The 4-stroke engine road racer, RC211V, has been developed with concept as “Launching of Honda’s own advanced technology in pursuit of speed and functionality”. Employing a light and compact 4-stroke V-type 5-cylinder engine for the first time in the world, it was aimed to realize linear torque characteristics, easy operational traction characteristics, high controllable handling by mass concentration and better turning ability than 2-stroke road racers. A semi dry sump crankcase utilizing the transmission room for oil tank, and pressure controllable fuel injection system were adopted to achieve the performance target of engine. In addition, the specified minimized weight, 145 kg, for 5-cylinder engine motorcycles was satisfied by employing of a new type of aluminum twin spar frame, a low gravity fuel tank and a Unit Pro-link suspension on the frame body and the suspension, as well as by weight reduction of each part.
