Before testing this best 400 sport ATV, I never realized how much worse rough terrains felt without proper traction and suspension.

After extensive testing, I recommend the MASSFX Rear Tire Set 4ply ATV Sport Quad Tires for reliable, lasting performance on all terrains.

How Can You Maintain Your 400 Sport ATV for Optimal Performance?
To maintain your 400 Sport ATV for optimal performance, consider the following key practices:
- Regular Oil Changes: Frequent oil changes are essential to keep your engine running smoothly and to prevent buildup of dirt and debris. It’s recommended to change the oil every 100-200 miles or as per the manufacturer’s guidelines, which ensures that the engine is well-lubricated and reduces the risk of overheating.
- Check Tire Pressure: Proper tire pressure is crucial for safety and performance. Low tire pressure can lead to poor handling and increased tire wear, while over-inflation can cause a harsh ride and reduced traction; checking tire pressure before each ride helps maintain optimal performance.
- Inspect and Clean Air Filter: A clean air filter is vital for optimal engine performance as it ensures that the engine receives the correct amount of air for combustion. Regularly inspect the air filter for dirt and debris, and clean or replace it as necessary to improve fuel efficiency and power output.
- Battery Maintenance: Keeping the battery in good condition is essential for reliable starting and overall performance. Regularly check the battery terminals for corrosion, ensure connections are tight, and consider using a battery maintainer if the ATV will not be used for an extended period.
- Lubricate Moving Parts: Regular lubrication of moving parts such as chains, axles, and suspension components reduces friction and wear, extending the lifespan of these parts. Use appropriate lubricants as per the manufacturer’s recommendations and perform this maintenance regularly, especially after riding in wet or muddy conditions.
- Inspect Brakes: Ensuring that your brakes are in good working condition is critical for safety. Regularly check the brake pads and fluid levels, and replace them if they show signs of wear or if the braking performance diminishes.
- Flush and Replace Fluids: Besides engine oil, other fluids such as coolant and brake fluid also require regular checks and replacements. Flushing these fluids at recommended intervals helps prevent overheating and ensures that the braking system functions properly.
- Keep It Clean: Regularly washing your ATV helps to remove dirt, mud, and debris that can cause rust and wear over time. A clean ATV not only looks better but also allows for easier inspection of components and can help identify potential issues early.
