Reds Racing 721 Pista on-road engine
Reds Racing have introduced their new super powerful 7 port on-road engine called the 721 Pista. The new 721 Pista engine features extreme power, high reliability and tuning stability. Combined with specific technical changes in the porting and new materials, this 7 ports engine features higher power and better fuel efficiency compared to any other engine. The new engine comes with a DLC Coated crankshaft and backplate for improved engine durability. The crankshaft can last approximately 3 times more than a standard crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is lengthened about 50%.
