Buyers Guide of Best 4 Stroke Dirt Bike
What is four-cycle engine?
It refers to a type of engine where the combustion takes place is four different cycles. In this type of cycle, the piston should complete four different rotations, mostly preferred to as strokes while turning. In other words, four-cycle engine refers to the movement of the piston along the cylinder in any direction. Besides, strokes come in different varieties — for instance, the exhaust, combustion, intake, and compression.
In intake, also referred to as the suction or induction. In this type of cycle engine, it begins at the top and ends at the bottom. Mostly, the intake valves is located in an open place whilst the piston pulls air into the cylinder and creates a vacuum pressure, which eventually provides a downward motion.
In the exhaust, the piston comes from the bottom to the top while the exhaust pipe is open. Besides, the combustion cycle engine ignites. The cycle engine gives mechanical combustion that facilitates the work. Lastly, the compression one, the stroke engine begins at the bottom and ends at the suction area. The piston power stroke compresses the preparing air mixture. At this stage, the intake and exhaust valves close at this point
2 stroke vs four-stroke what is best?
Well, I can’t easily judge which one is the best. It all depends on your preferences. The difference between the two is how fast combustion occurs in their engines. Well, take a look so as to make the right decision. Both are good, but one tends to outweigh the other.
- 2 Stroke
In 2-cycle engines, the whole process of combustion is just completed by one cycle engine that is the compression stroke. After that, it is then followed by compressing of the fuel. On its return, the outlet lets out a fresh air mixture that goes into the cylinder. On every single revolution, the spark provides fire, and power is gained after every 2 strokes of piston motion. Keep in mind that this stroke ensures that the oil is well pre-mixed.
In this type of engine, the piston ensures that each 2-cycle engine revolution is completed. It features the compression and the exhaust.
On top of that, the return cycle engine follows. Fire is plugged after every movement in each revolution. This ensures that power is produced at every four strokes of the revolution of the piston. They don’t require pre-mixing of the fuel since they feature another compartment to store the oil.
Is a four-cycle engine dirt bike fast?
In most instances, the arguments about which engine is fast are hard to tackle. This depends on what you love and prefer. However, four-cycle engines tend to kick fast as compared to other engines. This is because they pose complex features that enhance their playability. They feature all four types of stroke, compression, exhaust, intake, and compression. Besides, the engine release sparks of fire after every two revolution of the strokes. This typically means that there is more energy delivered, which can be predicted.
Furthermore, these kinds of engines provide a smooth powerband that makes the bike effective to ride. This can be the best dirt bike for mountain trails as it tends to flow easily. The ability to control energy makes the bike fast, and one uses less effort on trials. You can probably have an amazing ride. With the convenience of the great engine size, you can spend less effort on brakes, clutch, and shifting of these four-cycle engine bikes.
However, with additional moving parts, the engines tend to be heavier. This means that they will be a bit expensive as you need to maintain them well. Most riders prefer these types of bikes as they are easy to maneuver with great energy control.
How fast does a four-stroke dirt bike go?
It all depends on the type of four-cycle engines dirt bike you are using. Some bikes with 250 cc can give up to 80km/hr of speed or more depending on the cc of the bike. First, most of the four-stroke bikes are easier to use as they tend to be light due to absence of electric start.
With a light bike that you got much control over, trust me, you can ride at a higher speed. However, with kids and beginners tend to use a low type of speed that is safe for them since they are learning the ways of ridding.
Additionally, the engine has less power but fastens and maintains the power as you ride. This gives you a steady fast speed that you will fall in love with. The good thing about this is that you can rely on the power provided and consistently take breaks whenever you want one.
The speed of the four dirt bikes also varies depending on how well you are gearing the bike, your weight, among other things. This means that everyone can have different speeds while trail riding. Aggressive riders tend to conquer a much higher speed as compared to others.
How Long Can Trail Dirt Bikes Run?
The type of mini bike you want to give your child will determine its operating period. For gasoline-based trail dirt bikes, they’re limited by their fuel tank size. Some bikes will have a 20-minute operational time with a full gas tank.
Take note, the size of the tank can change depending on the brand and model. But in most cases, they have a carrying capacity of 0.2 gallons. In the long run, this type of bike is more ideal since expert riders won’t need to take breaks.
As for electric dirt bikes, they function as long as there’s an electric charge in its battery. It uses a 120V power outlet to charge, and the required amount of time needed to get a full battery varies. The general average is 9-12 hours.
The average operating period for electric bikes is 30-60 minutes. It will depend on whether you’re trail riding at full speed, as well as your weight. But the downside is that you’ll need to finish a full charge cycle before you can use it once more.
Is a four-stroke dirt bike street-legal?
I would say yes. This is because the four-cycle engines dirt bike has a couple of unique features that can be of use when trail riding the bike on the street. First, these types of bikes are not noisy. The calmness of the bike when starting makes it perfect for off-road riding.

How Much Maintenance Does a Dirt Bike Require?
It takes a lot more time and effort to maintain a dirt bike than to take care of a regular bike. After all, you also have a motor to consider. If you’re the parent, you may want to print out or send a file of this section for your off-road riding dirt bike.
Here Are Some Things You Need to do for Your Dirt Bike on a Regular Basis
1. Wash the trail Dirt Bike
You probably should do this after every ride, especially around a muddy track. The key rule is that you take care and wash it gently.
You can get started with some brushes and a bucket of water so you can get rid of the mud sticking to your bike. A pressure washer works too, but then you have to be a bit more careful in aiming it. You’ll want the water to go away from the bike once it washes off the mud. That’s because you don’t want mud and water getting into more sensitive places in the bike.
In fact, even if you use a water bucket you may want to use an airbox cover as a seal for the carburetor.
2. Drying the Bike
The next step to trail dirt bike maintenance is inspection. But you have to do this when the electric dirt bike is absolutely dry. So, after you wash it, you may want to use a leaf blower or a dryer to accelerate the process.
3. Look for Leaks
Now that everything’s dry, you want to check for leaks. Check under the motor, and of course check the ground too. You should also see to it that your brake fluid and coolant fluid aren’t leaking either.
4. Check the Chain
First, you should make sure this is clean. If the drive train is really muddy, you may just want to let it dry while you sleep and then you can take care of it in the morning. By that time, the mud would have dried so you can just use a nylon brush to get rid of it. Then you should a good-quality lubricant for the drive chain. Brands you can trust include Bel-Ray, Maxima, and Klotz.
5. Checking the Chain Tension
There should be some slack to your chain, because this slack compensates for the movement of the suspension. So, it can’t be too taut.
At the same time, it can be too loose too. This is too loose if you can take out the chain from the rear sprocket. You then have to replace it.
A nice compromise here would be to have a half-inch slack for the chain when you have the swingarm parallel to the ground. This should compensate for any suspension movement.
6. Check the Bolts
These bolts could have loosened after going though all that vibration. So, look the hardware over and tighten the bolts as necessary.
7. Look Over the Controls (Including the Cables)
If your clutch and throttle cables are kinked or frayed, then this is time to replace them.
Check the throttle control and that you have just enough free play. You can put the electric dirt bike on a work stand first. Start it up, then let it idle. Now rotate the handlebars as far back as you can in all directions. Did the motor RPM increase? If it did, you need more free play for your throttle cable.
You should also test the responsive action of the throttle control. It has to snap back smartly when you twist it.
8. Cleaning the Air-Filter
The air-filter should be kept clean, so that you maintain your electric dirt bike performance and you avoid any expensive damage to your engine. You can use a premium spray-on air-filter cleaner for this, though you can also use a household cleaner mixed with water. When the filter dries, cover it with a coat of premium air-filter oil.
9. Checking the Tire Pressure
You really should get into the habit of checking the tire pressure before each time you drive your electric dirt bike. That means you need to have a tire pressure gauge. If you’re running on muddy grounds, keep the front tire at 8 psi and the rear at 6 psi. If you’re on dry ground, the front tire should be 14 psi and 12 psi for the rear tire.
10. Check and Change the Oil
Check the manual to see how often you should replace the oil. Some of these manuals will tell you to change the oil after every ride. Don’t complain; your engine lasts longer when you change the oil more frequently.
11. Replace the Brake Fluid
You need to do this every now and then, because brake fluid has this annoying tendency to absorb moisture. That makes the brake fluid less effective. Use DOT-4 alcohol-based brake fluid, as this is recommended for most trail dirt bikes for trail riding.
12. Check the Coolant
Check the coolant level and top off if you need to. Flush the coolant and replace it about once a year.
13. Grease the Necessary Components
Use moly grease, petroleum-based grease, or PTFE-based grease for these areas that need the grease. Apply the grease to the steering head bearings, the rear shock seals and forks, and the wheel bearings and seals. Don’t forget the sealing area of the air-filter, the swingarm, and the hardware.
14. Check the Brake Pads
When there is only 1mm of it left (or if the indicator marks have become invisible), this is time to replace the brake pads.
