How many kilometers does the UY125 take to complete the break-in period?

The break-in period is typically within 1500~3000 kilometers, with the first 300 kilometers being the most critical. The speed should not exceed 40 km/h, kept below 60 km/h before 800 kilometers, and below 80 km/h between 1000 to 1500 kilometers. Break-in period: Change the engine oil at 300, 800, and 1500 kilometers. After that, if using mineral oil, change it every 1000 kilometers, or every 1500~2000 kilometers if using full synthetic oil. During the break-in period, all gears need to be broken in, but avoid running at high RPMs in low gears. Vehicle speed: Vehicle speed refers to the distance a vehicle travels per unit of time, commonly measured in kilometers per hour or meters per second. Vehicle speed is one of the three parameters describing traffic flow and holds significant importance in traffic flow theory research.
After purchasing a new UY125, the break-in period typically ends around 300 to 500 kilometers, but always refer to the manufacturer's manual for specifics—though most riders recommend staying within this range. Having ridden similar models, I know that engine components need time to settle during the initial phase. Aggressive high-speed cruising or hard acceleration right away can lead to premature piston ring wear and shorten the engine's lifespan. During break-in, keep speeds below 60 km/h, avoid prolonged continuous riding, and regularly check the oil level and color, as new engines shed fine metal particles. After the first oil change, the engine felt noticeably smoother, and fuel consumption stabilized. In short, patience pays off—doing this right extends the bike's longevity and avoids costly repairs down the road.
