What to Consider Before You Buy

Before scrolling listings or heading to a dealer, answer these questions first. They will guide your purchase and reduce the risk of getting a machine that’s unsafe or unsuitable.

• Who will ride it? Consider the rider's age, height, weight, coordination, and experience.
• Where will it be ridden? Yard, private trails, dunes, or hunting land — terrain affects needed power, clearance, and suspension.
• How much supervision will there be? Younger riders need closer oversight and more restrictive speed control.
• How much maintenance are you willing to do? Gas machines need oil changes, carburetor care, and periodic tune-ups.
• What budget do you have? Include the cost of helmet, protective gear, throttle limiters, and maintenance tools or shop service.

Gas vs Electric: Which Is Better for Kids?

Both types have pros and cons. Here are the main differences to help decide if gas is the right choice.

• Range and refueling - Gas can be refueled in minutes and is better for long rides in remote areas. Electric models need recharging and are limited by battery life.
• Power delivery - Gas engines typically produce more torque useful for hills and trail riding, while electric power is usually smoother and instant.
• Noise and emissions - Gas machines are louder and produce exhaust; consider neighbors and closed environments.
• Maintenance - Gas requires more frequent mechanical maintenance but offers simple field refueling. Electric has fewer moving parts but battery care is essential.
• Weight - Gas ATVs can be heavier, affecting transport and handling for smaller kids.

Sizing: Get Fit Right the First Time

Proper fit is arguably the most important safety factor. A child must be able to control the ATV comfortably. Follow these steps to check fit.

1. Measure inseam and overall height. Seat height should allow the rider to place toes or both feet on the ground when seated for stability.
2. Check reach to handlebar. The rider should grip controls without shoulder or back strain.
3. Test footrests. Feet should rest flat without overreaching the brakes or pegs.
4. Confirm weight capacity. Manufacturers publish limits; exceeding them affects handling, braking, and safety.

Common engine-size recommendations by age and skill:

• 50cc - Best for beginners age 3 to 6 who are learning basics under strict supervision.
• 70-90cc - Typically for kids 6 to 10, offering more capability while still manageable.
• 110-125cc - For experienced riders 9 to 14 who may be ready for steeper terrain and longer rides.

Key ATV Features to Inspect Before Buying

Even within the same engine class, different models vary widely. Focus on these features:

• Thumb throttle vs twist throttle - Thumb throttles can be easier for small hands; twist throttles are common but may be harder to modulate for beginners.
• Automatic CVT vs manual transmission - Automatic transmissions are simpler for new riders; manual or semi-automatic may suit more advanced kids learning shifting skills.
• Electric start vs recoil pull - Electric start is more convenient for kids; but a backup pull start can be helpful in the field.
• Suspension travel and comfort - More travel is better for trails; stubby suspension may be rough and harder for kids to handle.
• Ground clearance - Higher clearance reduces scraping over rocks and roots but increases the seat height which may affect fit.
• Braking system - Disc brakes offer reliable stopping; check for hand controls or foot operated depending on the model.
• Parental controls - Remote kill switches, tether kill cords, or speed limiters give added control for young riders.

Essential Safety Gear in Detail

Proper equipment greatly reduces injury risk. Equip children with certified gear sized correctly.

• Helmet
  • Type - Full-face ATV helmets provide the best protection. Avoid bicycle helmets for ATV use.
  • Certification - Look for DOT, Snell, or ECE ratings depending on your region.
  • Fit - The helmet should sit squarely, with only slight movement when you try to shift it side to side.
• Eye protection - Impact-resistant goggles or helmet face shields protect from dust, bugs, and branches.
• Boots - At least 8-inch, closed-toe, stiff-soled boots that protect the ankle and provide secure foot placement.
• Gloves - Durable gloves with grippy palms improve control and prevent blisters.
• Clothing - Long pants and long sleeves made of abrasion-resistant fabric. Avoid overly loose clothing that could snag.
• Body protection - Knee and elbow pads, chest protector, and a neck brace for aggressive riding or older teens.
• High-visibility gear - Bright colors or a reflective vest increase visibility to others.

Throttle Limiting: Methods, Pros, and Cons

Managing speed is critical for beginners. Throttle limiting can be implemented in several ways. Use conservative limits and test each method in a controlled area.

• Factory or dealer settings - Some models come with an adjustable governor or economy mode. Always check the owner manual first because this is manufacturer-sanctioned and safer.
• Throttle stop screw - An adjustable screw on the throttle linkage that prevents full throttle travel. Pros: simple, inexpensive. Cons: requires careful adjustment and periodic checks.
• Aftermarket throttle limiter kits - Kits designed for your model can give adjustable speed caps. Pros: usually reversible and adjustable. Cons: quality varies; buy reputable brands and follow instructions.
• Throttle cable restrictor - Limits cable pull. Pros: effective for cable-driven throttles. Cons: may change throttle feel and needs professional install for some models.
• Remote kill switches and tether cords - Useful as emergency stops but not a substitute for speed limiting.
• Software-based governors - Less common on basic gas ATVs but available on advanced models; consult dealer for calibration.

Best practice: start with the mildest restriction and increase range slowly as skill improves. Verify top speed using a GPS-based app in a safe area rather than relying on perceived speed.

Pre-Ride Checklist: Step-by-Step

Do these checks before every ride. They take only a few minutes and prevent many problems.

1. Visual inspection for leaks, loose bolts, or damage.
2. Check fuel level, cap tightness, and that fuel is fresh.
3. Check engine oil level and quality.
4. Inspect tires for cuts, punctures, and correct pressure.
5. Test brakes for responsiveness and abnormal noise.
6. Ensure throttle returns to idle smoothly and the kill switch works.
7. Check lights and reflectors if riding near dusk or in wooded terrain.
8. Confirm chain or belt tension and lubrication if applicable.
9. Verify rider is wearing all required safety gear and helmet is fastened.

First Ride Protocol for Beginners

The first few rides should be structured. Follow this progression for confidence and skill building.

1. Introduce controls while the machine is off, explaining throttle, brakes, and stop procedures.
2. Begin in a flat, obstacle-free area, with a low throttle limit set.
3. Practice starting, stopping, and slow-speed turns until the child feels in control.
4. Introduce gentle inclines and varied terrain gradually, watching for fatigue.
5. Teach emergency procedures like how to kill the engine and dismount safely.
6. Limit ride time to avoid fatigue and reduce risk; increase duration slowly as skill grows.

Break-In Period and Why It Matters

New gas engines need a careful break-in to seat rings and bearings properly. Follow the manual, but general advice includes:

• Vary engine speed and load; avoid prolonged full-throttle runs and long idling times during the first hours.
• Change engine oil after the initial break-in interval specified by the manufacturer, usually sooner than routine intervals.
• Re-check fasteners and fluid levels after the first few rides.

Routine Maintenance: What to Do and When

Sticking to a maintenance schedule prolongs life and keeps the ATV safe. Typical tasks and intervals are listed below, but always prioritize the owner manual.

• Before every ride - Check fuel, oil level, tires, brakes, and controls.
• Every 10-20 hours of use - Clean or inspect air filter; check chain tension; lubricate pivot points.
• Every 50 hours or seasonally - Change engine oil and filter; inspect spark plug; check coolant if liquid-cooled; inspect brake system and cables.
• Annually - Full inspection including carburetor cleaning, valve clearance check if applicable, replace spark plug, grease wheel bearings, inspect suspension bushings.

Recommended supplies for basic maintenance:

• Manufacturer-specified engine oil and filter
• High-quality air filter oil or replacement filters
• Spark plug(s) of the correct heat range and gap tool
