• Enhance throttle response: The lightweight design reduces rotational inertia, making throttle feedback more sensitive and control readily available.
• Good heat dissipation performance: The structural design is conducive to oil splash lubrication and heat dissipation, preventing deformation or seizure caused by local overheating.
• Enhanced low-end torque output: Optimized weight distribution design significantly improves torque performance in the low-speed range, making starts and acceleration more powerful
• Reduce mechanical noise: High-precision machined mating surfaces reduce friction noise between components, making the engine run more quietly.
• Improve shifting smoothness: Stable rotational inertia helps the transmission engage, making the shifting process smoother and reducing jerks.
