What engines does the scooter have? thank you

Technically, the most advanced pedal is Honda's PCX engine, which has the function of stopping the fire for 3 seconds and automatically starting the fuel filler door. In terms of power, PCX 150 is 15.5P, followed by Yamaha's NPA engine, and the first shot of the NPA engine is the 4CW engine carried by Yamaha Ling Ying, which is known as the machine god who can't ride badly! Old Ling Ying has been 18 years now, and no one has broken the 4CW engine. Later, 5HM Fast Eagle Engine and LY 149(JNG and Fuxi Engine) were all part of NPA series. KDU engine down, but from the internal structure of the machine, KDU is actually very similar to GY6, but KDU mainly focuses on the market of 1 10 and 150. At the bottom of the list is the traditional GY6. The machine has a simple structure and a strong growth rate, but the transmission ratio is unevenly distributed. It requires a high speed when starting, and it has a strong mopping feeling when returning to the throttle (riding in the snow, the rear wheel of the throttle will slip when running! ) So Qi Zi said that 150 horsepower in the corner is amazing 14P, which is really ignorant. Yamaha S-MAX 155 HP 14.5P, Honda PCX 150 HP 15.5p ... Yang Guang, after all, is a technology stolen from Honda, which can only be imitated and followed, and can never be surpassed. Moreover, the curve of 14P has four valves, and Yamaha and Honda also have two valves. If it is a four-valve 150, the horsepower is generally around 20P (model 06 CBR 150 horsepower 23P).
