The oversized impeller is a component designed to increase the cooling capacity of the system.
The kit is made of black anodized 6082 aluminum with a special base that raises the lid, increasing the flow rate (hydrodynamically tested) of 52% of the coolant and improving heat exchange.
This modification makes it possible to stress the bike less (thermally) during hot periods without compromising anything during cold periods since the thermostatic valve is able to compensate for the cooling increase (simply remaining more closed ).
To increase the flow rate at the same engine speed, a simple increase in the surface of the impeller blades is used, obtained thanks to the insertion of a special spacer interposed between the engine base and the water pump covers.
The kit can be mounted on all LC8 engines :
- KTM 950/990 Adventure 2003- 2013
- KTM 950 Super Enduro 2006 – 2008
- KTM 950/ 990 Supermoto 2006 – 2013
