721 Scuderia features new materials for piston, sleeve and crankcase in order to optimize thermal expansion and improve power. The engine is produced with pressure die casting, this is a very high quality process. Previous generation R line crankcase was with gravity casting. 721 Scuderia comes with a DLC Coated crankshaft and backplate for improved engine durability. The crankshaft can last approximately 3 times more than a conventional steel crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is improved by approx 50%. The new engine is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards. This is core to the values that makes Reds Racing engines different from any other brand on the market.
