Honda CB250F

The Honda CB250F is a series of unfaired motorcycles which were launched in 1996 by the automaker. This is also known as the Honda Hornet 250 and was available only in Japan (Domestic version). But this was made available to the rest of the world as grey imports. Powered by a slightly de-tuned version of the inline 4 cylinder, 4 stroke engine originally found in the Honda CBR250 (Engine code MC14E-XXXX), it produces around 40 PS at 14,000 RPM to its redline of 16,000 RPM. The tuning allows the engine to provide more useful low-end power. The bike features a 6 Speed Transmission and a 16 litre tank. Later models had a dual-tone colored exterior but the dual exhausts found in certain motor cycles are just a modification. This bike is said to emit a peculiar high-pitched whine due to the gear driven camshafts used inside the engine.
