Most of the time, replacing parts of the Cross 2-stroke 125cc bike can be a DIY project. To cross 2 stroke 125cc dirt bike fans, here's a simple guide on how to replace some common bike parts.
Replacing the air filter:
Get a new air filter that suits the dirt bike. Open the air box by loosening the screws. Take out the old air filter and put in the new one. Ensure it fits well and close the air box.
Changing the spark plug:
Find the spark plug under the bike's seat or near the engine. Use a wrench to loosen and take out the old spark plug. Put the new spark plug into the hole and tighten it carefully. It's important not to tighten it too much.
Replacing brake pads:
Take off the wheel where the brakes need changing. Take out the old brake pads from the brake caliper. Put in the new brake pads and bolt up the brake caliper. Then, put the wheel back on.
Oil change:
Take out the old oil by draining it into a container. Then, pour in the new oil until it reaches the right level. Remember always to check the oil level using the dipstick.
Tire replacement:
Use tire levers to take the old tire off the wheel rim. Put the new tire onto the rim and ensure it sits properly. Inflate the tire with a pump until it feels firm.
Fueling up:
Fill the tank with petrol or gas. Always mix in the right amount of 2-stroke oil. This keeps the engine running smoothly and prevents damage.
Setting up the suspension:
Look for the adjusters on the forks and rear shock. Use a spanner to make the suspension harder or softer, depending on how it feels when riding. Adjust the height of the seat if needed to suit the rider's preference.
Reassembling:
After any repairs or maintenance, ensure all screws, bolts, and parts are tightened and in place. Double-check everything before riding the bike again.
Remember to follow the instructions carefully and ask an adult for help if needed. Taking care of the dirt bike will make it last longer and perform better. Enjoy the ride!
Q1: Are 125cc 2-stroke bikes good for beginners?
A1: 125cc 2-stroke bikes can be appropriate for beginners with some experience or training, like riding dirt bikes. They have a peppy and responsive engine that requires smooth handling of the throttle and brakes. New riders need to be trained properly before attempting to ride a 125cc 2-stroke bike safely and effectively.
Q2: How fast can a 125cc 2-stroke bike go?
A2: Most 125cc 2-stroke bikes can reach top speeds between 55-70 mph (90-112 kph) on flat roads under ideal conditions. The exact speed depends on the bike's make, model, and other factors like rider weight and wind resistance. Some performance-oriented 2-stroke models may achieve slightly higher speeds.
Q3: How does maintenance compare between 4-stroke and 2-stroke engines?
A3: Generally, 125cc 4-stroke engines require more routine maintenance than 2-stroke engines due to their additional moving parts. 4-stroke engines need regular oil changes, while 2-stroke engines use oil mixed with fuel, requiring less frequent oil system maintenance. 4-stroke engines tend to be cleaner running, meeting more emission standards than most 2-stroke engines by design.
Q4: Can 125cc 2-stroke bikes be used for long-distance touring?
A4: With proper planning and some considerations, 125cc 2-stroke bikes can be used for long-distance touring. However, their fuel tanks require more frequent refueling stops compared to bikes with larger fuel tanks. 2-stroke engines also use more fuel than 4-stroke engines. Their engine vibrations and seating ergonomics may not be as comfortable for long rides.
Q5: Is a motorcycle license required to ride a 125cc 2-stroke bike?
A5: In most places, a motorcycle license is required to legally ride a 125cc 2-stroke bike on public roads. There are specific licensing requirements for different countries and states, such as completing a rider training course and passing written and practical exams. Some jurisdictions have cc (cubic centimeter) restrictions for licensure, allowing only smaller engine displacements.
