This is the hand built Reds Racing M7WCS .21 7-Port World Cup Series On-Road Engine. The M7 World Cup S is the “State of the art” 3.5cc 1/8 On-road Touring Racing class engine. The engine has been optimized and provided with the highest technology to guarantee the best performance and reliability.

Latest Technology
The M7 World Cup S has been provided with a redesigned domed piston and an improved combustion chamber which allow increased torque. The domed piston guarantees additional power at low and medium RPM preserving fuel consumption.

The WCS is one of the lightest engines in its category thanks to the redesigned lighter cooling head, combustion chamber and back-plate design.

Simply Powerful
Thanks to the updated timing of the 7 ports ABC cylinder, the engine provides high power at high RPM and low fuel consumption as well.

The Extra Long Stroke XL engine geometry gives exceptional power at low-medium RPM, for a greater acceleration. The latest generation crankshaft is balanced with two high density material weights. Silicone filling reduces the inertia to rotation. The back-plate is refined with a special anti-friction hard coating called RDC.

The engine comes with all Swiss Made ball bearings to provide longer life and low friction at high temperatures. The engine is designed to guarantee an optimal cooling of the sleeve thanks to an ultra-finned crankcase and a header with "Direct Cooling" technology.

Best Quality
REDS Racing engines can be defined as unique in their genre thanks to Mario Rossi's special tuning which makes the engine simply more powerful and the finest quality control that guarantees performance consistency and reliability.
