Reds Racing All-New WR7 2.0
REDS Racing is pleased to release their brand-new WR7 Diamond 2.0 engine. The new engine is a 7 special porting extreme power engine based on WR7 Diamond edition. The engine comes with the same sleeve and piston, crankshaft, crankase, etc. as the first generation of WR7 in order to keep its power characteristics unchanged.
We decided to improve the previous version with: - Improved idle stability and tuning options thanks to a new 3 needles setting 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. Furthermore, the newcooling system has been created to guarantee a more consistent tuning in every track condition.
The engine is available with DLC coated crankshaft or with steel crankshaft. We advise the following set-up to obtain better performance: 2143 X-One Smooth pipe, 7 or 8 mm venturi, Reds Racing Tetra Clutch System and TS3 or T5C glow plug
