The REDS M7 WCS Diamond V1.1 .21 7-Port World Cup Series On-Road Engine is a 7 special porting extreme power 1/8 on-road engine based on REDS M7WCS 3.0 engine. REDS decided to improve the previous M7 WCS On-Road engine with a DLC coated crankshaft, a redesigned carburetor, a redesigned cooling head and REDS anti-dirt sealing system.
Main Features: DLC Coated crankshaft, redesigned carburetor, redesigned cooling head, REDS anti-dirt sealing system, GEN2 venturi, made in Japan glow plug, lightweight back-plate design, flat piston, made in Japan front bearing, ceramic Swiss made rear ball bearing, XL extra long stroke, high bottom torque and power, high efficiency and low fuel consumption.
LIGHTWEIGHT & LOW GRAVITY CENTER
We provided the M7 DIAMOND with a brand new cooling head which features an new design for improved air flow to increase the cooling and guarantee a low gravity center. The new cooling head is lighter than the standard ones. Furthermore, REDS cooling head anti-dirt sealing system keeps the engine clean in a critical area between the cooling head and crankcase. The redesigned crankcase provides easier maintenance and a cleaner engine for longer life
ADVANCED CARB SYSTEM
The REDS On Road carburetor has been redesigned to get greater idle stability, more precise tuning and improved power delivery. REDS 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 the factory with a hand inspection of all components and compression is checked.
DLC CRANKSHAFT - Horsepower
The Tuned crankshaft features an improved aerodynamic design to increase horsepower and inertia to rotation. Crankshaft durability has been improved thanks to the special DLC coating. The crankshaft can last approximately 3 times more than a standard crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is lengthened about 50%.
DIAMOND BACKPLATE- Plasma Assisted Technology
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 - Horsepower
The engine guarantees high power at high RPM and low fuel consumption thanks to the 7 ports ABC cylinder 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 - Low Friction
The 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. The Swiss Made rear ball bearing guarantee longer life at high temperatures. The steel-ceramic hybrid rear bearing ensures low friction for higher RPM.
