At what RPM should the Ninja 400 shift gears?

Generally, the shifting RPM for a car can be chosen between 1500-2500 rpm. Below is a related introduction to car RPM: Introduction to car RPM: Vehicle RPM refers to the rotational speed of the car's engine, which is the number of revolutions per unit time that an object moving in a circular path makes around the center of the circle. The function of car RPM: It promptly reflects the operating condition of the engine, allowing the driver to better coordinate with the transmission gear and throttle position, keeping the car in good working condition, reducing consumption, and extending the engine's lifespan. The RPM of the engine relates to the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different RPMs. The car's tachometer is located on the instrument panel, symmetrically placed with the speedometer.
I've been riding the Ninja400 for a while, usually shifting between 7000 and 8000 RPM, which allows the engine to run smoothly without losing power. When the bike was new, I tried shifting at lower revs around 4000 RPM, but it felt sluggish with poor power delivery. Now I'm used to shifting around 7500 RPM, especially during acceleration—it feels the most comfortable and avoids the jerkiness at peak torque. Don't shift too early, like below 5000 RPM, as the engine will lug; shifting too late, say above 10,000 RPM, will spike fuel consumption and risk overheating. For daily riding, adjust based on mood: city cruising can be done at slightly lower revs, around 7000 RPM, while highway riding feels more exciting at 8000 RPM. Maintenance is also important—change the oil regularly, and if you frequently shift at high RPM, the chain and clutch will wear faster, so check them often.
