2. 3-VALVE, SHORT-STROKE ENGINE
SHORT-STROKE ENGINE
The 0.72 oversquare design reduces piston speed and mjnimizes friction. The bore is large enough to install three valves in one
combustion chamber. The power chamber adds extra torque at low and medium speeds. It
is located at the most ideal position
without sacrificing space between the engine and the ground due to reduced engine height. The exhaust gases from one
cylinder expand in the power chamber and have an extraction effect on the other cylinder.
