The new 721 Superveloce Pro-X is an evolution of the Limited Edition engine. It is a classic 3.5 cm3 7 ports engine.

This feature that has now become the benchmark for REDS Racing engines for the 1/8 buggy class.

It incorporates all the features that contributed to Top Qualifier result in the 2024 World Championship and in this year's European Championship, as well as another European Champion, making a total of 4 for their off-road campaign (showing the 4 stars on the cooling head)!

It can be used for 1/8th Buggy and Truggy. 

Thanks to “Extra Tuning” and each piston sleeve by Mario Rossi, the new engine has an extremely linear power distribution, making it super powerful but at the same time easy to drive. Our main objective was to develop a super-fast engine capable of guaranteeing good fuel mileage. 

It is equipped with an RTX rotating backplate that increases engine power and improves idle stability, thanks to a drastic reduction in friction between the connecting rod and the back plate. 

The VCX3-A carburetor features a 3-needle platform for easy adjustment in all conditions. What's more, thanks to its mid-range needle, this carburetor guarantees high power and linear distribution.

The insulation ring of the carburator has been upgraded with an ultra-resistant aerospace-grade polymer. This carburetor is equipped with a double screw joint for easy positioning and adaptation to any type of servo.
