The new MC5X from RC Concept is a very high-end 5 ports engine. Extremely powerful, it has been developed by RC Concept based on the successful MC5R which has dominated the 2016 french Nationals with Reno Savoya.

RC Concept has developed the MC5X in compliance with the standards of quality, innovation, performance and reliability that have made its reputation.

This engine is used by our Worldwide Team.

The MC5X features our new DLC Coated crankshaft (Diamond-like Carbon) and our new carburetor with double bottom-end adjustment.

DLC Crankshaft – Diamond-Like Coated

The DLC treatment applied to the crankshafts of the X-LINE RC Concept is 4 times harder than a conventional treatment. It allows to multiply by 3 the crankshaft lifetime and to multiply by 2 the lifetime of the connecting rod.
In addition, idling returns are improved and top speed also.

Carburetor X-LINE RC Concept

The X-LINE carburetor has been developed to improve power, precision settings and return to idling. It has a double bottom-end adjustement.

5 ports Sleeve

The MC5X’s sleeve has 5 transfers optimized for incredible power while limiting fuel consumption.
