1986 Honda CBR250FOUR MC14 Review
This newly designed engine realizes more accurate valve operation and reduction of frictional resistance at high rpm by driving the camshaft with gears. In addition, we thoroughly pursued weight reduction of reciprocating motion parts, such as by adopting a chrome molybdenum carburized connecting rod. In addition, a design that makes the intake path from the new 4-unit carburetor to the combustion chamber almost straight and the adoption of a large-diameter valve realizes high intake and exhaust efficiency. As a result, the engine is agile and responsive in any rev range, from low rev range to high rev range, and is suitable for sports driving.
The CBR 250 FOUR motorcycle’s body adopts an aluminum twin tube diamond type frame that adopts a lightweight and highly rigid “eye-shaped” cross-sectional structure by Honda’s original manufacturing technology. In addition, the undercarriage includes cast aluminum wheels with newly designed “S-shaped” cross-section spokes that combine the light weight and high rigidity developed for motorcycles for competition, and newly designed flat tires (front wheels 80%, rear wheels). 70%) is adopted. In addition, a light super sports bike with excellent road followability by adopting an extra-thick rear wheel swing arm (prolink type suspension) and de-carvone type rear cushion that match the characteristics of the reinforced frame and flat tires. It has become.
The design of Honda CBR250 FOUR adopts a large front fender born from thoroughly pursuing aerodynamic characteristics to reduce rider fatigue, a half fairing (windshield) integrated with headlights, a rear cowl, etc. .. Together with the new tank shape, these create a strong and beautiful form that makes you feel like a new generation super sports bike.
