RD-ENBU0027 REDS 521 SPORT .21 5 Port Buggy Engine

REDS Racing all-new 521 Sport off-road engine. This engine belongs to Reds S LINE together with 721 Scuderia, Superveloce and Corsa, a new range of engines produced with different materials, from different suppliers and with new technologies. All assembled in-house and 100% made in Italy.

The new engine features high reliability, tuning stability and fuel mileage. Combined with specific technical changes in the porting and new materials, this 5 port engine features good power and fuel efficiency. 521 Sport guarantees excellent performance at a reasonable price. 521 Sport engine has been provided with the same aluminum carburetor as 721 engines to guarantee reliability and tuning stability.

REDS Racing 521 Sport features a new and unique high stiffness crankcase design. It is all new materials and casting technology. The engine is produced with pressure die casting, this is a very high quality process. Previous generation R line crankcase was with gravity casting.

Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario Rossi to achieve the highest quality standards.
