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.
MID-HIGH GRIP TRACKS
EXTREME TOP SPEED
" The WR7 is an amazing engine, the bottom end feeling along with top end speed make it stand out against the competition. The new cooling head helps with cooling and weight but looks fantastic. For me the WR7 has amazing drivability and will suit anyone that uses it."
A DIAMOND IS FOREVER
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%.
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.
HIGH POWER 7 PORTS
The sleeve with 7 inlet ports a single port exhaust guarantees low fuel consumption and smooth power delivery Our flat piston, made from a high strength aluminium bar, is a true masterpiece of engineering.
ADVANCED CARB SYSTEM
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.
