This exceptional engine boasts Reds Racing’s revolutionary 3 needle carburetor, only available on Gen 4 Scuderia engine. This carburetor not only facilitates superior tuning in diverse conditions but also ensures a more consistent and linear power delivery.
Each carburetor is equipped with a special sealing ring, enhancing both sealing and tuning stability.

Key Features:

1. Double Seal Front Bearing: Engineered for heightened durability and idle stability, the high protection double seal front bearing is a testament to the engine’s robust design.

2. REDS 9 Balls Rear Ceramic Bearing: Elevating durability and reliability, the rear ceramic bearing with 9 balls enhances overall performance.

3. Fuel-Efficient Design: The 721 Scuderia Pro Gen 4 is a high-torque engine meticulously 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. This design not only extends runtime but also positions the Scuderia as one of the fastest engines globally.

4. DLC Coated Crankshaft and Backplate: For unparalleled engine durability, the 721 Scuderia PRO comes equipped with a DLC-coated crankshaft and backplate. The diamond-like coating on the crankshaft increases its lifespan by approximately three times that of conventional steel crankshafts. Additionally, the conrod’s lifespan is extended by about 50%.
