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 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
