The rebuild cost of a two-stroke dirt bike can vary significantly depending on the bike's make, model, and extent of the repairs needed. On average, a top-end rebuild, which includes replacing the piston, rings, and gaskets, can range from $300 to $800. A complete bottom-end rebuild may cost between $800 and $1,500 or more, depending on the parts and labor involved. Additional costs for performance upgrades or aftermarket parts can further increase the total expense.
A 125cc four-stroke dirt bike typically reaches speeds of around 50 to 60 mph (80 to 97 km/h), depending on factors such as the rider's weight, terrain, and bike modifications. Four-stroke engines tend to provide more torque and smoother power delivery compared to two-stroke engines, which can affect acceleration and overall performance. However, the actual top speed can vary by model and manufacturer.
Any bike can be used to race. The XR80R is a 4-stroke engine so even though it is an 80R, it is not traditionally considered a race bike. The Honda CR series are considered race bikes. They are 2-stroke engines.
No, you should not put 2-stroke oil in a 4-stroke dirt bike. 2-stroke oil is designed for engines that mix oil with fuel for lubrication, while 4-stroke engines have a separate lubrication system that uses engine oil. Using 2-stroke oil in a 4-stroke engine can lead to improper lubrication, increased smoke, and potential engine damage. Always use the recommended oil type specified by the manufacturer for optimal performance and longevity.
A 4-stroke bike typically runs on gasoline, which is a common fuel for internal combustion engines. If it has no 4-stroke engine components, it might be powered by an alternative engine type, such as a 2-stroke engine or an electric motor. In the case of a 2-stroke engine, the fuel is usually a mixture of gasoline and oil. An electric bike would rely on batteries for power instead of any fuel.
2 stroke engines are not widely used on street bikes because of the vibration, It makes for a shaky bike and the sudden spurts of power are somewhat undesireable. Since the majority of 2 stroke engines are meant for off road use it is a matter of necessity to have a kick start. If you are out riding in the woods or desert which is where the bike is meant to be a dead battery or faulty starter would mean hours of pushing to get to a road, the kick start eliminates that huge hassle.
An enduro bike is specialised for nature of the sport, with the deep suspension of a motocross bike combined with the features required to make it legal for the public road portions of the course. Engines are generally single-cylinder two stroke between 125 and 300cc. or four stroke between 250 and 650cc. It really is a mix of a road bike and a dirt bike. it has the knobby tires and suspension of a dirt bike, but the characteristics of a road bike too.
It's how the engines work. for the same amount of power, a 2-stroke will be lighter, smaller and rev higher. It'll also use more fuel and pollute more. A 4-stroke will run cleaner and more efficiently. It'll make more torque but won't rev as high.
A 125cc dirt bike typically runs on regular unleaded gasoline with an octane rating of 87 or higher. Some models may require a mix of gasoline and two-stroke oil if they have a two-stroke engine, while four-stroke engines use straight gasoline. Always refer to the owner's manual for specific fuel requirements for your bike.
It's a dirt bike that uses a 2-stroke engine.

There are electric bikes(which usually legally are considered bicycles) and there are bikes with combustion engines.(which usually are seen as either scooters/mopeds or motorcycles by the law.) For the combustion engines you can have either 2-stroke engines(which usually are fairly small) or 4-stroke engines. You can have one cylinder, or several. Then there are a few custom builds with turbine engines and the occasional drag/showbike with jet, or rocket engines. Most bikes run on gasoline, but there are Diesel bikes too.
