The REDS WR5 HE Black Diamond .21 engine is a 5 port off road engine based on the famous R5T Team Edition engine that has been a staple in the REDS lineup for 6 years. The WR5 Black Diamond is available in two different models - the WR5 Black Diamond HE High Efficiency that offers low fuel consumption system and smooth power band for high driveability, and the standard WR5 Black Diamond that offers the REDS 5 port high torque power band.

Black Diamond
The REDS 5 port engine with a Black Diamond DLC Coated crankshaft has been improved. The DLC crankshaft can last approximately 3-4 times longer than a standard crankshaft thanks to the extreme hardness and low friction of the diamond coating. Even the conrod life is lengthened about 50%.

The WR5 includes an improved HCX Carburetor featuring a Flow Improved Low Speed Needle and 7075 Aluminum Fuel Intake for improved tuning stability in extreme temperatures.

Gloss Black
The WR5 comes with a Black Gloss Cooling Head which features an innovative design for improved air flow in order to increase the cooling and guarantee a low gravity center. The cooling head is 10% lighter than the previous 5 port cooling head.
