From REDS Racing:
After the launch of REDS R7 Evoke V3.0 we are pleased to announce the release of the new R5T Team Edition V4.0 Tuned by M.Rossi.
The New REDS R5TTE V4.0 is the perfect synthesis of innovation and technology and excels in high bite conditions and tracks that require that little extra on the bottom end of the powerband.
The engine is loaded with new features for 2016. REDS has introduced new sealing on both engines to help keep dirt away from the redesigned internals. A new lightweight combustion chamber, lightweight crankcase, and redesigned crankshaft create a lower working center of gravity. REDS has also added a new GEN2 venturi for improved mileage and tunability.
The R5T Team Edition represents our highest performance 3.5 cc off-road engine. It boasts state-of-the-art technology to further improve fuel mileage, performance and reliability.
ADVANCED CARB SYSTEM
The revolutionary carb features a differently positioned top end needle, rather than pointing diagonally upwards, it is now horizontally positioned much lower down. HCX Horizontal carb main features: higher idle stability, more precise tuning, easier access to high speed needle, higher mid/top range power.
The new Revolutionary GEN2 venturi guarantees improved fuel mileage and higher torque. The innovative design improves carburetor fluid dynamics for a even better tuning stability.
ANTI-DIRT SEALING SYSTEM
The new 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.
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.
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.
The new Tuned crankshaft features an improved aerodynamic design in order 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.
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.
5 PORTS & BOOSTERS
The sleeve with 5 inlet ports and exhaust port with boosters guarantees high power at each RPM and low fuel consumption.
Our flat piston, made from a high strength aluminium bar, is a true masterpiece of engineering.
HIGH QUALITY BEARINGS
The new high sealing and high reliability made in Japan front ball bearing ensures high idle stability. The steel-ceramic hybrid Swiss Made rear bearing ensures longer life and low friction at high temperatures.
