(1) High-standard integral cylinder head offers greater rigidity and precision, and effectively reduces abnormal noise.
(2) Adopts needle-roller double rocker arm design.
Imported valves for better heat resistance. Swirl intake ports inside the cylinder head boost intake efficiency by over 10%.
S40 features a larger casing than traditional 150 water-cooled models, fitting a bigger transmission system. The fully upgraded casing, with more scientific design in appearance and structure, greatly enhances power quietness and stability.
Double-sided toothed belt for more stable transmission and better heat dissipation.
S40 has larger drive/driven pulleys than traditional 150 water-cooled models, with more scientific transmission ratio. Aids steady power in shifting, cuts high-rev noise, boosts power climb; large transmission enhances engine performance.
