No, not all motorcycles have a quick shifter. A quick shifter is a feature that allows the rider to shift gears without using the clutch or closing the throttle. It enables seamless upshifts by momentarily cutting the ignition or fuel supply to the engine during the gear change.
Quick shifters were initially found primarily on high-performance sport bikes and some racing motorcycles, but they have become more common on a wider range of motorcycles in recent years. However, their availability can vary depending on the make, model, and trim level of the motorcycle.
Typically, quick shifters are more commonly found on sport bikes, super sport bikes, and some sport touring motorcycles. They are often included as standard equipment or as an optional feature on higher-end or more performance-oriented motorcycles. However, they are not universally present on all motorcycles, especially on smaller displacement or more budget-friendly models.
If you are specifically interested in a motorcycle with a quick shifter, it's advisable to check the specifications or consult with the manufacturer or dealer to determine if the particular model you are considering includes this feature.
