The perfect synthesis of innovation and technology. The M7 World Cup S is the State of the art of 3.5 cc 1/8 On-road racing class. REDS M7WCS 3.0 has been specifically updated to improve reliability and performance. The WCS represents our highest performance 3.5 cc on-road engine.
M7 WCS 3.0 Main Features: new crankshaft, new GEN2 venturi, new cooling system, made in Japan glow plug, lightweight back-plate design, flat piston, made in Japan front bearing, ceramic Swiss made rear ball bearing, RDC (Diamond) coating back-plate, XL extra long stroke, high bottom torque and power, high efficiency and low fuel consumption.
LIGHTWEIGHT & LOW GRAVITY CENTER
We designed the new REDS Factory Tuned line to be not only more powerful and reliable but lighter and with lower gravity center than ever before. To do that, we couldn’t just shave a millimeter here, a gram there. So we started from scratch, redesigning each essential part like crankcase, cooling head, combustion chamber and Black Diamond coated backplate.
ADVANCED CARB SYSTEM
The new Revolutionary GEN2 venturi guarantees improved fuel mileage and higher torque maintaining mid and top range power unchanged. The innovative design improves carburetor fluid dynamics for a even better tuning stability.
HANDMADE, TUNED AND ASSEMBLED
All parts are matched, measured by Mario Rossi within certain tolerances, hand built and Tuned by him personally. The engine leaves our factory with a hand inspection of all components and compression is checked.
NEW CRANKSHAFT - The new Tuned crankshaft features an improved aerodynamic design to increase horsepower and inertia to rotation. Crankshaft durability has been improved thanks to our special carbon steel and high technology coatings. It is also balanced with two high-density counterweights and our special silicone filling reduces the inertia to rotation.
DIAMOND BACKPLATE - The Diamond backplate is refined with a special anti-friction hard coating RDC. This coating allows decreased conrod-backplate friction improving engine efficiency and performance.
7 PORTS SLEEVE - The engine guarantees high power at high RPM and low fuel consumption thanks to the 7 ports ABC cylinder new timing. The M7 World Cup has been provided with flat and a special combustion chamber which allow to increase torque. Flat piston technology guarantees additional power at low and medium RPM preserving fuel consumption.
HIGH QUALITY BEARINGS - The new made in Japan 7x19x6mm front bearing is especially designed for high RPM. It features high precision, better sealing compared to metal shielded bearings, low friction and high reliability. Our Swiss Made ball bearing guarantee longer life at high temperatures. The steel-ceramic hybrid rear bearing ensures low friction for higher RPM.
