering enhanced low-to-middle-range torque.  The 721 Scuderia PRO is hand tuned undergoing meticulous hand-tuning by M. Rossi, including a silicone-filled, balanced, and tuned crankshaft.  Each engine is individually inspected and compression checked by Mario and Marco Rossi.  Other features include a double seal front bearing engineered for heightened durability and idle stability and Reds 9 balls rear ceramic bearing which enhances overall performance.
