Born to compete at the highest level


The REDS 321 Estremo Worlds Edition is a Limited Edition developed from the championship-winning 321 Estremo platform, winner of the 2026 EFRA 1/8 Off-Road European Championship with Juan Carlos Canas Carrasco.

Developed for the most demanding racing conditions, the Worlds Edition combines performance, thermal management, reliability, and consistency with exclusive components specifically designed for high-level competition.


WORLDS EDITION COOLING HEAD


The exclusive Worlds Edition Cooling Head has been developed to optimize engine temperature management, particularly in high ambient temperatures and during extended runs.

A more stable operating temperature helps maintain consistent carburetion and performance throughout the run, while improving overall engine reliability and repeatability.





2143 XONE WORLDS EDITION – OXD TREATMENT


The engine is paired with the special 2143 XONE Worlds Edition exhaust system, featuring the exclusive OXD surface treatment.

The OXD treatment provides increased resistance to wear, deterioration, and high operating temperatures, helping the exhaust maintain its characteristics over time.

In addition, the treatment contributes to improved exhaust gas temperature management, enhancing engine performance and the overall efficiency and consistency of the engine–exhaust system.
