Types of 125cc ATV Engines
4-Stroke Engines
4-stroke engines are the most common type found in 125cc ATVs. They offer a balance of torque and efficiency, making them suitable for various terrains. Brands like Tao Motor and Coolster have made significant advancements in this area, ensuring riders experience smooth power delivery and reliability. The gas-powered, 4-stroke engines found in models from Superior Powersports are engineered to maximize performance while minimizing emissions.
Semi-Automatic Engines
These engines offer the benefit of manual shifting without the need for a clutch. This can be particularly appealing to younger riders or those new to ATVs. The ACE 125 ATV from GoKarts USA features a 3-speed semi-automatic transmission, combining ease of use with the thrill of manual control.
Electric Engines
With growing environmental concerns, electric 125cc ATVs are becoming increasingly popular. They offer a quieter ride and lower operating costs. While the power output may not match that of gas engines, models from Coolster provide sufficient performance for casual riding.
Performance Tuned Engines
For those who seek thrills, performance-tuned 125cc engines are available. These engines are designed for speed and agility, often lacking reverse functionality to keep the weight down. Brands like BDX Performance cater to this market, providing high-performance components that enhance speed and handling.
Key Features of 125cc ATV Engines
Transmission Options
One of the most significant features to consider when purchasing a 125cc ATV is the type of transmission. Fully automatic transmissions are user-friendly, allowing new riders to focus on handling. In contrast, semi-automatic options give more control, ideal for experienced riders looking for a challenge.
Reverse Gear
Having a reverse gear can greatly enhance maneuverability. Many models, such as those from Tao Tao and Coolster, come equipped with reverse options, making it easier to navigate tight spaces or difficult terrain.
Fuel Efficiency
4-stroke engines are generally more fuel-efficient than their 2-stroke counterparts. Brands like VMC Chinese Parts emphasize the importance of fuel economy, with their engines designed to reduce consumption without sacrificing power.
Safety Features
Safety should always be a priority when choosing an ATV. Many models come with features such as remote control stop, speed limiters, and adjustable shocks to ensure a safe riding experience.
