REDS Racing releases the new WR5 Black DIAMOND™ LTD engine.
The Limited Edition WR5 BLACK DIAMOND™ engine is a 5 PORT with special features based on the famous R5T Team Edition engine that has been a staple in the REDS lineup for 6 years.

BLACK DIAMOND™

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

HCX™ CARB UPGRADE

We provided the WR5 with an improved HCX™ Carburetor featuring a new Flow Improved Low Speed Needle and new 7075 Aluminum Fuel Intake for improved tuning stability in extreme temperatures.
