REDS All-new WR7 DIAMOND EDITION is a 7 special porting extreme power engine based on the famous R7 Worlds Edition engine that dominated The Dirt Nitro Challenge 2017, the Silver State 2017 and several important competitions.  REDS Racing has created the WR7 DIAMOND engine following the philosophy of product innovation, high quality, high performance and reliability. Everything that makes the WR7 unique today is an extraordinary step forward.

We decided to improve the previous limited version of the R7 Worlds Edition and provide the all-new DIAMOND EDITION engine with a DLC Coated crankshaft and backplate for improved engine durability. The crankshaft can last approximately 3 times more than a coventional steel crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is lengthened about 50%.

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.

The sleeve with 7 inlet ports and exhaust port with boosters guarantees low fuel consumption and smooth power delivery Our flat piston, made from a high strength aluminium bar, is a true masterpiece of engineering.

The revolutionary carb features a differently positioned top end needle, rather than a conventional carburetor pointing diagonally upwards. The REDS HCX is horizontally positioned lower down making REDS the only company with this set-up: greater idle stability, more precise tuning, easier access to high speed needle, higher mid/top range power.

REDS Horizontal carburetor has been provided with a revolutionary off-set GEN 2 venturi to assure improved fuel mileage and higher torque. The REDS HCX carburetor provides more efficient fluid dynamics for an even greater tuning stability.

The new engine is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards. This is core to the values that makes the V4.0 different from any other engine brand on the market.

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.
