Нужный ли тюнинг? Ставим ЦПГ в сборе OTOM Big Bore на ZS 172 FMM (поршень 74 мм).

Hello, dear subscribers, fans of all kinds of motorcycles, channel guests, and haters! There's no limit to perfection—so goes the saying! Today, we'll test this assertion, attempting to improve the performance of the 2022 Regulmoto ZR 250 motorcycle, and see if it reaches that limit! You've probably already guessed it—our video is about tuning the ZS172 FMM-3A engine! All fans of Chinese motorcycles are familiar with this engine and its performance. It's a proper 250, producing 21 horsepower, but you always want something more, so we're installing a larger piston with a 74 mm piston from OTOM. Who's interested? How is it done? What was the result? Did the engine run smoothly with the new piston? Watch the video to the end and you'll find out! 0:00 Greetings! 0:10 Where are we going to install the Big Bore?
