The new MC3X from RC Concept is a very high-end 3 ports engine. Powerful and smooth, it has been developed by RC Concept based on the successful MC3R. Since its launch the MC3R has attracted a large number of drivers by its ease of adjustment, power and price.

RC Concept has developed the MC3X in compliance with the standards of quality, innovation, performance and reliability that have made its reputation. All engines are build on by on and double checked before shipping.

The MC3X 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.


3 ports Sleeve

The MC3X’s sleeve has 3 transfers optimized for linear power while limiting fuel consumption.
