REDS 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%.



Also REDS 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. The WR5 comes with a brand new 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 new cooling head is 10% lighter than the previous 5 ports generation.
