What is the recommended speed for a motorcycle during the break-in period?

During the break-in period, it is best to keep the motorcycle speed at around 40 km/h. Here are some additional details: 1. Frequent oil changes during the break-in period are beneficial for the engine. After the break-in, change the oil approximately every 1,500 km. 2. After a new motorcycle leaves the factory, the clearance between engine components is small, and the moving surfaces are rough. A break-in process is necessary to achieve the optimal fit between gears, pistons and cylinders, shafts and bearings, etc. The break-in period for a new motorcycle is 1,200 km, but for the engine to fully break in, it should be between 1,600-2,000 km. 3. The first oil change during the break-in period should be at 500 km, the second at 1,000 km, and thereafter every 2,000 or 3,000 km. It is strictly prohibited to use fully synthetic oil during the break-in period because the engine needs to wear in. If fully synthetic oil is used, its excellent anti-wear properties may result in the engine not being properly broken in even after reaching the required mileage.
After riding motorcycles for so many years, I've found that keeping the speed between 60 to 70 km/h during the break-in period is most appropriate. Exceeding 80 km/h can cause excessive friction between new engine components, leading to heat buildup and accelerated wear or even permanent damage. I've helped friends tune several bikes, and I remember one beginner who didn't follow this advice and frequently rode at 90 km/h on highways. After just a few hundred kilometers, the engine vibration noticeably increased. I recommend maintaining this speed range for the first 500 km, avoiding sudden acceleration or prolonged cruising. Gentle riding allows components like piston rings and bearings to seat better. Keep the RPM within 2500 to 3000. Regular oil changes are essential to remove metal particles generated during initial break-in. This approach ensures long-term reliability, better fuel efficiency, and helps develop cautious riding habits.
When I first got my new motorcycle, everything felt super fresh. I checked the manual and forums about the break-in speed, and the general recommendation was around 60 km/h. Going too fast puts a heavy load on the engine and can easily cause overheating. I tried riding at low speeds on suburban roads myself, and the engine sound was noticeably smoother. Try not to exceed 70 km/h, as new parts have rough surfaces, and high-speed friction might leave tiny scratches. For the first 300 km, be gentle—avoid sudden braking and heavy loads. I kept the RPM between 2000 and 2500. On the other hand, going too slow isn’t ideal either; speeds below 40 km/h might not fully break in the engine. I checked the oil color weekly to monitor wear. Treating the new bike gently not only extends engine life but also helped me focus more on riding details and safety.
From a maintenance perspective, it is recommended to keep the motorcycle's speed around 60 km/h during the break-in period. Exceeding 80 km/h may cause excessive friction between engine components, leading to increased temperatures and damage to surface treatments. Riding at slower speeds helps parts wear in evenly. Avoid sudden acceleration as abrupt heavy loads can create internal pressure. Maintain engine RPM in the lower range, such as below 3,000. After the break-in period, change the oil - the presence of impurities in the oil indicates the effectiveness of the break-in. Timely cleaning can enhance long-term performance.
