Yes, motorcycles do have transmissions. Most motorcycles, especially those with larger engines, are equipped with manual transmissions similar to those found in cars. These transmissions typically have multiple gears that the rider can shift through using a foot-operated gear shift lever or a hand-operated gear shift lever on some models. By shifting gears, the rider can change the ratio between the engine's rotational speed (RPM) and the speed of the motorcycle, allowing for efficient power delivery and control over various riding conditions.
These automatic transmissions do not require manual shifting and typically use a continuously variable transmission (CVT) or a similar mechanism to vary the gear ratios automatically based on the engine's speed and load.
In summary, while motorcycles can have manual transmissions that require the rider to shift gears, there are also models with automatic transmissions that handle gear shifting automatically. The choice between manual and automatic transmissions often depends on the specific motorcycle model and the preferences of the rider.
