As engine rpm increases, a valve on the intake manifold opens, letting air enter directly
into the combustion chamber through the short, straight intake pipe. is allows a greater volume of air into the chamber, increasing the engine’s ability to breathe at high rpm, thus improving

Forged Pistons
e upper portion of each piston used in the DF250SS is treated with an alumite coating that increases heat resistance. A resin coating applied to the piston skirt improves resistance to wear and reduces friction.

Fuel Cooler
e cooler the fuel the denser it is, and the denser it is, the more performance it delivers. e DF250SS incorporates a water - cooled fuel rail in the fuel delivery system. e fuel is cooled before it is injected into the cylinder resulting in better combustion and better performance.
