Do you own a 125cc dirt bike for your adventure riding activities? It might bring plenty of excitement while exploring the off-road trails, improving your off-road riding skills, mastering jumps, and feeling the excitement of off-road freedom. Being a responsible 125cc dirt bike owner, you probably want to keep the power and agility of your bike and make it last longer. You not only want it in its top shape but also wish to enjoy the riding thrill that has been going on for years! You need to have regular maintenance of your 125cc dirt bike, which is not only essential to perform better but also ensures safety, longevity, and saves you money in the long run. We at Affordable ATV let you know how to maintain your 125cc dirt bike. We make sure it lasts long and runs like new every time you hit the trail.

Clean The Bike

Dirt bikes run on mud, dust, and rugged terrains. It means all such things, including harsh grime, stay on them. It needs to be cleaned after every ride. So, clean your bike thoroughly after every ride. Use mild soap and water, and make sure to remove the mud and debris from the chain, sprockets, and suspension. Never use high-pressure water on electrical parts and bearings. Dry it properly and lubricate the chain immediately after cleaning. Regular cleaning prevents rust, corrosion, and wear on critical parts.

Keep the Chain Up To Date

Your bike’s chain suffers a huge stress while off-road riding, jumping, and more. A dry or loose chain may not perform better, and it can slip or break during the ride. It is suggested to use a genuine chain lube after 100–150 km ride or after each ride. Read the manufacturer’s manual to adjust the chain tension. Remember that too tight can damage sprockets, too loose can cause derailment. So think wisely before carrying the chain. It will improve the performance and reduce wear.

Take Care Of the Engine Oil

Engine oil is the life force of a 125cc dirt bike engine. Check the user manual and change the oil or change it after every 10–15 hours of riding! It is suggested to use premium-quality engine oil to ensure smooth engine performance. It will keep the engine cool. Never forget to change the oil filter from time to time. Fresh engine oil protects the 125cc dirt bike engine from premature wear.

Clean or Replace the Air Filter

An air filter traps dust and dirt while riding the dirt bike. It protects dust and dirt before they enter the engine. But it may get clogged over time. It will affect the performance and fuel efficiency. So, it is wise to clean your air filter regularly because you ride in dusty and damp areas. You can even replace it if you find there is a sign of wear or a tear. A clean air filter ensures proper airflow. It will keep your engine healthy.

Inspect the Tires and Pressure

Premium-grade tires in a 125cc dirt bike are crucial for grip, stability, and handling. It is necessary, especially on uneven terrains. Check the tire pressure before each ride and adjust it based on the type of terrain. Inspect the tire to check for cracks, cuts, or worn-out treads. Replace tires when the rubber bits or grips become too thin. It is not perfect for off-road traction. Remember that properly pressured and well-maintained tires offer better performance, safety, and smoother rides.

Check the Brake & its Performance

Brakes are your lifeline while riding the 125cc dirt bike on trails. So make sure to check the brake pads frequently and replace them if they’re thin or glazed. Inspect brake fluid levels and top up if needed. Test the brakes before every ride to ensure immediate response. Strong brakes keep the riders safe during sudden stops or downhill descents.

Check the Bolts, Suspension, and inspect the lights.

Dirt bike rides cause vibrations that can loosen nuts and bolts. A loose bolt can compromise handling or safety, so tightening them should be a routine part of your inspection! Inspect lights, ignition switches, and wiring for damage, especially after muddy rides.

Store Properly

When not riding for extended periods:

Keep your dirt bike in a dry, covered place. Start the bike to keep fluids circulating and parts lubricated. Proper storage prevents rust and mechanical degradation.

Maintaining your 125cc dirt bike doesn’t require expert mechanics. Your constant care and attention ensure better performance while extending your bike’s lifespan significantly.
