The dry weight of the KTM EXC 125 is 110 kg. This weight measurement refers to the weight of the motorcycle without any fluids such as fuel, oil, or coolant. It is important to consider the dry weight when comparing the overall weight of different motorcycles as it provides a baseline measurement. **

The engine of the KTM RC 125 may not start due to a variety of reasons. It could be a problem with the battery, such as a dead battery or loose connections. Another possibility is a fuel delivery issue, such as a clogged fuel filter or a problem with the fuel pump. Additionally, issues with the ignition system, such as a faulty spark plug or ignition coil, could also prevent the engine from starting. It is important to troubleshoot and diagnose the specific issue in order to effectively address the problem and get the engine running again. **

A diesel engine recognizes valves through the use of a camshaft, which is responsible for opening and closing the valves at the correct times. The camshaft is connected to the crankshaft and is synchronized to the engine's rotation, allowing it to control the timing of the valves. As the camshaft rotates, it pushes against the valves, causing them to open and close in coordination with the engine's combustion cycle. This precise timing is crucial for the efficient operation of the diesel engine. **

A moped engine typically does not have valves because it uses a simpler design called a two-stroke engine. In a two-stroke engine, the intake and exhaust processes are controlled by ports in the cylinder wall, eliminating the need for valves. This design allows for a lighter and more compact engine, making it well-suited for the small size and low power requirements of a moped. Additionally, the absence of valves reduces the complexity and cost of the engine, making it more affordable for moped manufacturers and users. **

To overtake the engine of the KTM Duke 125, you can consider upgrading the exhaust system to improve airflow and increase power output. Additionally, you can install a performance air filter to enhance the engine's efficiency. Tuning the fuel injection system and adjusting the ignition timing can also help optimize the engine's performance for better overtaking capabilities. Lastly, regular maintenance and servicing of the engine, such as changing the oil and spark plugs, can ensure it is running at its best. **

The engine of the Yamaha WR 125 is a liquid-cooled, 2-stroke, single-cylinder engine. This type of engine is known for its lightweight design and high power output, making it popular for off-road and motocross applications.

The engine of a Husqvarna WR 125 can last for a long time if properly maintained. With regular maintenance and care, the engine can last for several years and potentially over 10,000 miles. However, the lifespan of the engine can vary depending on factors such as riding conditions, maintenance practices, and the skill of the rider. Regular oil changes, air filter cleaning, and overall mechanical upkeep can help extend the life of the engine. **
