Honda Nighthawk 250
The Honda Nighthawk 250 is a Honda standard motorcycle. It has a 234 cc (14.3 cu in) air-cooled parallel-twin engine. While the first Nighthawk (CB650) was manufactured in 1982, the first 250 Nighthawk was manufactured in 1991. It utilized the 1985–87 CMX250 Rebel engine with all new wiring and components and reshaped the Rebel cylinder head slightly as well as incorporating a larger carburetor and new valve cover. The motorcycle changed little over the years except for color. The Nighthawk 250 is essentially a light, maneuverable, inexpensive, economical, and easy to maintain bike. It is often used in Motorcycle Safety Foundation (MSF) motorcycle training. Its small size and low seat make it a popular model for riders of smaller stature. It has drum brakes and spoked wheels at front and rear, though later models in the Australian, U.K. and Japanese markets upgraded to front disc brakes and alloy wheels.
