Motorcycle Engines and Parts for Hyosung GT250R
Korean motorcycle manufacturer Hyosung Motors & Machinery, now operating as KR Motors, introduced the Hyosung GT250R in 2005 as a 250 cc class sport bike. Also known as the Hyosung Comet or Hyosung Blade in some markets, the GT250R has an air/oil-cooled V-twin engine with four valves per cylinder and a double overhead cam, with later models replacing the carburetor with fuel injection. Here, you will find Hyosung GT250R engines and other parts and accessories to keep your Hyosung operating safely and smoothly.
What is the difference between DOHC and SOHC?Compared to single overhead cam, double overhead cam has two camshafts. In SOHC, intake and exhaust valves are operated by the same cam. In DOHC, one cam operates the intake and the other cam operates the exhaust. With DOHC, more cams means more valving can be directly actuated by the cams, increasing air intake and exhaust flow. Your Hyosung GT250R uses DOHC.
What is the value of an oil cooler?An oil cooler keeps the oil in your Hyosung bike from breaking down due to high temperature by circulating the oil through a radiator cooled by flowing air. An oil cooler also contributes to cooling the engine, which may reduce pinging noise. Both high oil and high motor heat are problems that can become serious and potentially damaging to your vehicle during long distance riding in hot weather. Installing or replacing an oil cooler on a Hyosung is usually considered a minor mechanical effort. However, as always when purchasing parts, make sure to check the fitment applicability for the model and year of your Hyosung GT250R parts. Also ensure that a kit includes all the Hyosung compatible parts you need to complete installation.
What is the difference between a camshaft and a crankshaft?A camshaft and a crankshaft serve two entirely different purposes in your GT250R motorcycle. The camshaft controls the opening and closing of the cylinder air intake and exhaust. The camshaft ensures the pistons can fire properly and the engine is able to function. The crankshaft is driven by the motion of the pistons and converts their power into rotational torque, which is conveyed by the chain drive to the rear wheel of your GT250R motorcycle. Without the crankshaft, the motor could run, but it would not be able to turn the wheels regardless of clutch position.
What are the brakes like on the Hyosung GT250R?Your Hyosung GT250R has a 300mm front disc brake setup with twin-piston calipers, and also a 250mm rear disc brake.
What kind of suspension does the Hyosung have??The bike comes with 51mm USD Forks front suspension and mono shock, preload adjustable rear suspension.
