Types of 125cc Quad Engines

Semi-automatic engines are designed for ease of use, making them ideal for beginners. With a 3-speed transmission and reverse capability, they allow riders to focus on handling rather than shifting gears. This is a great feature for those who are just starting out, as it helps them gain confidence without the added complexity of manual shifting.
3. Fully Automatic Engines
Fully automatic engines take convenience a step further, allowing the rider to simply accelerate without worrying about gear changes. These engines are perfect for casual riders who want a straightforward experience without the need for manual intervention.
4. Manual Engines
For those looking for an adrenaline rush, manual engines provide a more interactive riding experience. Riders must shift gears themselves, giving them greater control over the vehicle. This type of engine is more suited for experienced riders or those interested in competitive racing.
