This is the 2nd generation of the WR7 "DIAMOND EDITION" engine and includes the REDS Racing X-ONE 2143 One-Piece Off-Road Tuned Pipe which combines the REDS 2143 Pipe and the REDS XS Manifold to create this one-piece "Smooth" exhaust.

The pipe has been welded to the manifold to improve performance and fuel consumption. With X-ONE configuration there is no need for springs or gaskets, and the one piece design creates increased reliability and improved tuning stability.

The REDS Racing WR7 Diamond Edition 2.0 .21 Off-Road Competition Nitro Buggy Engine is a 7 port engine with special porting for extreme power. Based on WR7 Diamond edition, the engine comes with the same sleeve and piston, DLC crankshaft, crankcase, etc. to keep its power characteristics unchanged. But the carburetor and cooling system have been improved to provide more stability and improved consistency.

REDS improved the previous WR7 Diamond Edition with:  

  • Improved idle stability and tuning options thanks to a redesigned 3 needle carburetor.
  • Improved mid to top range power curve and feeling thanks to a special low speed needle and mid range spray bar.
  • improved cooling system specifically developed to widen the operating range so that the engine can work well in extremely hot conditions.
  • Redesigned cooling system guarantee a more consistent tuning in every track condition.
The 2.0 includes all the regular features included in the DIAMOND EDITION engine with a DLC Coated crankshaft and backplate for improved engine durability.

The crankshaft can last approximately 3 times longer than a standard crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is lengthened about 50%.

Other features include:
  • LIGHTWEIGHT & LOW GRAVITY CENTER: The REDS Factory Tuned line was designed to be not only more powerful and reliable but lighter and with lower gravity center than ever before. To do that, REDS started from scratch, redesigning each essential part like crankcase, cooling head, combustion chamber and Black Diamond coated backplate.
  • HIGH POWER 7 PORTS: The sleeve with 7 inlet ports and exhaust port with boosters guarantees low fuel consumption and smooth power delivery. The flat piston, made from a high strength aluminium bar, is a true masterpiece of engineering.
  • HANDMADE, TUNED AND ASSEMBLED: The engine is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards. This is core to the values that makes REDS Engines different from any other engine brand on the market.
  • ANTI-DIRT SEALING SYSTEM: The cooling head anti-dirt sealing system keeps the engine clean in a critical area between the cooling head and crankcase. The redesigned crankcase provides easier maintenance and a cleaner engine for longer life.
