As a beginner rider, it is generally recommended to release the throttle completely when shifting to a higher gear on a motorcycle, even when using the clutch. Here's the typical process for shifting to a higher gear:
Roll off the throttle: Before pulling in the clutch lever, gradually roll off the throttle by reducing the amount of throttle you are applying. This allows the engine speed to decrease, making the shift smoother.
Pull in the clutch lever: With the throttle closed or partially closed, pull in the clutch lever fully. This disengages the engine from the transmission, allowing you to shift gears without causing excessive strain or damage.
Shift up: While keeping the clutch lever pulled in, use your foot to shift up to the higher gear. Apply smooth and deliberate pressure to move the shift lever upward. Make sure the gear engages fully before releasing the clutch lever.
Gradually release the clutch lever: Once you have shifted into the higher gear, gradually release the clutch lever while simultaneously rolling back on the throttle. This allows the engine and transmission to smoothly re-engage, and the motorcycle to accelerate in the new gear.
Remember to always shift gears at appropriate speeds and RPM ranges for your motorcycle. Practice smooth and deliberate clutch control and throttle coordination to ensure smooth gear shifts and maintain control of the bike. It's recommended to consult your Honda CB Shine's owner's manual for specific shifting techniques and guidelines provided by the manufacturer.
As you gain more experience and become familiar with your motorcycle, you'll develop a sense of when to adjust the throttle while shifting gears based on the specific riding conditions and desired performance.
