For better engine maintenance and fuel efficiency, it is generally recommended to shift gears in a way that keeps the engine operating within its optimal power band. The optimal shift points can vary depending on factors such as riding conditions, load, and personal preference, but here are some general guidelines for shifting gears on a Suzuki Gixxer 155cc 2017 model:
- Start in first gear and accelerate smoothly.
- Shift from first to second gear at around 10-15 km/h (6-9 mph).
- Shift from second to third gear at around 20-25 km/h (12-15 mph).
- Shift from third to fourth gear at around 30-40 km/h (18-25 mph).
- Shift from fourth to fifth gear at around 45-55 km/h (28-34 mph).
These are approximate speeds, and you should adjust them based on your specific riding conditions and the feel of the motorcycle. It's important to listen to the engine sound and feel the throttle response to determine the right time to shift gears.
Additionally, it's a good practice to avoid lugging the engine by shifting to higher gears at too low speeds or revving the engine excessively in lower gears. This can strain the engine and reduce fuel efficiency. Finding the right balance between engine RPM and gear selection will help you achieve better engine maintenance and good mileage.
