REDS Buggy nitro engine 721 PRO-X Factory Team DLC Ceramic Break in

At the heart of the engine is Mario Rossi’s specially hand-tuned crankshaft and sleeve package, designed to deliver exceptional power while maintaining outstanding fuel efficiency. The updated RTX rotating backplate reduces friction, improves idle stability, and increases overall engine efficiency. The newly designed cooling head lowers the center of gravity, improves aerodynamics, and provides superior cooling during long finals and demanding race conditions.

The Factory Team version features premium DLC-coated components and ceramic bearings for maximum durability and ultra-consistent performance under extreme racing conditions. This Pre Break-In version is professionally broken in by Mario Rossi, ensuring optimal performance right from the first tanks of fuel.

The 721 PRO-X Factory Team™ combines brutal top-end power, smooth linear throttle response, and excellent drivability — exactly what professional racers demand.
