. Crankshaft support frame: A new crankshaft support frame is added to enhance the strength of the crankshaft at high speed and improve operational stability.
. Integrated processing of the crankshaft: using a 90-degree time-sharing crankshaft structure, the operation is smoother and more sensitive, and the maximum speed can reach 13,500 rpm.
. Valve/camshaft upgrade: The valves are modulated and processed with a new process, which increases the service life by 3.5 times compared with the previous generation. The high-advance camshaft design makes the throttle response more sensitive.
. Double synchronous pulleys: The double synchronous pulley timing structure greatly reduces the risk of tooth skipping during high-speed operation.
. Carburetor/intake pipe upgrade: The carburetor is rematched with the oil needle, making the engine easier to start. The newly designed intake manifold is easier to operate.
. Oil pan upgrade: The oil pan size is enlarged to facilitate independent lubrication in later upgrades.
