Since its launch in April 1986, the CBR250FOUR was popular for its sporty equipment and driving taste, such as the precision engine that drives the camshaft with gears which is the only one in the 250cc class, and the lightweight and highly rigid aluminum frame. Following that, a type of "Honda CBR250R 1987" with enhanced equipment and improved output characteristics released on March 20th 1987.

Old but Gold, 1987 Honda CBR250R Features

This 1987 Honda CBR250R has a sportier design, such as a new full-covered fairing with an accessory case with excellent aerodynamic characteristics and a front-rear separation type seat.

In addition to the conventional aluminum frame, lightweight and highly rigid aluminum rear forks are used for the rear wheels, and duralumin pedals are used around the steps. Furthermore, the rear wheel brakes have been changed to disc type, and the equipment has been further enhanced, such as triple (three) disc brakes with two front wheels and one rear wheel.

The engine is a water-cooled, 4-cycle, DOHC, 4-cylinder engine that drives the camshaft with gears. In addition to increasing the bore diameter of the carburetor and increasing the capacity of the exhaust pipe (made of stainless steel), the diameter of the intake and exhaust valves has been increased. The intake and exhaust efficiency is improved by making the shaft thinner (4.0 mm → 3.5 mm).

In addition, the red zone entrance of the engine speed has been improved from the conventional 17,000 rpm to 18,000 rpm by pursuing thorough weight reduction of reciprocating motion system parts such as reduction of the inertial weight of the valve train, piston pin, and crank system. I'm letting you. These make it suitable for agile and responsive sports driving in a wider rev range from low rev range to high rev range. Also, the standard cash price is kept to 10,000 yen higher than the conventional type.
