Reds Racing 321 ESTREMO X Line Off-Road Engine

Italian engine tuner Reds Racing has collaberated with iconic Japanese engine manufacturer O.S. to bring offroad racers the new 321 ESTREMO X Line Off-Road Engine.  The new X Line debuts with the 321 ESTREMO, a 3-port engine designed to offer a different driving character compared to their well-known 721 S Line platform.  The 721 S Line will continue to be fully produced in Italy, maintaining the same philosophy, engineering approach, and performance characteristics that have defined it over the years.  The new 321 engine is manufactured in Japan and has been fully developed according to Reds Racing design, engineering, and testing specifications.  Final assembly and tuning are carried out directly by Mario Rossi and Marco Rossi, ensuring the performance standards and precision expected from Reds Racing engines.  The development of the new 321 ESTREMO represents an important collaboration between Reds Racing and one of the most respected companies in the RC engine industry, O.S. Engine.
