Description

The ZS550SR is a cutting-edge engine designed for superior performance and efficiency. Featuring a unique cooling water channel, it enhances the cooling of the cylinder head, resulting in a higher heat dissipation rate and reduced intake pipe temperature. The engine is equipped with an odd-shaped combustion chamber utilizing eight-valve and two-cylinder technology, which optimizes fuel consumption and improves combustion intensity, thus saving energy and protecting the environment.

With a double overhead cam rocker-free mechanism, the ZS550SR minimizes mechanical losses by allowing the cam to drive the valve directly, ensuring reliable and efficient intake and exhaust processes. The lightweight piston design reduces inertia and wear, enhancing both power output and engine longevity.

Additionally, the special spray hole design effectively controls piston temperature, improving the engine’s operational environment and extending its service life. A high precision DID toothed chain reduces running noise while enhancing durability. Finally, the built-in balance shaft device balances engine vibrations, achieving stable operation with minimal noise.
